Macsales: ? Happiness Is A Faster Macssds Built For Mac

Tuesday, December 10th, 2013 Author: If you’ve researched using an SSD before, you may have heard how they can slow down over time. Most manufacturers go out of their way to avoid this by suggesting users run TRIM, a command for cleaning up “garbage” files. But what if you had an SSD so advanced, with a perfect combination of technologies designed to stay at peak performance and speed throughout its life that you had? Well, you’d have an, of course! First, we should note that support for TRIM is based on the operating system and the SSD manufacturer. Microsoft Windows began to natively support the TRIM command for SSDs in Windows 7. Apple added TRIM support in 10.6.8, however Apple does not natively support TRIM on non-Apple SSDs.

Build-a-Lot: The Elizabethan Era is rated 4.5 out of 5 by 11. Rated 5 out of 5 by normaster1 from timed building game It starts out easy and gets harder as it goes from town to town.

There is a way to hack the Mac OS to support TRIM on non-Apple SSDs, and we will get into that later on. But before we go further into what TRIM is and why you do not need to be concerned about enabling it on your OWC SSD, let’s take a closer look at some SSD basics. When data is written to a new SSD, that data is stored in small pieces called “pages”. These pages make up blocks, which make up the SSD.

Let’s think of pages as a house, a block as a city block, and the SSD as the city. SSDs keep track of which pages have information saved on them, and this is called the Logical Block Address (LBA). Think of the LBA as a city registry that knows where everyone lives. Related: When data is written to the SSD, it is first written to the empty pages. In our analogy, a family would move into an empty house within the city block first.

When data is deleted from an SSD, the information is not actually deleted. The reference of the data is removed from the LBA, but the data is not actually erased. This lingering unused data is called invalid data. It is like a family moving out of the house and having their name removed from the city registry, but leaving all of their belongings behind. Having this leftover information means no further information can be written to the block before it is completely erased.

Once the SSD starts running out of empty pages, it will begin looking for invalid pages that can be erased, but SSDs cannot erase just an individual page. It must erase the entire block so the task of relocating the valid pages of data is created.

This movement of valid data to different blocks on the SSD is called write amplification. Moving valid data to another block and then erasing the invalid data is a lot of work compared to normal write operations. In our city analogy, to allow a few once-occupied houses within a city block to be moved into, we must first move all of the tenants of the other houses on the city block to a completely different city block.

Workers then have to go back to all of the houses on the city block and clear out of all the belongings before new tenants can move in. This extra work is what causes SSD performance to dramatically slow down over its lifetime, and it occurs when the drive is in use, further slowing performance.

So what have manufacturers done to avoid this slow-down? A technology called garbage collection was built into SSD controllers to help automatically reset the data blocks back to free space. Garbage collection will take the data pages from their current block and move them to a new block. This will then allow the old block to be erased and reset back to empty space.

This process will ensure that there is free space readily available for new data to be written to quickly, without any extra erasing and moving steps. Garbage collection will move both valid data and invalid data (deleted files) from the old block to the new block. Garbage collection is a lot like having a moving company that moves all the furniture and people from their existing city block to a new city block.

This process moves both the valid tenants (valid data) and the vacant house belongings (deleted data). The moving company then goes back to the old block and gets the houses ready for new tenants to move into.

The garbage collection occurs when the drive is idle, so performance is not affected. So where does TRIM fit in? TRIM is an operating system-based command for SSDs that is activated when you delete a file on the SSD.

When you delete a file from your computer, TRIM notifies the SSD that the location of the deleted file no longer contains valid data. TRIM then works in conjunction with the SSD’s garbage collection process to move both valid and invalid data from the old block to the new block. Having TRIM enabled prevents the invalid data being moved. This in turn frees up space on the SSD and reduces write amplification. Now the “moving company” only needs to focus on moving the current tenants and ignore the vacant homes. Apple added TRIM support in 10.6.8, but only for the SSDs they build into Macs.

