Apple added TRIM support to Mac OS X in Snow Leopard update 10.6.7, but it only works on Apple SSDs. Third party SSDs never have TRIM enabled. There is an exception: in Mac OS X 10.10.4 and later have a command you can run in a terminal called “trimforce” that will enable TRIM support for ALL SSDs, not just Apple SSDs. What do you do if you’re on an older version of OS X? Well, Apple doesn’t give you trimforce on older versions, so the only answer is to “hack” the storage driver in OS X to bypass the check.
The tool of choice to do this for several years was called TRIM Enabler, with the last version supporting OS X 10.6 “Snow Leopard” being TRIM Enabler 2.2, the holy grail of flipping the TRIM switch on older OS X versions. However, sometime in 2014, the author of TRIM Enabler made it a paid program and took away the free download for TRIM Enabler 2.2, opting to only make it available if you bought a newer version despite TRIM Enabler 2.2 being totally free to download and use. There are no other downloads of the old 2.2 version available. I’m upgrading a machine stuck on 10.6.8 and I didn’t want to pay for what was once a 100% free program.
Then I scanned the Internet Archive’s Wayback Machine and found a working DMG for TRIM Enabler 2.2 in there. I’m sharing this link to the old software to help fellow aging Mac enthusiasts out.
