TRIM support available in Mac OS X 10.6.8 update?

Several Apple fansites are reporting that the recently released Mac OS X 10.6.8 update adds TRIM support for non-third party SSDs, with screenshots as proof. Since I own a MacBook Pro with SSD built in, I was quite excited about this. However, after installing the update and restarting, System Profiler still says TRIM support is not available... My questions to the Community:
* Did anyone else have this experience? Do you have TRIM support enabled after installing 10.6.8 or not?
* Did I miss a step somewhere? Should I enable some setting manually?
Thanks in advance. Cheers!

Hi,
same same.
SSD native on a mbp Q4 2009.
I was excited to activate TRIM functionality with the 10.6.8 upgrade...no way...
I heard we still have hope with the final release 10.7
Apple, you should take care of geeks like us experiencing with SSD before all the others.
We expect you to fix the TRIM function....
Thanks,
Giovanni

Trim support not enabled

I got this MBA with SSD(251GB) a couple of weeks ago. I noticed that the "No" is shown for the Trime support. Does this mean that Apple SSD does not support Trim? Or, can that Trim support be enabled?

With the 10.6.8 update apple has added in TRIM support for stock apple oem ssd drives. 3rd party ssd drives are still s.o.l for Trim support at this time even in LION unless you use the "trim enabler" hack.
I do not advise doing so, as it has messed with a few systems, and basically could just be code that switches the "no" to a "Yes" in profiler without any actual background use.

TRIM Support in Mac SSD

I am about to purchase my first Mac and Im so excited. But before I do I have a question about the SSD. I was not planning on buying the SSD, but instead just going to some 7200RPM HDD but realized the price was only an additional $90, a price you can not just go out and buy one at.
My only concern is the lack of TRIM in Mac OSX. Now, their is speculation (and partial proof) that Lion will have TRIM support, but from what I have researched TRIM is also a hardware variable and not just software. Does anyone know if the new MacBook Pro's SSDs offer TRIM support? Also, will my SSD, by Summer hopefully, be negatively effected by the few months of the lack of TRIM?
Thank you so much,
Ben

You do not need to run any UNIX (or any other) programs to 'TRIM' the drive. If the drive firmware supports TRIM (as all newer drives do) and the operating system supports the TRIM command, you will benefit from this feature. The way TRIM works is this:
When you delete a file from a drive, the operating system marks the space used by the file as free so it can be used again. On a mechanical hard drive this works fine and the space will get written over as needed. Unfortunately, the SSD does not know the difference between erasing a block and writing over it with new data, so they are treated the same. The problem that occurs with SSD is that each block on the drive has a limited number of write cycles it can withstand before failing so the SSD firmware tries to spread out the usage of blocks on the drive by a process called wear-levelling. This ensures that the drives last as long as they need to, but results in fragmentation of the drive. This is a lower level fragmentation than what is typically referred to when discussing hard drive fragmentation and is not really related. This low level fragmentation can result in reduced performance of the drive over time, as blocks are erased and data is moved around by the wear-levelling.
The drive manufacturers have worked wonders trying to minimize this effect with intelligent firmware, but it is still a measurable problem. This is where TRIM comes into play. If the TRIM command (a low level drive command, not something you run from within the operating system) is supported throughout the system, deleting of a file will cause the operating system to issue TRIM to the SSD instead of just marking the blocks as empty as would be done on a mechanical hard disk. The SSD then knows that these blocks are no longer needed and the drive firmware can then clean up more efficiently. The drive firmware will show the space as available (because it is) but will not actually perform a write to that part of the drive until a later time, when enough blocks are ready to be TRIM'd all at once. This works in conjunction with the wear leveling to reduce wear on the flash cells and prevent fragmentation from occurring. For a more detailed description of TRIM, I recommend checking out the articles by Allyn Malventano over at PC Perspective:
http://www.pcper.com/comments.php?nid=7488
That site is mostly geared towards Windows users, but the basics of SSD operation are the same, and Allyn is definitely an expert when it comes to storage technology.
As far as over-provisioning goes, this provides a way to reduce fragmentation without the need for TRIM support (although the SandForce drives also can do TRIM). Over-provisioning involves setting aside a certain amount of flash memory on the SSD (7-28% typically) that is not available (or visible) to the operating system. The firmware uses this extra storage space to more efficiently defragment and wear-level the drive and it is transparent to the operating system. This is why an Intel X25 G2 drive will benefit more from TRIM support than a SandForce based drive like the OWC or Vertex series ones. The above mentioned site also has some good articles about over-provisioning, including comparisons of the same drive with 7% and 28% overhead. It boils down to this: if you have a SandForce drive, TRIM support is not as important because the drive does a good job on its own. If you use a different SSD, TRIM support is very beneficial, and we should all hope that OS X delivers full support for TRIM in the near future. Also, the added expense for the enterprise level (28% over-provisioned) SandForce drives is normally not justified, especially in a single drive setup.

