But there are a few outliers, and Apple doesn’t want to be responsible if your SSD’s hardware doesn’t implement TRIM properly and you run into problems.This is an updated version of an earlier post, adapted for Mac OS X 10.11 El Capitan and later. Realistically, this should work properly with most SSDs on a Mac, just as enabling TRIM works properly for most SSDs on Linux. If you want to disable trimforce and only use TRIM for Apple’s OEM solid-state drives, open a Terminal window again and run the following command: After it reboots, TRIM will be enabled for all SSDs connected to your Mac.

Your Mac will immediately reboot after you agree to the second question with a y. After you do, you’ll need to read a scary-sounding warning and agree by typing a y.

It’s always a good idea to have backups of your important files, just in case. There’s no way to enable TRIM for one SSD and leave it disabled for another. After you run it, TRIM will be enabled for all your solid-state drives. It disables the check that only allows TRIM to work with Apple-provided OEM solid-state drives. This command activates TRIM for every single SSD on your Mac. This utility is also included in OS X 10.11 El Capitan.

You may want to do some research and see what other Mac users have experienced when enabling TRIM with your SSD before continuing.Īpple quietly added a new command named “trimforce” in a minor update to OS X 10.10 Yosemite - OS X 10.10.4. Mac users have used third-party TRIM-enabling utilities for years with a variety of SSDs. You probably shouldn’t activate trimforce if you have one of the SSDs that appears on this blacklist in your Mac.īeyond that, most drives seem to work properly with TRIM on Mac OS X. In fact, the Linux kernel contains a blacklist of SSDs that don’t support TRIM properly. There have also been reports of some Crucial drives not functioning properly with TRIM on Linux. Search company Algolia found some data corruption bugs with certain Samsung SSDs with TRIM on Linux, and similar issues may occur if you enabled TRIM for such drives on a Mac. Apple doesn’t want to be responsible for any issues, which is why OS X hides this functionality behind a command and a scary warning message.Įvery solid-state drive implements TRIM in a slightly different way, and many SSD manufacturers only truly test for compatibility on Windows. Whether this is safe to do depends on the SSD you’re using in your Mac. Starting with OS X 10.10.4, Apple now provides an official - but unsupported - way of enabling TRIM for any SSD. It was now necessary to disable the kext signing security mechanism to enable TRIM for these drives, reducing a Mac’s security. As TRIM-enabling utilities worked at this low level, this locked them out.

This checks that all the drivers on a Mac are either unaltered or approved by Apple. In OS X 10.10 Yosemite, Apple introduced “kext signing” - Kernel extension signing. Users who installed their own SSDs had to hunt down third-party tools that enabled TRIM in an unsupported way. Historically, Mac OS X has only enabled TRIM for the solid-state drives Apple provides. Windows 7 and newer have had built-in support for TRIM, which they enable for all SSDs. The SSD can then manage its available storage more intelligently. TRIM ensures the physical NAND memory locations containing deleted files are erased before you need to write to them. This causes your SSD to slow down over time unless TRIM is enabled.

With flash memory, it’s faster to write to empty memory - to write to full memory, the memory must first be erased and then written to. The SSD knows that the file is deleted and it can erase the file’s data from its flash storage. When an operating system uses TRIM with a solid-state drive, it sends a signal to the SSD every time you delete a file.
