Hi. I have a big problem. I've wanted to update my macbook pro with some app store system updates (I can't remember which) When the update began it all looked fine. But when it said "less than one minute remaning" it froze. I waited for 3-4 hours but nothing happend. I've read on several forums that other people had the same problems, and they eventually had to force shutdown the mac. So i did so too (knowing it could have potential risks). And it did. After the force shutdown, i wanted to start the mac again. The screen with the apple logo and the procesbar appeared as usual, but just before reaching half way, the screen started flickering and the mac froze again. I then tried to boot in safe mode, but i couldn't. I can boot in single user mode and in startup manager. The thing is, I have some files on the mac, which really means alot. Are there a small chance that i somehow could get those file copied to a external drive or something??? I really really hope someone can help me. It doesn't matter if the mac works afterwards, I just really want those files. Please help me.
