Hey guys! Long time member just don't get to post so often Just picked up a macbook for my daughter it's a 1.8 with 2 gig memory and a 250 g hd I think its first gen second revision? Anyhow... it came installed with 10.6.6 I just tried installing CS5 for her and it's not working? wants a password. In the system pref menu it says there is no master password set? I tried just hitting enter but it still wants a password. The laptop came with Tiger CD's, if I boot off the Cd's to reset the password will it affect our Snow Leopard? Thanks guys!
