Partition HD OSX 10.8

You need to do it while booted into a different disk's volume; e.g., an ext HD connected to the machine. If the MBP came with SL or earlier, use the install discs. If a later OS, use Recovery mode to erase and repartition the HD, then tell the buyer how to boot into Internet Recovery to reinstall the OS the machine shipped with. That way, they get to use their AppleID to register the machine.

Select the partition you want to erase, not the main HD.

If the HD or its volumes won't unmount, then reboot with the install disc, and see if the Terminal app is under the Utilities menu. If so, run this:

diskutil unmountDisk force /Volumes/DISK_NAME

Just replace DISK_NAME with the volume name (yes, it’s case sensitive) and hit the return key. Then, quit the Terminal app and retry Disk Utility.