There are utilities and command line prompts available that hack the operating system to allow TRIM on other drives. While this can be beneficial for the majority of non-Apple SSDs that rely on TRIM to maintain their speed, performance, and reliability, it is important to remember that a hack in this context is the alteration of software that the original programmer did not intend to be possible. There is a risk of negatively impacting your computer and or data by enabling the hack, it can also be nullified through a future software update released by Apple. By enabling the hack, you are taking a gamble with your computer’s functionality and your data. This is another reason OWC does not recommend enabling TRIM on your Mac. Now that we have an understanding of SSD basics, let’s take a look at what makes OWC Mercury SSD lineup stand out against the rest. All OWC Mercury SSDs.

have a SandForce Processor installed. SandForce processors improve an SSD’s performance and reliability. A key feature of SandForce processors is the DuraWrite technology. DuraWrite is a technology that helps reduce write amplification.

As discussed earlier, write amplification is the act of data on the SSD being moved from block to block. Write amplification is expressed as multiples, based on how many times the data has been rewritten since it was passed to the SSD. This equation is calculated by taking the total amount of data written, then dividing it by the actual size of file. For example, a 2.0MB file is written to the SSD. Through garbage collection, it had parts of the file rewritten around the SSD totaling 5.0MB of data moved. The write amplification would be expressed as 2.5x.

DuraWrite helps reduce write amplification by compressing files that are written to the SSD. This compression can lead to write amplification that is less than 1x.

Using the previous example, a 2.0Mb file that is written to an OWC Mercury SSD can potentially only take up 0.5Mb of space on the SSD. The write amplification would then be 0.25x. Compressing files means less data is written to the SSD which increases performance, reduces wear on the drive, and makes garbage collection more efficient. This is just part of what keeps an OWC Mercury SSD as blazing fast at the end of its life as it was its first day.

We have even seen our drives Another feature of our SSDs is over-provisioning. Over-provisioning is reserving a portion of the drive’s total capacity for performance and maintenance tasks, and it’s the reason our SSDs come in non-standard capacities like 240GB instead of 256GB. The majority of OWC Mercury SSD have 7% over provisioned space. This additional free space available means that the SSD always has room to adequately perform garbage collection and won’t slow down even at its max capacity.

A 240GB Mercury Electra 6G with only OS and QuickBench installed. Through the DuraWrite technology, over-provisioning, and the garbage collection in the SandForce processer of our OWC Mercury SSDs, the need for TRIM is negated. If the firmware on your OWC Mercury SSD is up to date you can enable TRIM, but we’ve found no benefit in doing so since everything you need for top performance is built right in. Right from the start, the speed of your OWC SSD is stunning. It truly makes an existing Mac feel like it’s brand new again. And rest assured, you will enjoy that same speed for the life of that Mac and even beyond!.UPDATE: Since this article was published, OWC has also released that use an equally impressive Silicon Motion controller. Hello OWC, I have a question concerning to garbage collection.

You said it not only moves out valid data, but invalid(deleted) data in the block. But is moving invalid one necessary? Since if controller moves both to a new empty block, the invalid data is still at the new block, which is helpless to produce new empty pages in terms of whole ssd(only leaving uncleaned room). Accordingly, ssd would filled up sooner or later.

Is this is true, how could manufacturer solve it problem without using TRIM? Hi I’m running OS X El Capitan on my MacBook Pro 13″ early 2011 machine. Since Apple has now officially allowed 3rd party SSDs to use the TRIM support in OS X (starting from 10.10.4) through their “trim force” UNIX tool, is it advisable plus safe to use it against your OWC Mercury line of SSDs. I know that your article said otherwise. But that was before Apple had an official TRIM support.

Or does this news not affect your SSDs at all and you still stand by the notion that your Mercury drives are in need of TRIM support? In that case, does enabling TRIM affect your SSDs in a negative way? I have a question about securely erasing a SSD (any SSD actually). Is it true that it’s not possible to securely erase a SSD like a traditional HD? I have been reading on the internet and haven’t found any software that will securely erase a SSD. Could I simply fill the SSD with “junk data” that will overwrite any data that is already on the SSD? I have several terabytes of video data the I could copy to the SSD to “replace” the data to put data on the SSD that I’m not worried about being retrieved.