TRIM support in Mac OSX

Hello,
I'm interested in buying a new iMac in the near future and installing an SSD, but I don't want to move forward until I receive official confirmation from Apple that Trim support will be implemented in some near-future Mac OS X update. Is anyone aware of any official word from Apple on this feature? For more info on Trim, refer to the following article:
http://www.anandtech.com/storage/showdoc.aspx?i=3531&p=10
The only word I've found from Apple is that they are "investigating Trim support", which is to non-committal for me at this time. I found that quote at the following link:
http://www.anandtech.com/storage/showdoc.aspx?i=3531&p=10
Thanks in advance for any guidance.

MacBookPro3.1 SSD and TRIM support?

Hi,
I recently replaced my HDD with an Intel X25-M (G2) 160Gb SSD drive and the mac is now _really_ fast. What I can tell from searching the net, is that the OSX operating system I'm using (10.6.4) is not yet supporting the TRIM feature of the disc. Eventually, the SSD could become slower...
Is there any information available to shed som light on this matter, such as:
a) will it be supported by Apple OSX in near future?
b) will I have to bother about it?
c) what else do I need to do in order to keep my SSD happy and fast?
Windows 7 do support TRIM and Intel provides the necessary (ToolBox) utility for Windows OS versions, but not for OSX.
Anyone?
Thanks in advance,
/Peter

I've done quite a bit of research on this subject and here's what I have come up with.
Based on anandtech's knowledge and reports, all of the Apple sold SSDs are OEM drives from either Samsung or Toshiba, and they all run custom firmware
source: http://www.anandtech.com/show/3991/apples-2010-macbook-air-11-13inch-reviewed/4
I would say that this is what's going on:
1.) Apple's SSDs run their own custom firmware and take care of drive degredation in a custom, non-industry standard way (aka TRIM) -- what a surprise, just like everything else Apple does.
2.) Apple has done this on purpose so they can make money selling SSDs for more than a standard (non Apple OEM) SSD would cost you.
3.) Apple will never implement TRIM; they want you to buy their drives with their firmware, which by all accounts, do not need TRIM and do not suffer from poor performance after extended usage.
Consider the facts -- Windows 7, Linux, BSD, [insert every other os in the world here] has supported TRIM for over a year now. It's not hard to implement; maybe 20 lines of code at the most? All it does is pass an ATA command from the SATA controller to the disk at the right times.
If you want to use a non Apple OEM SSD, I would say there's a more than likely chance it will become slower after 5-6 months of usage...Depending on the level of degredation, class of drive, how much free space is left on the drive, it could be noticeable.
Some users have reported using non Apple OEM SSDs successfully on OS X, and some have run into problems.
A few notes:
1.) A degraded drive can be reset to factory condition by using a secure erase program. You would have to back your data up, secure erase the drive, then do a restore. Secure erase of an SSD takes about 1 minute, plus the time to backup and restore depends on what kind of storage you're backing it up to \ restoring it from. This is more or less a band-aid solution for using an SSD on an OS that has no TRIM support, and should really only be done if you are experiencing problems.
2.) SLC drives are a LOT less susceptible to degredation than MLC drives. Intel still has not implemented TRIM support for the X25-e series drives...some people say that SLC drives still need TRIM, but in my experience (I've been using the SLC Intel x25-e drives for over a year and a half now), they don't. They're a lot more expensive though..by a huge margin.
3.) The less free space an SSD has, the more chance it has at becoming degraded. The obvious solution here is to store media and larger files on a NAS, and then keep only important applications and the OS on the SSD.
I hope this has helped answer some of your questions.
One more thing, according to Anand, the Kingston’s SSDNow V+ Series and the SSDNow V Series work very well on OS's without TRIM support (OS X). If I were you, I'd go with that over the Intel drive. I've never used a Gen-2 X25-M, only the Gen-1 (abandoned and discontinued by Intel, replaced with Gen-2, never had TRIM implemented and never will); and on Windows XP, I experienced stutters and slowdowns after 6 months. I used the "band-aid" solution to get the drive back to health, and then I got rid of it and picked up the 64GB V series (http://www.newegg.com/Product/Product.aspx?Item=N82E16820139132) -- unfortunately, that was around the time I switched to Windows 7, and I've never used the drive on OS X, so I can't confirm what Anand is saying; but I would take his word for it.
Since you already have the X25-M, I would keep an eye on things -- if it gets slow, back it up, do a secure erase (there's tons of programs out there, hdparm on linux is probably my favorite and the easiest to use), then a restore. Should give you another 5-6 months until you start experiencing problems again.

