    Hey guys:

    Im brand spankin' new here, so Hi everyone!!!!! I'm not up much on anything Mac, but a friend of mine was running a Mac (mini) Mountain Lion update that failed at the very end and when she turned off the Mac and back on she's getting the big bag circle of death. I don't know how to proceed??? Any suggestions are appreciated.

    Thanks

    You can try rebuilding/ reinstalling OSX by Holding down the CMD key + R after pressing the power button which boots the maintenance menu.

    From here you can try reinstalling Mountain Lion - if she hasn't backed up her data via TimeMachine or manual backups she will lose all data though. You should always plug in a Mac before any software updates for future reference, and not manually turn it off when it hasn't completed. This will cause data corruption.

    Agreed.

    The reason for the manual "Turn off" was the mini froze up and wasn't responding at all.

    Can I put the OS on a different drive and then suck off any data she may want? I was hoping for a less offensive move.

    This is the 2nd post I've seen today that said they got the "prohibited" sign on a boot drive after Mountain Lion installed.

    If a drive is in good shape you should see it and not get the "prohibited" sign, or for that matter a folder with a question mark in it. This often means that the PRAM settings are corrupt. Why a ML install would reset or even modify them is beyond me.

    To reset the PRAM, go here:

    or here:

    http://support.apple.com/kb/PH11243

    It might work. Then again it might not. There's really no telling what the state of the system was in when it was powered off. It might have been some intensive spotlight indexing which could make the system seem like it was locked up when it wasn't.

    :eek:

    If you're feeling adventurous (and don't have another Mac nearby that you can use Target Disk Mode with), create a bootable Linux USB drive and boot your Mac from it (holding Option at boot and selecting the USB drive). You will have access to the files on the disk and can copy the files anywhere you want (e.g., another drive, network storage, etc.).

    You can find instructions on how to build an Ubuntu Linux bootable USB thumb drive on Google. It's about a 3/10 difficulty on a Windows machine and a 6/10 difficulty on another Mac.
