How do I enable Trim on non-Apple SSD?

[Hervé]

Since Yosemite 10.10.4, OS X/macOS supports trimming for non-Apple SSD. The facility can be enabled through the following Terminal command:

sudo trimforce enable

`

For earlier versions, the IOAHCIBlockStorage kext must be binary patched to suppress whitelisting for Apple-branded SSDs only:

Find:       004150504c452053534400     (=> " APPLE SSD ")
Replace by: 0000000000000000000000     (=> "           ")

NB: this patch can also be used for Yosemite 10.10.4 and later.in

 

I believe the patch was 1st reported at InsanelyMac. It's one of the kext patches provided by default in Clover Configurator.