Minimally you need Snow Leopard or greater:
Upgrade Paths to Snow Leopard, Lion, and/or Mountain Lion
You can upgrade to Mountain Lion from Lion or directly from Snow Leopard. Mountain Lion can be downloaded from the Mac App Store for $19.99. To access the App Store you must have Snow Leopard 10.6.6 or later installed.
Upgrading to Snow Leopard
You can purchase Snow Leopard through the Apple Store: Mac OS X 10.6 Snow Leopard — Apple Store (U.S.). The price is $19.99 plus tax. You will be sent physical media by mail after placing your order.
After you install Snow Leopard you will have to download and install the Mac OS X 10.6.8 Update Combo v1.1 to update Snow Leopard to 10.6.8 and give you access to the App Store. Access to the App Store enables you to download Mountain Lion if your computer meets the requirements.
     Snow Leopard General Requirements
       1. Mac computer with an Intel processor
       2. 1GB of memory
       3. 5GB of available disk space
       4. DVD drive for installation
       5. Some features require a compatible Internet service provider;
           fees may apply.
       6. Some features require Apple’s iCloud services; fees and
           terms apply.
Upgrading to Lion
If your computer does not meet the requirements to install Mountain Lion, it may still meet the requirements to install Lion.
You can purchase Lion by contacting Customer Service: Contacting Apple for support and service — this includes international calling numbers. The cost is $19.99 (as it was before) plus tax. It's a download. You will get an email containing a redemption code that you then use at the Mac App Store to download Lion. Save a copy of that installer to your Downloads folder because the installer deletes itself at the end of the installation.
     Lion System Requirements
       1. Mac computer with an Intel Core 2 Duo, Core i3, Core i5, Core i7,
           or Xeon processor

Logic 9, SSDs, new MBPs and OSX TRIM support

Gang, my 2006 17" MBP is on its last leg, so the rumored MBP refresh is timely for me. The rumored hardware refresh has the MBPs sporting the new intel sandy bridge architecture along with a 16GB SSD boot for OSX. There's also a rumor of the option of upgrading the Superdrive to a secondary SSD.
This would've been a 50/50 coin toss a year ago as I wasn't doing audio editing/songwriting. Now, researching this whole SSD write fatigue issue is driving me nuts.
Some say that write fatigue is very real. Some say the effect is negligible in newer drives and it's getting better every few months with new hardware. Some say the write fatigue issue is moot since the poerformance is still (mostly) better than that of a HDD. Others point to it not being an issue with Win 7 and Linux due to TRIM, but it is still a bugaboo on OS X due to lack of TRIM support.
So, I'm confused.
This really wouldn't be an issue if I was running an 8 core Mac tower with 10/15k rpm drives. Since I'm updating my laptop to another laptop as my only production platform, I really want to have the best portable package I can have performance-wise (setting aside the issue of ditching the ODD for a moment).
If the rumors are true, I could boot from the dedicated SSD, have my apps, VSTs and samples on the secondary SSD, and do all my writes/reads to the HDD. Is this a logical file layout?
For those that use a SSD, what has your experience been with it in audio production? Are you SSD-only, or in a mixed SSD/HDD environment?
This is all academic really, because the first thing I'm targeting in a new MBP is 8GB of ram. My current setup is only 3GB with Logic and a major VST like Omnisphere or Trilian. I can squeak by with freezing tracks, etc. If getting opting for the SSD means losing ram, then I'm definitely passing on the upgrade.
Thanks for any input!

