Mac OS X 10.6.8 Brings TRIM Support for Apple SSDs, Graphics Improvements [Updated]

One item of interest regarding last week's Mac OS X 10.6.8 update reveals that Apple has enabled TRIM support retroactively for solid state hard drives shipped in Apple-produced configurations. TRIM is a feature that allows solid state drives (SSDs) to automatically handle garbage collection, cleaning up unused blocks of data and preparing them for rewriting, thereby preventing slowdowns that would otherwise occur over time as garbage data accumulates.

Support for TRIM has been included in OS X Lion since its early developer builds, but Apple has apparently decided to push the feature out to Snow Leopard users as well. The new native TRIM support does appear to limited to stock Apple drives, as users who have installed third-party SSDs into their machines have reported that TRIM is not enabled by the update.

Mac OS X 10.6.8 also appears to have brought graphics improvements that have been most apparent to gamers. According to one set of benchmarks, Mac OS X 10.6.8 outperforms Mac OS X 10.6.7 in many measure of graphics performance, sometimes by a significant margin.

User reports in the MacRumors forums and the Steam forums similarly point to significant improvements in graphics performance under real-world conditions. A number of users has actually reported significant declines in graphics performance with Mac OS X 10.6.7, so improvements with the new Mac OS X 10.6.8 are certainly to be welcome.

Update: To clarify Apple's TRIM support, the new MacBook Pros released in February shipped with a special build of Mac OS X 10.6.6 that included TRIM support for Apple SSDs. But that TRIM support had not been extended to all SSD-configurable Macs until the release of Mac OS X 10.6.8 last week.

Update 2: A number of users of pre-"Late 2010" MacBook Air models have reported that Mac OS X 10.6.8 does not enable TRIM on their machines.

Apple is not in the business of writing firmware for every storage vendor's devices. Apple has created support for TRIM in the operating system. Get on your device's manufacturer's case for adding support for it in OS X.

Windows 7 supports TRIM on a wide range of SSDs, and there are third party hacks that enable TRIM on any SSD where the firmware supports it (which is almost every drive shipped now). It wouldn't be difficult for Apple to do the same.

What if they are? If you want a file, don't delete it.
No offense, but why would you want to recover a deleted file? I mean you already have the option to recover it from the trash... If you delete it from the trash then you probably don't need it at all (or you should have thought better)

No offense, but you're putting a lot of words into his mouth. He just asked if it made deleted files unrecoverable more quickly. For all we know, he might consider that a GOOD thing. I know I do. :)

TRIM is a standard ATA feature, similar to SATA 6G. There's no need for Apple to write firmware or drivers for anyone in order to support it. Either a SSD has the capability (which will be announced to the OS if it asks nicely), or it doesn't. In the latter case, it won't work on Windows or with TRIM Enabler either. Apple has just decided not to enable it on other drives for political reasons. There's no technical reason. Windows supports TRIM generally, so could OS X.

Don't care for TRIM support unless its for Intel, OCZ and other superior third party SSD drives. Apple's toshiba rebranded drives are a joke.

What is their excuse for not supporting other drives?

Did anyone try the trim enabler application on 10.6.8 with third party SSD?

edit: nevermind, a new version was released by the author (http://www.groths.org/)
edit2: just applied the trim enabler and it is working now on 10.6.8
