If you're interested in the nitty-gritty, go ahead and read the Wikipedia article.Īpple started supporting TRIM since Mac OS X 10.6.8 and it's interesting that in Macs TRIM is only supported with Apple branded hard drives. Without TRIM, when your system tries to write to a part of a disk that was previously used by a file that was deleted, it has to go through a long-winded process that lasts considerably longer than if that part of your SSD was TRIMmed. Without going into too much detail it is used to let your system know which part of the hard drive is actually empty, e.g. TRIM technology has been put in place specifically for Solid State Drives. GitHub Gist: instantly share code, notes, and snippets. Some SSDs, especially newer ones, no longer require TRIM to delete their files. If you're running Mac OS X Snow Leopard, you can activate TRIM with the third-party tool Trim Enabler, which supports Mac OS X Snow Leopard 10.6.7 and higher.
Make sure you back up your SSD before applying the patch, just in case – use Carbon Copy Cloner for this task. Note that TRIM support is disabled by updating Mac OS X, so you'll need to reapply the patch again.