What do you think? It is true that traditional data wiping procedures do not work on SSDs. On a HDD you would “zero the drive” which means you write a bunch of 0s on the drive platter which would overwrite all the old data. SSDs handle data management in a very different manner than HDDs. As the article above mentions data is constantly getting shuffled around SSD to help maintain the performance and ensure wear leveling on the flash modules. There is no recommended method for securely erasing a SSD.

Old deleted files will be eventually securely erased through the normal use of the drive. This is very interesting reading. I installed a new OWC SSD Mercury drive into my macbook pro a few months back. Everything was working fine.

Great performance and I never activated TRIM. This afternoon I found my mac will no longer boot.

I’m stuck at the “gray screen.” I cannot boot into Recovery mode, Safe mode, or boot off an external drive. I CAN get to Single User mode and fsck reports no problems.

I also was able to do a fresh install of Yosemite by putting my mac in target mode and using another machine. Reset the NVRAM.

Still no dice. Stuck at the gray screen.:( Any suggestions? Try booting with the verbose mode enabled, so you can see what’s going on behind the gray screen. Sometimes what you’ll see here is the last thing that worked ok, not what’s failing, but it’s worth a shot. If you enable this mode permanently, and watch it every time the computer starts up, then you may be able to figure out a problem that occurs later (yea, I know it’s a bit late for this one, heh). This is done by running the Terminal emulator (in your Utilities folder) and then entering this on the command line: sudo nvram boot-args=”-v” Then enter your admin password when prompted.

I think this can be done when running in the single use mode, but I have never tried it from there. The is a great drive, however it utilizes a not a Sandforce controller. Over Provisioning can be done to any SSD simply by adding a free spaced partition to the drive. Over Provisioning certainly helps SSDs maintain their performance in conjunction with their Processor’s built in garbage collection, however it is only one piece of the puzzle to help ward off a SSD’s slow down over time. Having a processor with really aggressive garbage collection and other technologies (like Sandforce’s Durawrite) all come together to help SSDs maintain their performance. Hi, Few week ago my new OWC 240GB Mercury Electra 6G SSD arrived and just today I’ve got a time to install it in iMac 21.5” (Late 2009) with Data Doubler (optival bay) Earlier I downloaded OS X Yosemite from App Store and made bootable USB.

Double click DL100_1411a.dmg to start up Driver Loader. Download the Driver Loader DL100_1411a.dmg. Sony dsc w170 driver for mac. DetailsIf you are running on Mac OS X version 10.10, running DriverLoader, a preparatory application, is necessary before software updates.

On the restart I booted from USB and started install proces on the new SSD, but the proces stoped, just before the installation proces restarts and writes some error I tried it few times but always stuckes at the same time. Can anybody help me please. Now I tried to make fresh install to original HDD (500GB disk) it works just fine. But thats not the point of SSD inside my iMac. Once more plaese if someone knows what’s wrong or I done something wrong???

I just installed a OWC Mercury Electra 3G SSD into my Macbook Pro Mid 2010 build. I had already been running OS X Yosemite. Unfortunately Yosemite was installed with FileVault.

I decided I was going to erase the SSD and reinstall Yosemite at the Apple store as I was advised that system files can become corrupt over time. The Genius Bar tech initiated the turn-off file vault which has just completed however now when I go to Disk Utility to erase the OWC SSD all the options are greyed out. Can you suggest what can be done to safely perform this intent without damaging the OWC SSD? I want to use an SSD in an external configuration in a portable enclosure using USB3.0 to capitalize on the speed of the SSD. I’ll be using with my iMac and MBPRo. I just talked with a Samsung tech support guy who warned against using any of their SSD drives in that way since they require using TRIM and TRIM doesn’t work by using the USB3.0.

He said I’d have to use it in a SATA configuration internally. It sounds like OWC is saying that by using over provisioning and Garbage Collector that going external is perfectly fine to do. Is that the right conclusion to take away from this TRIM vs. Non-TRIM discussion with OWC SSD’s? Thanks, Gary. If garbage collection copies the entire page, blocks containing erased files and all, then won’t those blocks still require clearing the next time the drive tries to write to them?

