If a Macbook has TRIM support, does this mean it automatically uses TRIM command on deleted files?

Under SATA/SATA Express in my System Information, I have "Yes" for TRIM support, so I assume TRIM has been enabled for my Mac. Does this mean that every time I delete a file, the TRIM command is used on those files, or do I have to invoke TRIM myself to use it?

Solution 1:

When trim is enabled you have nothing to do and the trim mechanism is operational on all ssd internal disk and external ssd in thunderbolt enclosure. For the ssd Apple you have nothing to do, Trim is enabled automatically. On other ssd you have to enable trim with the terminal command :

sudo trimforce enable
