Hello! My kid’s Mac hard drive died so I put in a new SSD. Yay speed! It automatically installed, uh, Maverick? The one with the M. It’s an early 2011 MacBook Pro, core i5, 4GB memory.
Which is really the most recent OS that I should upgrade to on that? Sierra is hypothetically compatible, but will it be super slow?
Thanks, everyone! I went with Sierra and, with the SSD, it seems faster than ever. It was surprisingly easy – the Mac must store the wi-fi information in non-volatile memory of some sort. When I connected the new, totally blank, drive, it was still able to connect to the network.
