I just ordered a 2012 Mac Mini core i5 2.5ghz model with a 500gb hd. I have been reading the tutorials on installing an after-market SSD and using it as the boot drive and to run apps, while using the original 500gb hd for storage. I know I can handle the install, but my question is from what I've read it sounds like after-market TRIM support has been rendered unusable with Yoseimte, unless you want to disable some security features. Can anyone advise? Thanks!
