Once your computer restarts, check System Report again to see if TRIM Support changed to Yes.įinally, TRIM does matter, even for modern SSDs with sophisticated garbage collection. Just open Terminal and type “sudo trimforce enable”. If it is listed but says “No”, you can try turning TRIM on by using the trimforce command in terminal. If TRIM Support is not listed, your enclosure most likely does not support TRIM. In order to check if your enclosure supports TRIM, you’ll want to go to Apple > About This Mac > System Report > Hardware > SATA/SATA Express > and look for “TRIM Support” under the enclosure specs. I used the trimforce command in terminal to enable it. Most Thunderbolt enclosures should support TRIM, and I currently have TRIM enabled on a SanDisk Extreme SSD in an Akitio Thunderbolt 2 enclosure. Firewire supposedly supports TRIM, but I haven't tested it. All five of the USB 3 enclosures / docks I have support it. The vast majority of USB enclosures do not support TRIM, but allegedly there are some that support it such as the JMS 578 USB bridge controller (source: ). However, I also have two drives in a late-2012 Mac Mini. The TRIM Enabler app is able to handle both internal and external drives, comes with various tweaks, allows you to perform benchmark tests, and allows you to monitor the S.M.A.R.T.

This question is regarding a mid-2010 MacBook Pro running macOS High Sierra. TRIM Enabler is a great tool to have around if you are using SSD with your Mac computer and you want to enable the TRIM command in order to improve its performance. (I have sources but Stack Exchange won't let me post more than 2 links)Ĭontrary to many of the comments here, the interface DOES matter. To enable TRIM, first save all your open documents as this will reboot your Mac.
Then in OS X 10.10.4, Apple introduced a “trimforce” command which enabled TRIM on 3rd party SSDs without turning off kext signing. Later, OS X 10.10 (Yosemite) introduced a security requirement called kext signing which prevented TRIM Enabler from working without completely turning off kext signing.

To get around that restriction, software such as Cindori's TRIM Enabler allowed TRIM to be used on 3rd party SSDs. Thanks a lot I did not have success using Groths Trim Enabler with 2012 MacBook Pro with Mountain Lion 10.8.2 and a Samsung SSD 840 Pro 512 GB.
Swap out for something else and TRIM gets disabled. Again, Apple supports TRIM through OS X, but only when you use one of its OEM drives. I realize this question is over 4 years old, but I'm adding a comment because this page was the first hit for a Google search on the subject and some of the comments are outdated whereas others were plain wrong.Īpple added native TRIM support in OS X 10.6.8 but only for Apple OEM SSDs.
