    Hi,

    I have a bunch of older Macs (about 10 of them) that I no longer use and would like to sell. Is there any type of software for Macs that would completely erase the harddrive so that the information cannot be retrieved?

    Thanks for your help!

    Use Disk Utility. Hook them up with a firewire cable to your current machine, boot in target disk mode. Use Disk Utility to erase the disk. I would suggest zeroing it out as well.

    But will this be a safe enough way that the new owner will not be able to find any information? I am worried because these were used for a business and have client info on them.
    Thanks.

    If you have sensitive data then I suggest investing the time to do a 35-pass zeroing out after you completely erased the volume.

    Gosh, I don't know, I've never used one, I've only heard about them.

    Well, if we're going to kill hard drives I would use a sledge hammer. ;)

    35 pass is excessive. 7 pass is what the DOD uses and suggests for eliminating critical data from your drives.
