I know, it's old – but I had put my MacBook away cos I've got new kit and now I need it for a course I'm doing. I tried installing Sierra on it but it said it could only upgrade from 10.7 or later. Anyone know how I can get this baby's OS up to date? I figured I'd have to do in stages with a number of upgrades to current, but there are so many I could be trying & failing for hours.
