Mac: With the release of OS X 10.6.8, Apple introduced TRIM support for its solid state drives that makes the drive a little faster. Apple’s operating systems don’t support non-stock drives though. Chameleon is a simple tool that allows you to speed up that third-party SSD drive.
TRIM makes your solid state drive a little faster by automatically cleaning up blocks of old data. Subsequently, with TRIM enabled, your SSD is a little quicker. Chameleon removes the lock on the driver so you can enable this feature on any SSD drive. It’s a pretty quick process that’s easy to revert if something goes wrong.
