Hello all! I'm working with a non profit program with my school. We are donating computers to schools and students in need. We were given a TON Of macs, I believe they are all of the same model. I was given the task to clear and reinstall the Operating System, but it asks for an apple account ID. If I just make an account to authorize these will the account stay on the system, and will I get charged for it?? I am a poor College student that can't afford to pay any installation fees especially for 20+ Macs. It looks like I would be able to install it, aside from the apple ID problem I am facing.