Assume I have 2 pages: one empty (A), the other with a mix of data and erased data (B); if B gets moved to A, and B is then cleared so it can be overwritten. Doesn’t that leave me with 1 page ready for writing and 1 page with blocks that will require clearing before writing? I don’t understand how garbage collection is prepping blocks containing erased data for writing, since it can’t distinguish between valid & erased blocks. But the OS won’t tell the drive to write to a previously used address until all of the free space is used up. From then on we have a full SSD that will never have much in the way of free space on it.

Is there a way to force it to reclaim the space used by invalid data? The reason I ask is that I recently installed a 120GB OWC drive. Beforehand I went through the old drive and deleted anything I didn’t need. However, a couple of days after I copied everything (about 65GB) to the SSD I discovered a folder with 25GB of music and stuff that had been stored in the the documents folder of the root directory?!? It hadn’t even occurred to me to look there when I was doing the previous culling. So, I’m rather annoyed that I have used up almost a third of the space I would have had if I’d noticed this folder 4 days earlier.

“But the OS won’t tell the drive to write to a previously used address until all of the free space is used up.” We users don’t have any direct way to know what the OS is doing. As far as I know, the source code for the disk driver has not been made public.

Faster

I suspect storage blocks are reused before the disk has been written all the way to its end. If you wanted to discover what actually happens, you could run the Corilois defragger demo, take a look at your disk, delete the 25GB music folder, then create or copy some new stuff (large files will be easier to see) on to the disk, and look at where that went. I’d appreciate knowing the results of this, heh iDefrag will display individual files IF they are fragmented (click on the Files tab, then double click a file from the list this displays), but not folders. You may be able to get an idea of where the unwanted music folder and files are, if any of them became fragmented, although that’s not likely as they were just copied over to the new disk, and should have all wound up in one group of contiguous blocks. “Having TRIM enabled prevents the invalid data being moved.” This would seem to be a big advantage. Since OWC uses LSI Sandforce controllers and LSI extolls the virtues of TRIM.

( see LSI website the “learn” tab – download the ‘performance” white paper titled “SSD Over-Provisioning And Its Benefits” then see page 7 quote: “Using TRIM with DuraWrite technology, or similar combinations of complementary technologies, can yield even more impressive results.”) I can understand the liability issues if OWC recommends enabling TRIM through a minor hack ( and it is minor ) but technically TRIM is superior ( as the Sandforce controller manufacturer extols in the paper noted above ). Good morning, if not the thread, or I should direct this query to another site. I have installed a SSD OWC Mercury Extreme Pro 3G in a MBpro 15 “Intel Core 2 Duo, OS X Mavericks. During the test conducted in W/R do not get speeds above 70/130 MBs. I’ve made an installation of clean OS X, and has not changed the speed of the SSD, I do not have TRIM enabled.

I do not know if the problem is solvable, since the test indicate that the speed of this SSD is about 200 MBs W / R. If are so friendly I can help, I would be very grateful. There’s not quite enough information here to give a definitive answer, but I suspect it is a combination of two things.

First, it depends on which 15-inch MacBook Pro Core 2 Duo machine you’re running. Machines prior to the Late 2008 models have a SATA Revision 1.0 drive bus which means a maximum theoretical throughput of 150MB/s in which case the read speed is definitely up to par in that machine. Second, it really depends on the benchmarking suite you’re using and whether the suite itself uses compressible or incompressible data for the results. I suspect again that you’re using the free BlackMagic benchmarking suite (which always seems to rank at the top when searching the Mac App Store for benchmarking).

BlackMagic uses incompressible data in its testing. On a SandForce-based drive, this would report lower speeds, since the Durawrite technology used in the Sandforce controller compresses data in part to achieve its speed. The BlackMagic test is good for a worst case scenario of write speeds. We’ve found that the QuickBench Speed Tools benchmark (which uses compressible data in its testing) shows more accurate speeds for the average user. BlackMagic does performance testing to help determine suitability/capability for various video-related functions.

Raw video capture deals with compressible data whereas conversion and editing of already compressed video file types is dealing with incompressible data. If the purpose of your benchmarking is for the optimization of a video production workstation, then BlackMagic would be the test to use – for most other purposes it isn’t going to give real-world results. Based on your description: TRIM improves on Garbage Collection in that the Operating System tells the Garbage Collector which pages are invalid (have deleted data). Therefore the Garbage Collector only has to move the valid pages to the new block before erasing the old block. Without TRIM, the Garbage Collector moves both the invalid pages and the valid pages to the new block before erasing the old block – doing much more work in the process.