Mixed SSD/HD here.
I didn't really see much value in having Logic (and other apps) boot any faster since I don't mind a) boot times as they are, and b) I actually appreciate some of those times when I can't get straight to it. Sometimes slow is good, it allows the imagination free reign.
I use the SSD for all samples, etc. EG - I use Omnisphere a lot and working off a hard drive is fairly mind numbing when clicking through sounds. It's now fast enough that it begins to feel like an old school synth in terms of patch changing. I'm happy.
This way is also 'write once, read many' so I get the best of SSD tech meantime.
Irritatingly expensive for storage, of course.

What updates are available for Mac OS X 10.5.8 (9L30)?

What updates are available for Mac OS X 10.5.8 (9L30)?

Before embarking on a major OS upgrade, it would be wise, advisable and very prudent if you backup your current system to an external connected and Mac formatted Flash drive OR externally connected USB, Thunderbolt or FireWire 800, Mac formatted hard drive. Then, use either OS X Time Machine app to backup your entire system to the external drive OR purchase, install and use a data cloning app, like CarbonCopyCloner or SuperDuper, to make an exact and bootable copy (clone) of your entire Mac's internal hard drive. This step is really needed in case something goes wrong with the install of the new OS or you simply do not like the new OS, you have a very easy way/procedure to return your Mac to its former working state.
Then, determine if your Mac meets ALL minimum system install requirements.
Mac OS X v10.6 Snow Leopard system requirements
Purchased Installer disc here.
http://store.apple.com/us/product/MC573Z/A/mac-os-x-106-snow-leopard
To install Snow Leopard for the first time, you must have a Mac with:
An Intel processor
An internal or external DVD drive, or DVD or CD Sharing
At least 1 GB of RAM (additional RAM is recommended)
A built-in display or a display connected to an Apple-supplied video card supported by your computer
At least 5 GB of disk space available, or 7 GB of disk space if you install the developer tools
Installing and updating OS X 10.6 Snow Leopard to OS X 10.6.8 gives your Mac access to the Mac App Store where you can decide which version of OS X to upgrade to, again, if you desire.
OS X Lion system requirements
Purchased emailed download code here.
http://store.apple.com/us/product/MC573Z/A/mac-os-x-106-snow-leopard
To use Lion, make sure your computer has the following:
An Intel Core 2 Duo, Core i3, Core i5, Core i7, or Xeon processor
Mac OS X v10.6.6 or later to install via the Mac App Store (v10.6.8 recommended)
7 GB of available disk space
2 GB of RAM
To install OS X 10.8 Mountain Lion or OS X 10.10 Yosemite.you need one of these Macs:
OS X 10.8 Mountain Lion purchased emailed download code here.
http://store.apple.com/us/product/D6377Z/A/os-x-mountain-lion
iMac (Mid-2007 or later)
MacBook (13-inch Aluminum, Late 2008), (13-inch, Early 2009 or later)
MacBook Pro (13-inch, Mid-2009 or later),
MacBook Pro (15-inch or 17-inch, Mid/Late 2007 or later)
MacBook Air (Late 2008 or later)
Mac mini (Early 2009 or later)
Mac Pro (Early 2008 or later)
Xserve (Early 2009)
Your Mac also needs:
OS X Mountain Lion, Lion, or Snow Leopard v10.6.8 already installed
2 GB or more of memory (I strongly advise, at least, 4 GBs of RAM or more)
8 GB or more of available space.
Your year and model Mac can take a total of 6 GBs of RAM, max..
I strongly suggest you install the max. RAM your Mac can take.
Correct, compatible and reliable Mac RAM can ONLY be purchased from online RAM sources Crucial memory or OWC (macsales.com).
OWC is the only source for the 6 GB RAM kit.
Next,
If you run any older Mac software from the earlier PowerPC Macs, then none of this software will work with the newer OS X versions (10.7 and onward). OS X Snow Leopard had a magical and invisible PowerPC emulation application, called Rosetta, that worked seamlessly in the background that still allowed older PowerPC coded software to still operate in a Intel CPU Mac.
The use of Rosetta ended with OS X Snow Leopard as the Rosetta application was licensed to Apple, from a software company called Transitive, which got bought out, I believe, by IBM and Appe could no longer secure their rights to continue to use Rosetta in later versions of OS X.
So, you would need to check to see if you have software on your Mac that maybe older than, say, 2006 or older.
Also, check for app compatibilty here.
http://roaringapps.com/
If you have any commercial antivirus installed and/or hard drive cleaning apps installed on your Mac, like MacKeeper, CleanMyMac, TuneUpMyMac, MacCleanse, etc. now would be a good time to completely uninstall this apps by doing a Google search to learn how to properly uninstall these types of apps.
These types of apps will only cause your Mac issues later after the install of the new OS X version and you will have to completely uninstall these types of apps later.
Once you have determined all of this, you should be able to find the latest versions of OS X by clicking on the Mac App Store icon in the OS X Dock and then login to the Mac App Store using your Apple ID and password and using the appropriate download codes need
You can then begin the download and installation process of installing your desired versions of OS X from the Mac App Store.

