TRIM SSD Support Enabled in Mac OS X 10.6.8 Update
The recently released Mac OS X 10.6.8 Software Update has quietly added native TRIM support to Macs equipped with SSD drives. TRIM insures that your SSD drive will be functioning at optimal speed and extends the life of the solid state disk, making this a must-have update for any Mac user using solid state storage.
Enabling native TRIM support on your Mac’s SSD drive is just a matter of installing the Mac OS X 10.6.8 software update and then rebooting your machine. Installing the OS X 10.6.8 update eliminates the need for the assorted third party hacks that surfaced to hack TRIM to work, so it may be a wise idea to disable those tools before installing the official update.
Mac OS X 10.7 Lion also includes TRIM support natively, and is due for a public release sometime this July.
Update: We can confirm that TRIM is enabled on Apple provided SSD’s with 10.6.8 installed, but some third party SSD’s continue to not support TRIM despite the update. Lion may address this, or you can continue to use the third party TRIM Enabler tool.
