    IMac g4 os 9.1 installation issues
    Hey guys. I just got an IMac g4 from my school (they upgraded, and gave me an old one) and it turns out that the OS is not installed. I dont have the original 9.1 installation disk. i just have one that they gave me with it, along with an OS 10.0 installation disk. When i try to install OS 9.1, the installation gets to the Starting Up screen, and about a quarter of the way loading, it freezes. Ive tried restarting, and that still didnt work. I have no clue what to do

    G;day and welcome to the forums.

    It depends on exactly which model iMac G4 you have. For example the very first model is capable of running OS 9.2.2 ONLY, and no earlier, together with OS X.1.3 and again no earlier. The 15" 2003 model will not install OS 9 at all, only OS X.2.3 and higher.

    Are you sure you do not have a G3 iMac, the original iMac?
    Hang on to those original install discs like grim death! Using OS X.7 or later make a bootable USB thumb drive before running Installer!

    You still have not told us what processor the iMac has. Believe it or not there are seven different models in the G4 range with all different specifications as to operating systems. Only the very first two models, 600.700MHz and 800MHz run OS 9.2.2, some of the remainder can run up to Tiger OS X.4.11 and others up to leopard OS X.5.8.

    Download a free utility called Mactracker to check them all out. Mactracker Archive Link:-

    And no you need a system install disc and without model details can't really help.
