If you don't enable your TRIM of your SSD, then you only have a jeopardized SSD. On Mac OSX, it doesn't turn on TRIM function by default for third party SSD. So you'll have to do it by yourself. But the process used to be painful, at least not enjoyable, you're instructed to run commands that you have no idea about it, and hope that it would do the magic. But now, things have changed. I present you TRIM Enabler. Just one Click, isn't it easy enough?
