10.6.8 brings more TRIM support, graphics improvements

updated 06:10 pm EDT, Mon June 27, 2011

More than 40 percent faster graphics in some tests

The release of OS X 10.6.8 has brought improvements to both gamers and those using Apple-approved models of solid-state drives (SSD), MacRumors reports. Apart from some model-specific builds of 10.6.6 and 10.6.7, OS X has generally lacked TRIM support, but as of 10.6.8 TRIM now appears to be available in all Macs capable of running it, and will also be included in Lion. The update has also brought significant graphics improvements, according to testers on Steam and other forums.

TRIM is a technology for SSD drives that enables garbage collection and write optimization, basically keeping the drive's performance at a steady level rather than allowing it to deteriorate over time. Apple's TRIM support is thus far limited to the brands of drives Apple ships or makes available as an option with models such as the MacBook Air, but unofficial TRIM support for other brands has existed since the release of Snow Leopard, but was turned off by default except on certain special builds of 10.6.6 and 10.6.7 for the MBA and other machines that were custom-built with SSDs.

Some third-party SSD resellers (such as Other World Computing) have turned to other technologies such as over-provisioning to enable TRIM-like performance sustainability on their drives, and there are other third-party programs that claim to turn on the unofficial SSD support in Snow Leopard, though some users have reported problems with these. TRIM is widely supported in Windows 7 for most major brands of SSDs.

In addition to wider TRIM support, gamers and other graphic system testers have reported that 10.6.8 has boosted graphics performance, particularly for OpenGL and user interface graphics. Testing done by MacRumors shows a significant jump in OpenGL speeds, often improving the speeds of games such as Halo (showed a 37 percent improvement). Other OpenGL tests showed around a 40 percent improvement. [via MacRumors]

    Been doing this in Windows 7 since 2009! You're only two years late to the game.

    Even a broken clock

    is right twice a day. Sadly, wrenchy, you're not even as good as broken clock. As the article states, Apple has also had TRIM support (unofficially, but reachable) since the release of Snow Leopard. Guess how long ago that was.

    Apple started turning the ability "on" once they released models that actually shipped with SSDs, and are now expanding the official support. Gosh, how logical of them!

    It's true that Windows has had wider official support of TRIM for longer, but then, they HAVE to do this, since they have to at least half-support every device on the planet (including badly-made Chinese knock-offs). It was to MS's great advantage that SSD manufacturers came up with a standard for this instead of pursuing the usual "Windows mentality," which is to come up with several dozen competing "standards" and let them all slug it out to the detriment of the consumer.

    Ballmer doesn't get any credit for that, but whoever made the early decision to support TRIM generally does deserve some credit.

    Adobe Master Suite 5.5

    Can any users comment on the upgrade and use with Adobe software?

    See any changes?

    That's only logical to a fanboy defender. To think that they needn't worry about it since they didn't release the drive is silly.

    Microsoft doesn't have to support any device. Device makers build the support through drivers (I know, it's so weird, isn't it). Microsoft has to build in support for the standard interfaces.

    And it is silly that an OS actually add support to their OS for some new hardware. Don't they know they should wait until the computer manufacturers add the drives to their computers. Then only support those drives. Then wait. Then wait. Then finally release support for third-party drives.

    That's the logical way, right?

    Wasn't that to EVERYONE's advantage? That helped Apple just as much as MS, and helped the drive makers most.

    And I like how you somehow try to blame Microsoft when peripheral makers can't come up with a standard on their own. As if it was Microsoft's place to do that (and, I'm sure, if they did try to set a standard, you'd slam them for using their might to do things the way MS wants it).
