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