TRIM Enabler Increases Solid State Drive Performance In OS X

TRIM is a command that lets you take advantage of your solid state drive (SSD), it isn’t available in OS X by default. TRIM Enabler patches Snow Leopard systems to take advantage of it and get better performance out of their SSDs.

TRIM support is coming in OS 10.7 Lion, but if you’re running Snow Leopard right now you can enable it with TRIM Enabler, which performs a little hack on your system that lets you take advantage of TRIM. Before you download this, you’ll want to make sure of two things:[imgclear]

  • Make sure your drive supports TRIM in the first place. You can check this by going to System Profiler and looking under Serial-ATA. Alternatively, you can Google your drive’s model number and see if it supports TRIM. If not, you don’t want to use this patch.
  • Make sure you’ve updated to 10.6.7. This won’t work on 10.6.6 or before.

Once you’ve confirmed both of those, just open up TRIM Enabler and hit the Patch button.

As always, when you’re messing with system files, I recommend making a full backup beforehand. If, after restarting, you experience any errors, booting into safe mode should help you fix the problem. Just hold down the Shift button as you boot your computer, and from there you can restore your system from a backup. For more information on the hack that’s taking place, check out this article.

I haven’t been able to test this one myself, since my SSD doesn’t actually support TRIM. So if you try this one out, let us know how it goes for you in the comments.
