My late 2013 Macbook Pro Retina, running Mavericks, locked on the wheel of death during a Google search last month and shut off forever. After booting it in safe and all other modes I could think of, it was clear the ssd was toast. Not recognized. hd(0) I took it to a repair shop that claimed to repair PC's AND Macs (never mind how stupid that was) and the tech told me with absolute confidence that all I needed was a new ssd. I am now on my third aftermarket ssd installed by this guy and my macbook has shut itself down again. Replacing the ssd card is all the guy did all three times. I will be lucky to get my money back, and have already ordered a new macbook, but I am curious: has anyone else heard of this happening? Could a problem with my logic board be frying my ssds after several hours of running normally? My backup was restored from Time Machine each time, I used my legal authorization code to reactivate Office for Windows, and I ran no new apps and downloaded no new programs any of the three times I had ssd cards installed, and my repaired mac died each time within hours of getting it back from the shop. Is it worth even trying to get it repaired, again?
