If you’re not sure, after an upgrade simply check System Information to ensure TRIM is enabled. You can confirm this by checking your System Information application and looking at the Serial-ATA entry for your SSD:īased on this information available you will need to restart and run Trim Enabler again if you upgrade OS X to the next point release. Once this is done you will need to reboot your Mac and TRIM will be enabled.

Download and install it from the provided DMG and then flip the main toggle button to On. You can however turn on TRIM support through a series of Terminal commands and script execution or by using a free utility called Trim Enabler. You restart your Mac every couple of weeks, holding down the Option key during the reboot, then let it sit at the boot menu for 24 hours as the firmware cleans the SSD. Crucial told me I had two options: occasionally "clean" the SSD or enable the operating system to send TRIM commands to the drive. I contacted Crucial technical support to ask if the Crucial 512GB M4 SSD I purchased supported TRIM. This is something you’ll want to address. The bottom line is that without TRIM enabled the performance of an SSD will suffer over time. There is some great information on it on Wikipedia’s TRIM entry. TRIM is effectively a garbage collection model for SSDs. Derek brought up the issue in the comments and I spent some time investigating it. After adding a 3rd party SSD to your Mac, you need to investigate TRIM support.Hat tip to Eytan for pointing this out to me. At 820MB/s it is over 5 times faster than the SSD I just installed.
Though quite a bit more expensive than a standard SSD, if you want the absolute best performance for a Mac Pro you may want to consider it.