TRIM thus makes Garbage Collection more efficient and faster. TRIM isn’t really necessary on any SSD that has Garbage Collection in that Garbage Collection will happen anyway. TRIM just makes Garbage Collection faster since it moves less data to new blocks. And Garbage Collection happens when the drive is idle so that it doesn’t slow writes down. The only time Garbage Collection bogs down is when the SSD is too full.

Then Garbage Collection cannot occur efficiently and the drive slows down. OWC SSDs prevent the SSD from bogging down when it gets full by: 1.

Compressing Data before it is written – thus reducing the number of SSD writes, and preventing the SSD from getting full. Always keeping extra free blocks to use for Garbage Collection (overprovisioning) to make sure the drive never gets too full. Thus, OWC SSDs reserve 32 GB (7%) out of a 512 GB SSD for Garbage Collection only, leaving 480 GB of free space. This prevents the SSD from getting too full that Garbage Collection cannot be done efficiently. This keeps OWC SSDs running at peak speed and minimizes writes to lengthen their longevity.

Since OWC SSDs can keep their peak speed even without TRIM, they don’t need TRIM. —– IMPORTANT POINTS: 1. Since TRIM simply speeds up Garbage Collection by avoiding writes of invalid data, having TRIM ON should not be expected to harm OWC SSDs – since it also speeds OWC SSD Garbage Collection by preventing it from doing extra work – even if it doesn’t improve on OWC SSD speed. Thus, when running a system with mixed OWC SSDs and other manufacturer SSDs, based on this information, it is best to simply keep TRIM ON since it helps the SSDs which don’t have OWCs data compression and overprovisioning capabilities more efficiently do Garbage Collection. Since Garbage Collection bogs down when the SSD is too full, it is best to NEVER fill a non-OWC SSD to its capacity if it does not have overprovisioning. Just like hard drives, SSDs without overprovisioning bog down if too full.

Mac OS X – in particular – does a lot of writes to the hard drive or SSD. In the past, the rule of thumb is to keep at least 20% of the hard drive space free to keep the OS functioning without bogging down. This advise may also be true for SSDs which don’t have OWC’ SSD’s special features. More entropy in data (the less they can be further compressed) means less benefit from the DuraWrite architecture.

Go here – and scroll down to the “Impact of Data Entropy” section. Encryption has (or, should have, heh) high entropy. More detailed info from Intel is here – Data Compression in the Intel® Solid-State Drive 520 Series So. My advice would be to always leave some free space on the drive. OWC provides 7% on their end-user models, and 28% on their enterprise devices.

This is called static over-provisioning. The free space left unused by the user is called dynamic (because it varies depending on usage) over-provisioning. Quoting one of the LSI articles I will cite below – “When less data is stored by the user, the amount of dynamic OP increases, further improving performance and endurance.” The question is, how much free space is enough? I don’t know, but I’d guess if the drive is being hit heavily with writes of high entropy data then 28%-7%=21% would not hurt. As for TRIM, it’s a SATA-only command.

It’s not available via Firewire, USB, or Light Peak/Thunderbolt, and while I haven’t yet looked at PCI, probably not there, either. So, since people will want to use SSDs on these buses, the SSDs will need to function reasonably well without the benefit of TRIM commands. The patch to enable TRIM for non-Apple drives is pretty simple, the string “APPLE SSD” in the driver is replaced with nulls, allowing anything and everything on the SATA bus to be sent TRIM commands. There was one person selling a TRIM enabling tool that replaced the entire driver with one from an earlier release of OS X. That’s not only just plain crazy, but the problems this created also led to a lot of unnecessary fear of doing it, at all. That said, patching a driver is not something inexperienced or non-techicnal users should be doing, and there is always the chance that an operating system update will overwrite your patch when a new version of the driver is installed.

Worse, Apple could change the driver, and the patch that used to work could result in an unbootable system. Here are a couple of articles about TRIM. They’re quite well written, and I think they’ll not only be easy to follow for just about everyone, but go a long way towards removing a lot of the confusion about the value of TRIM –. Recent Posts.

