Can't Login


When I get to the login screen and type in my password, the progress bar works, then the screen momentarily goes blue, then the login screen shows up again. This happens every time. I've tried restarting, shutting down and starting up, unplugging the machine, disconnecting various devices, etc. Everytime, I get the same result.

Do you have the OS CD?

Start up with the OS X CD (matching the version you are running) and do not click on the installer screen. Instead go to the Installer menu and select Disk utility.
When that opens click on the second icon in the side bar at the left, then click on Repair Disk at the bottom right.

Watch the activity screen. If it does any repairs - you will need to click on the Repair Disk button a second time after the first pass is done. The object is to make sure it finds all the problems and repairs them. You may need to hit that button a third or fourth time to get no references to repairs made.

Now click on Repair Permissions.

When that is done, quit Disk utility and restart the computer.
