Power Mac G4 "Yikes!" - Trying to install OS X Snow Leopard onto a new hard drive

    Hello, as the title says, I am trying to install OS X Snow Leopard onto my Power G4 with a new (but partitioned) hard drive, and I am having problems. Whenever I hold "c" after hearing the power chime, it does nothing and show the flashing finder and question mark. When I hold down alt/option it just shows two buttons - one with a "refresh" arrow, and one which looks like a "next" arrow, which does nothing when I click it. Could anyone please assist me with this? Thanks in advance.

    Also, this is my first post on this forum, and I'd like to give a warm and humble hello to you all!

    It is not possible to install snow leopard on a PPC machine.

    Snow Leopard only supports Mac with Intel CPUs. It cannot be installed on a G4.

    What is the highest OS that can be installed onto it?
    (Good thing I borrowed the CD from a friend!)

    As far as I can remember, 10.4 is the newest supported version for that machine, however 10.3 may be a better choice if you have limited RAM.

    So, would that be "Tiger"?
    Sorry, this is my real first time actually using a Macintosh machine.

    Yep, 10.4 is the latest supported version. You will need at least 1GB RAM to run 10.4 well, and 1.5GB would be better (if that much is supported by that computer)

    I'm not planning on spending TOO much on this thing, but if I come into some extra money (or feel like taking an old machine apart) I'll put some new chips into it. Thanks!

    OS 10.5 can be installed on some G4 machines, depending on the processor speed. However, "LeopardAssist" can get you around those limitations.

    Having got it on my G4/450 Sawtooth I would highly recommend against installing 10.5 on anything under a 667 G4 without upgrading the Graphics. I tried it on the original Rage 128 and it is, to say the least, absolutely diabolical. (Think waiting a noticeable number of seconds to open a window with the dull dock and spotlight and a host of other things off).

    You're right about that. My sawtooth was upgraded to 1.3GHz and is just "OK" with Leopard.

    Yes. Running anything from Tiger beyond without a Quartz Extreme graphics card (Radeon/Geforce2 or better on an AGP or better bus) is really painful, as much of the graphics processing is offloaded (slowly) to the CPU, which slows down the whole system. A Yikes G4 can only do Quartz Extreme with hacked video drivers to allow QE over PCI; this still requires a Radeon/Geforce2 or better. I wouldn't go above 10.3 with the stock video card in that machine.

    Unless you have software that requires 10.4 Tiger, I'd put 10.3 Panther. Tiger needs "a lot" of RAM.
  15. macrumors newbie

    You can go to 10.5.8 Leopard. That's the highest it'll take. I have one.

    3 1/2 years after the question, but better late then never as the saying goes.

    I'd stick with Tiger. Toss in some more ram and a Radeon 9200 PCI card and you'll be on your way with a nice old Mac!

    Skip the ATI 920" and go with a GeForce 5200. It'll give you CoreImage, but you'll loose OS 9 video acceleration.
