![]() If it didn’t, or if your computer is having issues booting, boot into safe mode by holding Shift when you boot up. If you open up System Profiler (by going to /Applications/Utilities/System Profiler), hit Serial-ATA in the sidebar and choose your SSD in the topmost pane, you should notice that your drive will show “Yes” under “TRIM Support”. Once you’ve backed up, go ahead and hit “Patch”. Before you do anything, hit the “Backup” button-this will back up the kernel extension to any folder you want, so that if the patched extension doesn’t work, you can restore the old one without a problem. Once you’ve updated to 10.6.7 and verified that your SSD supports TRIM, you’re ready to roll. It’ll actually decrease your drive’s performance.įirst, make sure you’ve updated to at least Mac OS X 10.6.7, as Trim Enabler won’t work on previous versions of OS X. Unfortunately, for some reason, the Apple driver for TRIM seems to conflict with drives that have garbage collection built-in to the controller, so you won’t want to use it. TRIM and garbage collection are similar, but they are not the same thing. Your SSD already has built-in garbage collection.Also note that you might need to update your firmware to get TRIM support, and you can find instructions on how to do that on the manufacturer’s web site. So even if it says “No” in System Profiler, you should still Google your drive to see if it supports TRIM. Note that the “TRIM Support” line in System Profiler does not tell you whether TRIM is supported, only if it’s enabled. The only way to figure this out is to Google your SSD’s model number and find out if it supports TRIM. TRIM Enabler won’t work for all SSD users. Here’s how to maximize your TRIM benefits. However, it turns out there’s a little more to it than just hitting the “Patch” button. If you have a non-Apple SSD, or you just want to get TRIM support now, previously mentioned TRIM Support Enabler will do it for you. TRIM support is coming in OS 10.7 Lion, but that’s still a way off, and even then, it’ll only work with Apple SSDs. Here’s an easy way to get better performance and longevity out of your Mac’s SSD. Enabling TRIM is one of the best ways to maximise the life of your solid-state drive, but OS X doesn’t support it out-of-the-box.
