Does Mac OS X Snow Leopard officially support SSD TRIM yet? If not, is there an expected availability? Also, is there a brand of SSD that is most compatible with a late-2009 Mac Pro?

TRIM is officially support with the latest build of 10.6 on Apple supplied SSDs only, i.e. not on an after-market SSD.

Is there a link to a support article for this? – Mark Richman Jun 13 '11 at 16:36
There was lots of stuff about it on macnn and macrumors when the last Air's came out. – Chopper3 Jun 13 '11 at 16:41

From Wikipedia, referencing this hack:

TRIM can be unofficially enabled on Mac OS X Snow Leopard by modifying extensions. Since February 2011 MacBook Pro models that ship with Intel SSDs are supported by Apple and feature TRIM support. Reinstalling the OS disables TRIM by default. It can be re-enabled by 3rd party software. By modifying extensions TRIM feature can be patched to support third-party SSDs and installed on other Macs

Thanks, but I was looking for official support from Apple. I've modified my question to reflect this. That hack looks very useful though! – Mark Richman Jun 13 '11 at 15:55
