I don't know much about macs....

why do you need to erase it? I'm guessing there is an easier solution to your problem.

do you want to erase it so no data can be recovered?
or do you want to just delete everything and start over with a fresh OS

[kilojo999]

how do you do both, but now it wont turn on cause i kept turning it off manually.

with mac i dont have a clue
you should be able to do it with an OS install disc
