Ok, so I'm an idiot. I wanted to refresh my MacBook pro. Spoke to a friend and didn't listen properly. Two days went by and I decided to follow the instructions he gave me Instead of formatting my harddrive to remove everything off it and still have a working mac I... Reinstalled osx lion (already have it as my os) When it booted realised my files were still there Then I formatted my harddrive And attempted to reinstall lion (god knows why ...) It failed Tried the same thing again It failed, it got to 48 minutes remaining and switched to 5 hour and 47 remaining. I left it for 6 hours with no movement or change. So I thought I'd install snow leopard os, and redownload lion from th app store, apparently my harddrive didn't like snow leopard anymore and wouldn't let me install to my harddrive with a weird error message. So I finally come to my senses and restore my time machine backup 100% successfully, computer restarts... Two hours later I'm still at the apple loading screen... I know this is a ridiculously long post, and I know I'm ridiculously stupid, please anyone, HELP?!
