I have a bunch of old MacBooks (A1181 model) that we purchased from a school auction. We are trying to clean them off to donate to a local church, but have run into a bit of an issue that I haven't seen before.
The school had these locked down pretty tight. My thoughts were to wipe the system and reinstall OS X fresh, but I can't. It won't boot off the DVD and install. So I thought, "OK, I'll reset the init sequence and just reset them up from scratch like they just came out of the box." But I can't get in to delete the file in Single User Mode via - rm /var/db/.AppleSetupDone.
When I get into Single User Mode I see a "Key:" prompt. When I type nothing echos which leads me to believe this may be a password of some sort... if so, how can I reset it? I'm pretty good with Macs, but I've not seen this before. Can anyone shed any insight on this?
Thanks in advance for any help you might be able to offer.
