Hi all, I have recently acquired a G3 (and G4) so am getting familiar with the Mac. The G3 had 9.04 installed on it, I then updated the firmware, installed the 9.10 upgrade, and finally installed OS X 10.3 as it is the newest version operable on that particular model (M5521). My issue is that I was trying to install some games for my 3 year old that run in Classic OS yet I receive the message "Classic OS Not Installed". This may be a quick fix, but can anyone lend me some expertise? This machine is perfect for my boy to play games and educational software on!