I have a new, late 2011 MacBook Pro, and I was wondering about certain upgrades.namely, RAM and graphics. To start off, here are the specs: 2.5 GHz Quad-core Intel Core i7 4 GB 1333MHz DDR3 SDRAM 750 GB Serial ATA @ 7200 rpm AMD Radeon HD 6770M Intel HD Graphics 3000 I run some pretty resource-intensive programs like Photoshop, Logic Pro, and Final Cut Pro X. Programs like iTunes, Chrome, and Transmission are almost always running too. I also do some gaming like Starcraft 2, which as some of you may now, is very demanding at high settings (when I do run SC 2 though, or other games, I shut down all other applications).

You may be thinking that if high-end performance is my main concern, a Mac Pro would be more appropriate. But this new computer however, is a CRU.

It's a long story, but Apple basically gave it to me (early xmas gift, I guess!), so I'm trying to see what I can get out of it. I know that the 2011 MBP's are capable running 16GB of RAM, and OWC offers this upgrade for a reasonable price. Now, this upgrade doesn't void warranty, correct (my cursory research shows that it does not)? Secondly, do you think this upgrade is worth it?

I know that in Logic Pro, for example, DSP plug-ins and such can eat up RAM, so I certainly wouldn't mind more resources at my disposal in that regard. As far as gaming is concerned, my understanding is that RAM upgrades will not help much, but then again, it certainly won't make it worse (By the way, do RAM upgrades increase virtual memory?). I believe that gaming performance is very often bottlenecked with the graphics card(s). Can those be upgraded on a MacBook Pro?

B) iPod touch 4th Gen 8GB, Original iPad 16GB, SDHC 4Gb Card I have been able to replicate 3 times out of 5 this glitch by following these steps. 1) Connect your iPod touch or iPad or SDHC card to your Macbook Pro. 2) Wait for iPhoto to launch. 3)Once iPhoto is launched.

Select iPhoto from the Menu bar and click EXIT iphoto. 4) Relaunch iPhoto since your iPod touch or iPad or SDHC card is still connected, iPhoto will show you device photos first.

Deselect that by:- 5) Clicking on Photos option under Library and then hovering mouse over your Photos. The glitch should show up. 6) Quit iPhoto 7) Relaunch iPhoto 8) Deselect Device photos by clicking on Photos under Library 9) Hover mouse over Library Photos. The glitch should be still present.

MacBook Pro 10.7. 5 late 2011 next upgrade Another upgrade which may come first if not already, is to RAM with an increase in total capacity. Maximum Memory 16 GB (Actual) 8 GB (Apple) Memory Slots 2 - 204-pin PC-10600 (1333 MHz) DDR3 SO-DIMM.MacBook Pro: How to remove or install memory - Apple Support An example of reputable upgrade RAM source of matching spec to Late 2011 MacBook Pro: 3MHzSDRAM Given Mavericks OS X 10.9.5 is said to no longer be available, you may wish to try your luck first with Mountain Lion 10.8.5 just in case your older computer does not like Yosemite 10.10.1. From what I understand, you'd likely pay a fee to get & use Mt Lion. That may be worth it, if the unit does not prefer Yosemite; and it may be difficult to revert to an older one after installing 10.10.

Good luck & happy computing! I have a late 2011 macbook pro, and I wanted to know if i could upgrade my graphics card and ram for better performance while gaming. I play WoW and diablo 3 and often notice lag and can only run on low settings. So my graphics are Intel HD 3000 which is integrated, and i was wondering if i could upgrade to a graphics card like AMD or nvidia. Also, would upgrading from 4 gb of ram to 8gb of ram help my performance? You cannot upgrade the graphics card on your MBP. It is soldered to the logic board.

RAM can be increased to 8 or 16 GB. The correct specifications are; 204-pin PC-10600 (1333 MHz) DDR3 SO-DIMM. The best vendors for Mac compatible RAM are OWC and Crucial.

