Mbp stuck on responding login after update
App Store suggested to update Mountain Lion from 10.3 to 10.5 I think, so I agreed.
It logged out and restarted and started installing the update, so far so good, it finished and booted, all good so far, it took me to the gray login screen (with my admin account, my second account and a guest one) so I click on my admin account, type in my password and it takes me for less than a second to a blue screen and then back to the gray login screen! Why? What's wrong? Same with the second account and I m not sure on the guest account since I have no idea of what the password is, I'm super stucked! Is there a way to workaround ? Or do something? I didn't back up anything :(
Thanks
