    This would be a good time to reformat the HDD and reinstall the operating system, much safer then trying to cherry-pic what you think should be deleted.

    What version on OS X are you running? If it is modern version then you might have Recovery partition you could remote from, or us the Mac so old it doesn't doesn't have a backup at least?

    If your Mac is 2010 model or newer, then you would have the capability to reinstall over internet connection (Internet Recovery), or you will probably have a recovery partition already on your system. Any Mac running OS X 10.7 or newer will likely let you do that.

    Try starting your computer while pressing "Shift-Option-Command-R" and see where it gets you.

    I can do that in 3 steps:
    Boot to your recovery system (restart, while holding Command-R)
    Run Disk Utility (it will be either on the menu screen, or will be in the Utilities menu), and erase the drive.
    Quit Disk Utility, which will return you to the menu screen.
    And, finally, reinstall OS X. Choose your erased drive for the destination.
    When the reinstall is complete, you will boot to the new user setup. You can choose then to shut down your MBPro.
    The new owner can finish that setup.

    Sorry, that was more than 3 steps :D - but here's the short list.
    Erase the internal drive from the recovery system
    Reinstall OS X, again from the recovery system. Shut down at the new user setup screen.

    (You will need to be attached to an internet connection to reinstall OS X using the Recovery system.)
