How to enable TRIM on macOS

Apple added a command called trimforce in Mac OS X 10.10.4, allowing Mac owners using third-party SSDs to enable TRIM. Earlier versions of OS X can use a third-party TRIM enabler utility to do the same. As your SSD fills up over time, enabling TRIM can speed up the write process.

  1. Open the Terminal from /Applications/Utilities.
  2. Type sudo trimforce enable and hit return or enter.
  3. Carefully read the important notice and if you still wish to proceed, hit Y.
  4. If you would like to disable TRIM, you can use the command sudo trimforce disable.
