Could someone please point me in the right direction. I bought another laptop for my girl so I could use her MAC for work. So I followed thread instructions and removed the applesetupdone from the unit, now the Mac just loops at the spinning gear screen. When I put in the Mac OS software it stay's on the spinning gear 4 ever. I can still log on in single user mode, but I have no idea what to do. I've been searching threds for 3 days and If I cant find an answer I guess Imma have to take it into the Apple Store if a solution is not know for this problem. 🙁