I now have TRIM support. Now what?

Since updating to the most recent 10.6.8 Mac OS X update, my 2010 MBA now shows TRIM support for the first time.
There has been a lot of banter about the messageboards with many people stating that Mac SSD's do not need TRIM, because the pre-existent "garbage collection" functions are all that is needed.
I'm just wondering now that my Air has TRIM support, what has/will be improved, if anything?
Will I perceive any short term or long term benefits?
Moreover, is there anyting I need do to have TRIM perform it's magic? Or is the issuance of appropriate TRIM commands automatic and invisible to the user?

Can't turn on trim support on APPLE SSD SM128

Hello,
I'm hving problem with starting trim support on my SSD (i'm new at this ssd thingy)...as stated in the topic its an APPLE SSD SM128...
I've downloaded and started the Trim Enabler app and rebooted my computer a few times, but still i get the same msg:
"the patch is active, but the trim is not working"!
btw, im on osx 10.8.3
Does anybody know what should i do?

I bought a used late 11' Macbook Pro which came with a apple braned SSD 120gb. I took it out and popped it in my old 06' intel core 2 duo 17" Macbook pro running lion. To enable Trim I downloaded Chameleon SSD, Works GREAT!!

Ohh I bought a Samsung 840 pro 256gb and popped that in my late 11' (Mt lion) Macbook pro using Chameleon SSD Trim support on it. That too works flawlessly!!!!!!!!
Good Luck!
Keep us posted.

TRIM Support Enabler Patch

Hi Community,
I read a lot of posts the last view days which explained that the TRIM support will only work with Apple SSDs, but there are many patches available which should enable the TRIM support for those third party SSDs as well. Are those patches only fakes or are they functional? Has anyone confirmed if those patches doing there job as expected?
Thx & Bye Tom

Technically, TRIM is not supported by Lion for non-Apple-branded SSDs, but there is a work around for this.
The procedure described here worked beautifully for me: http://digitaldj.net/2011/07/21/trim-enabler-for-lion/

Question about AHCI and TRIM support in NF980a-GD65

Is it available through the chipset? I have a 780i motherboard and it's not supported on there. I'm deciding between NF980a-GD65 and 890FXA-GD65 for my Phenom II X6. The only reason I ask is that I'm planning to use a SSD. I would like to have the full ACHI and TRIM support.

TRIM is a feature of the operating system and the drive itself, not the chipset.

Apple SSD SM128 Trim support?

I have an older MacBook Air (2009 I believe) that has an Apple SSD SM128.
I'm told the latest version of Mac OS X version 10.6.8 enables TRIM support for all Apple SSD's.
I installed 10.6.8, but my system still reads "TRIM support no" when I check the System Profiler.
Does anyone know how I can get TRIM support for my SSD.
Thanks,
Sean

MacRumors reported Apple add TRIM support for Apple SSD's in 10.6.8. Am I reading something wrong?

TRIM support in Lion

I bought my mac late 2010, with a SSD harddrive. Recently I heard SSD harddrives becomes slower over time, witch is bad news in my case. But then I read Lion will have TRIM support. I cheked out my systemprofile and found out my SSD is a NVida (or soomething). Will the TRIM support in Lion only support Intels SSD? I know there are some third-party companies that offers TRIM update, but i don't trust them.
PS. I orderer my SSD thorough the apple store, I haven't built it in later.

With 10.6.8 Trim should be enabled (check System Profiler). If not you could try Trim Enabler 1.2. Also read
