Hi everyone, I need a little help please! I decided to update my MacBook Pro (late 2012) to the Public Beta, so backed up my Mac and updated it. After the update completed, my Mac was restarting and now won't switch on properly, I get stuck in a grey screen with the process bar about 75% complete which is where it stops every time. I've tried everything! So reluctantly, I booted my Mac into recovery mode and decided I was going to restore my Mac and then restore it from the backup, alas just before I did this I checked the back up and it turns out its corrupt! (Just my luck!) So what I need help with is how to get all the precious photos on my hard drive safely off and on to an external hard drive from recovery mode? Do I make an image of the hard drive or something? I just need help on the best steps to take now so I don't lose any precious photos! Thanks!
