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. Type the following command into the terminal window and press Enter:Įnter your user account’s password at the prompt.
To run trimforce, open a Terminal window (press Command + Space, type Terminal, and press Enter to launch a terminal via Spotlight). Warning: You do this at your own risk! 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.

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. RELATED: Why Solid-State Drives Slow Down As You Fill Them Up Having this operation done ahead of time improves performance.Why TRIM is Important, and Why Macs Don’t Always Enable It by Default The TRIM feature allows Windows 10, or any supported operating system, to notify an SSD which blocks of data are no longer in use and can be safely wiped out to be writable again.
The use of TRIM can improve the performance of writing data to SSDs and contribute to longer SSD life. SSD TRIM is an Advanced Technology Attachment ( ATA) command that enables an operating system to inform a NAND flash solid-state drive ( SSD) which data blocks it can erase because they are no longer in use. edit video files frequently, you'll need to trim more often.
If your SSD is mostly free space or your disk workload is light, trimming occasionally (weekly or even longer) should suffice.
Type or copy-paste the following command:fsutil behavior set disabledeletenotify 0 This will enable TRIM support for the solid state drive. To enable TRIM for SSD in Windows 10, you need to do the following: Open an elevated command prompt instance.
