How would I tell if I had 10.1 or 10.2 installed on a computer I am unable to log into? I guess 10.3 has the silver apple. This computer either has 10.0 10.1 or 10.2. It has a blue apple when it asks you to log in. I tried booting off of a 10.1 CD and when I tried to reset the password it says there were no users avaible. I guess that would mean it has 10.2 or the user settings are corrupted? Or would a 10.1 cd work to reset a 10.2 systems password? Or might it even be possible that this mac has 10.0?
