Now, the good news we want to share with you today is that Apple has finally decided it was time to give people what they want, so they’ve added the 'trimforce' command that lets users enable TRIM support on third-party SSD disk drives on the recently released Mac OS X 10.10.4 (Yosemite) update. Probably few of you know that OS X was the only operating system that did not offer support for the TRIM function in SSD (Solid State Drive) disk drives that the user installed at some point in time after buying a Macintosh computer.Īpple offered TRIM support only for the SSD disks that came with the respective Macbook Pro or iMac computer, and until today, users had to rely on all sorts of applications, such as Trim Enabler, to unlock TRIM support for other SSDs as well. Note that no downloads of TRIM Enabler are hosted here.Last month, when Apple unveiled the upcoming Mac OS X 10.11 El Capitan operating system, some who had access to the first Beta build discovered that it introduces a new command-line that allows users to enable TRIM support on third-party SSD disks.

You can get it from the Wayback Machine instead: Download TRIM Enabler 2.2 from The Internet ArchiveĪpple 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. This can improve the performance of your Mac, as well as extend the life of your SSD. It is a utility that enables the trim feature on your Mac’s solid state drive (SSD). 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. I’m sharing this link to the old software to help fellow aging Mac enthusiasts out.ġ0.6 10.6.8 2.2 2006 Apple iMac Mac Mac Mini Mac OS X OS X Snow Leopard TRIM TRIM Enabler Post navigation Then I scanned the Internet Archive’s Wayback Machine and found a working DMG for TRIM Enabler 2.2 in there.

TRIM is critical for SSD health over time. TRIM tells the SSD that data in a block is no longer needed. Without TRIM, the drive can’t clean itself up internally because it has to assume that any block which was written is still needed, and depending on the amount of over-provisioning in the drive, you could end up in trouble without TRIM. Flash memory doesn’t work like a normal disk it can be written in “pages” (small, i.e. 4KB) but can only be erased in “blocks” (a set of many pages, i.e. It is common for a flash block to end up with some pages used and others free, and the drive tries to get ahead of user demand by garbage collecting (consolidating) these partially filled blocks into a smaller number of blocks (that have a lot more data per block), then erasing the newly freed blocks so they’re ready to go if a big burst of disk writes comes in. TRIM is how the OS says “I’m not using this data anymore, so you can mark it as free,” so getting TRIMmed is a vital component of the SSD’s garbage collection system, not just a nice-to-have feature that magically speeds things up.
