So first off I know nothing about apple products
I have an older not sure what year it is all in one I Mac that I got second hand and everything was working fine untill I tried to factory reset it to take the other persons info off it and make me the official administrator. So upon trying this I must have done something wrong because it won't boot into IOS and instead just disc recovery, and Iam lost from there. If someone wants it that knows a little bit more than I do about apple stuff iam practically giving it away, comes with a keyboard, and I also can give you the password so your not locked out. The computer is in excellent shape, it's just old, but someone could have a nice computer if they know what they are doing.