Hi, I have a late 2011 MacBook Pro, running Yosemite with 500GB hard drive & 4 GB of RAM. I'm going to upgrade the RAM to 16GB regardless to speed things up a little. I'm a very basic level user. Mainly use it for web surfing, watching movies, downloading music etc. I don't think I want to lose the SuperDrive as I burn cd's to play in my car. Reckon an upgrade to an internal HDD should do the trick.

Looking to get 2TB at least. Can anyone recommend anything to me please & explain to me how I go about transferring data from current HDD to the new 1? Vendors to check are OWC, DataMem, and Best Buy. I would recommend Seagate, HSGT, and Toshiba. The latter now makes a 2 TB notebook sized drive you can use in that model.

I believe this is the largest capacity for a notebook drive. Adding RAM only makes it possible to run more programs concurrently.

It doesn't speed up the computer nor make games run faster. What it can do is prevent the system from having to use disk-based VM when it runs out of RAM because you are trying to run too many applications concurrently or using applications that are extremely RAM dependent.

It will improve the performance of applications that run mostly in RAM or when loading programs. I have a mid 2009 and a late 2011 MacBook Pro, they both have the latest upgrade of Lion. Neither of them can 'see' each other in AirDrop. I have reset the apple ID on both. Is there any way I can make them 'see' each other? As far as I know the older mac is compatible with AirDrop.

Thanks So by dual-signal, are you referring to 2.5Ghz/5Ghz signal? I'm pretty sure my Mac mini 2011 has that but for whatever reason I cannot send via AirDrop to the mini. The mini can see other computers like my 2010 MacBook Pro and send files to it, but not in reverse. The MBP is unable to see or send to the mini unless the mini has engaged it to send a file to MBP.

Even then it's temporary and the mini will disappear from the MBP's AirDrop radar upon completing the delivery of its file. So I'm a bit perplexed on how the Mac mini has AirDrop, can see other AirDrop computers and send files to them, but cannot be seen on other Macs to reciprocate. Hi, I have a late 2011 MacBook Pro but cant get the mirroring function to work with Apple TV. I've got the most recent Software 10.7.5 but cant see the mirroring icon or turn this on. I'm able to mirror from my Ipad but not my Mac, any thoughts? Welcome to the Apple Support Communities AirPlay Mirroring is supported on your Mac, but it needs OS X Mountain Lion (10.8).

See You have two possibilities: 1. Make a backup, open App Store and purchase Mountain Lion to upgrade to this OS X.

Then, you will find the AirPlay Mirroring icon at the top right of the display, on the menu bar, or on System Preferences Displays. Keep OS X Lion and use AirParrot Both options work properly, but I recommend AirPlay Mirroring as it doesn't need a third-party program. I have a late 2011 Macbook Pro, 2.2 GHz with 8GB Ram with OS X 10.8.2 and a series of unfortunate events. When I connect the magsafe adapter to the computer, after it has been shut down completely overnight, with the lid closed, the Macbook attempts to restart. The restart fails beause the lid is closed but leaves my Macbook in an unstable state.

Unless I do a PRAM reset whenever this happens, I will have at least one random shutdown, usually within the first half hour of use after the computer restarts itself. I have also reset the SMC controller, checked the hard drive for errors and tested the memory. I have been careful to make sure that the computer shuts all of the way down before closing the lid and disconnecting power. As far as I can tell at this point, starting the computer on battery, and subsequently connecting the magsafe adapter, does not cause any problems. I never saw this behavior until I installed Mountain Lion.

Run an Apple hardware test and see if that picks up any problems. If this phenomenon is consistently repeatable, I recommend taking it to a repair facility for a diagnosis. This clearly is not normal operation. I hope that you might be still in the warrantee period.

After installing Yosemite on this late 2011 MacBook Pro it stops about a third of the way into booting up. It displays a null sign. I can boot into recovery disk, or external HD (I don't have a backup of this system, but can boot from my MacBook Air's clone) if I use option-R or just option at startup. It won't go into Safe Mode. From the ext HD I have reinstalled Yosemite on the MBP, but it still freezes mid-boot.

Disk Utility repair permissions, repair HD, zap PRAM, SMC, I've tried all of these (from reading advice here, and PM from Ogelthorpe). I have copied the Etre Report below.
