Mac OS X 10.6 to Get SSD TRIM Support? New MacBook Pro Suggest Yes
AppleInsider has discovered that newly released MacBook Pro 2011 updates are shipping with a unique build of Mac OS X 10.6.6 Snow Leopard that includes native TRIM support for SSD drives. Thus far the custom 10.6.6 build 10J3210 has only been reported to appear on the latest MacBook Pro models, while existing OS X 10.6.6 installations remain at build 10J567.
This information strongly suggests that Apple may release a software update to Mac OS X 10.6 that includes the native TRIM function, this would be a welcome update for Mac users with solid state drives. It is possible that TRIM could arrive with Mac OS X 10.6.7, but this is only speculation.
Update: Ethan submitted the following screenshot corroborating that SSD TRIM support is included in new versions of 10.6.6:
