On my Macbook Pro (mid 2010), I just had to replace the hard drive and restore from a Time Machine Backup. That part's done, but now I hit another pair hurdles. One, I can only boot in safe mode, as otherwise it goes to a blank blue screen forever. When I do boot in safe mode... the password (which I wrote down and remember clearly) won't work. I tried the password reset trick in single-user mode, no luck. Is there any way to fix this? I have a Time Machine backup drive, is there anything I can do?
