I have a 120 GB WD Green SSD WDS120G2G0B I would like to enable TRIM on it. I’m trying to use it in a mid 2012 13” MacBook Pro Does this SSD support TRIM in Mac-OS? And should I enable TRIM?

OSX doesn’t enable trim by default like windows does (unless the drive was preinstalled). You can enable it by typing sudo trimforce enable Into the terminal.
