My MacBook Pro is stuck on loop at login. I type my password and after thinking prompts me for login again. I'm Very worried the hard disk is cactus and i won't be able to recover my recent work. Any ideas? (OSx 10.7.5, 15" retina, 750 Gb SSD, 16Gb RAM)

MacBook Pro (Retina, Mid 2012), Mac OS X (10.7.5)

    Try booting into your Recovery partition (hold down the Command and R keys whilst booting) and using Disk Utility to first verify and repair permissions and then verify and, if needed, repair your hard drive. If you get red text saying that the hard drive cannot be repaired, then it's time for a trip to the Apple Store.

     

    I'm hoping that you have one or more backup schemes in place?

    Well, your hard drive (flash storage) is good, at least. Here's what I would try next (before making a trip to the Apple Store or an AASP):

     

    Boot into your Recovery partition and reinstall OS X. This won't damage or erase any of your user files, etc., just give you a fresh installation of Mountain Lion. Since your hardware seems to be OK, it could be that the system has just become corrupt and reinstalling it may 'fix' the problem.

     

    Call back if that doesn't work...

    Not sure if you have done the mentioned steps.  I would try resetting the PRAM before doing a reinstall.  Power the machine while holding:

     

    command+option+p+r

     

    Wait for the initial chime.  When it chimes a second time you can release the keys.  Hopfully this helps.
