Just recently, Apple started supporting TRIM in OS X Lion 10.7 Beta 1 build and also for Apple SSD’s in the new 2011 MacBook Pro’s with Snow Leopard 10.6.6 pre-loaded.
I came across this forum post on HardMac describing how to enable TRIM on third party SSD’s.
I followed the instructions and was able to get TRIM enabled for my 160GB Intel X25-M G2 SSD on my 2010 MacBook Pro. The post, however, is hard to follow, so I’ll do my best to explain how to enable TRIM on your own SSD.
