I have a early 2011 Macbook Pro and im about to rip this thing open and install some things. But before I did, I thought i should talk with people who actually know what their talking about!! Okay so I bought; OWC Data Doubler, Crucial M500 240gb, 16gb ram and 1TB external Hard drive. I didnt by a 1 TB HDD because I wasnt sure if i needed it? I have 250gb of my 320gb used right now. So if its necessary i can order HDD and wait to install at same time. So before i install do i back up with time machine on my external hard drive and then restore it to the SDD? or do the clone thing? Ive seen a bunch of install videos but not much about what to do with switching data around. My friend talked me into upgrading instead of buying a new Computer. So any help would be greatly appreciated!!
