![]() ![]() ![]() We’ve enabled it on a pair of older Macs in the Orbiting HQ with aftermarket SSDs in them, and so far we’ve had no issues-giant scary warning notwithstanding. Called trimforce, the utility can be executed from the OS X terminal, and it requires a reboot to start working. According to OS X Daily, TRIM is enabled for all Apple SSDs, but not for third party drives.The article claims that a third party utility, Trim Enabler, turns on TRIM for third party drives as well.More details can be found on the developers page.Note that this utility isnt officially supported by Apple, so you should back up before installing the utility. With today’s OS X 10.10.4 update, however, Apple has added a command line utility that can be used to enable TRIM on third-party SSDs without having to download and install anything. If you took a Mac that originally came with a spinning disk and installed an aftermarket SSD in it yourself, the operating system wouldn’t use TRIM on the disk-at least, not unless you resorted to third-party tools. The lone exception to that list has been Apple’s OS X, which-at least until today-only supported TRIM on its OEM SSDs. 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. Pretty much every operating system in use these days supports TRIM-a special ATA command that the OS sends along to an SSD when deleting files on that SSD.
