A co-worker gave me a Mac book air to repair for her. Her son deleted some files because he forgot his password. How do I reinstall iOS to the HD. (Complication: I'm a PC guy and have very little mac experience) Oh, almost forgot, the laptop boots to the utility screen and I can get it online but can't get it fixed via that option Says there was an error. Also, Mom bought this for her son so it isn't stolen.
Thanks in Advance
