My computer won’t go past login screen, stays in loading position for forever. I went to Genius Bar and they ran tests saying everything was fine that I needed to replace the hard drive cable, so I did that and still nothing.. anyone know what’s going on?
Try restarting your system and this time go into Save Mode pressing the Shift (⇧) key Reference: Mac startup key combinations Then restart your system again if that worked. Did that fix things?
