In addition to Linux and Windows (since 20), the TRIM command is also supported under macOS (since 2011) to improve storage management on SSD hard drives. Using the TRIM command, the system informs the medium that these and those blocks of the memory are no longer required and can be overwritten.

Within the operating system (macOS, Mac OS X, Windows, Linux) the file system driver is responsible for sending the command and the memory information to the memory controller. TRIM is the name of a command that marks invalid and unused data blocks on a storage medium so that they can be rewritten.

With “Trimforce”, Apple provides an in-house command in the macOS operating system to activate TRIM on the Mac SSD - even if it comes from a third-party manufacturer. Activate TRIM command under macOS: Here's how!

Since the activation of the TRIM command changes the communication of the internal memory management of the Mac and the memory management itself is reorganized (explanation see below), a backup before the procedure cannot hurt.

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. 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.

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.
