My MacBook Pro is out of space and I am trying to unload files to an external drive.  However, when I try to boot, I get the blue screen.  When I boot in safe mode, it asks for my password, then freezes.  Is there a way to move forward?  Thank you.

    There are several ways to back up a Mac that is unable to fully boot. You need an external hard drive to hold the backup data.


    1. Boot from your recovery partition (10.7 or later), a local Time Machine backup volume (10.7.2 or later), or your installation disc (10.6.8 or earlier.) Launch Disk Utility and follow the instructions in the support article linked below, under “Instructions for backing up to an external hard disk via Disk Utility.”

    2. If you have a working Mac, and both it and the non-working Mac have FireWire ports, boot the non-working Mac in target disk mode by holding down the key combination command-T at the startup chime. Connect the two Macs with a FireWire cable. The internal drive of the machine running in target mode will mount as an external drive on the other machine. Copy the data to another drive.

    3. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.

    Lion is the only OS that comes w/a recovery partition.  You need to find out from your daughter which OS is currently installed since the comp is 18 months old.

    Create a bootable data recovery / removal drive


    The object is to install OS X onto a blank powered eternal drive, then you can hold the option key to boot from it, thus allowing you to access the internal drive to remove files so OS X can boot normally from that drive again.


    Create a data recovery, undelete boot drive



    Firewire Target Disk Mode also can be used like Linc mentioned, but it requires another Mac and a cable + adapters if needed.


    A external drive is less expensive and can be gotten at any computer or office store, can be repurposed later on as a storage drive to make room off the boot drive.



    Also see this later to tune up the Mac other Tips, etc.
