My daughter received an older macbook from a friend. Its running slowly and has the friend's (x) wife's stuff on it. If she resets the computer using the software.... will she be able to use it? its a model a1181. See attached label from box (She has the original box, charger, disks etc). She just needs it for office type software and internet. Nothing heavy duty. Suggestions? SHe is just out of college... has no job yet, and needs this for job acquisition stuff. THANKS!!!!
