Enable TRIM Support for a SSD in MAC OS X

TRIM support for a SSD is the best way to prolong its life. In Mac OS X, TRIM is only enabled for Apple’s SSDs. This is great if you have a new Macbook that has an Apple SSD inside of it. But for the rest of us that upgraded our old hard drives for third party SSDs we are out of luck. Luckily we can use an awesome free utility to enable TRIM Support inside Mac OS X for third party SSDs. .

What is TRIM and why Enable it?

TRIM is a command, thats right it is not an acronym, that lets the operating system  know which blocks in a solid-state drive, or SSD, that are no longer in use and can be wiped. TRIM was created to do this because of the way operating systems handle deletes and formats on SSDs, which lead to performance issues.

Before you show you how easy it is to enable TRIM support, we will first need to make sure your SSD can support TRIM, or doesn’t have its own garbage collection built in. The best way to find out is to do a quick Google search of your SSD to see if it supports TRIM.

With the help of a free tool called TRIM enabler we can quickly and easily enable TRIM. Just remember that TRIM support can be added to SSDs on Mac OS X 10.7.8 and 10.6.8. After you download TRIM enabler, links below, install the application and launch it. You will be greeted with a super simple interface. And with a flick of a switch you can enable TRIM support.

Sometimes you will need to reboot your Mac to get TRIM to work. Just reboot and relaunch TRIM enabler and see if it worked. Disabling TRIM support is really easy. Just open the TRIM enabler app and flip the switch back to OFF.
