Has anyone done this? I mainly use my macbook pro for DJ'ing and writing tunes, but Ive had a couple of times now my macbook as temporarily frozen when I'm playing out. I think this is a combination of me scrolling through tracks too quick, my Macbook being 4 years old, and the stomping bass our speakers put out rattling the optical disk thats in it at the moment. Im looking for tips and advice, I'd like to do a clean install as I know this is best, but, I don't want to go through and have to find all the registration codes for all the software. I'm also not convinced I want to put yosemite on it, as it wasn't working with the dj software I used when it first came out, and the company who make the software haven't been particularly forthcoming with whether theyve sorted it out or not. So I'm thinking an SSD, an enclosure, clone the current drive to the ssd in the enclouse and then swap the drives over? Anyone else had a bash at this? I'd like to hear experiences. Also I wouldn't mind drive suggestions. I think mine currently is either 320 or 500gb, so around the same size is fine.
