    (Original thread title: Exploding G5!)

    Greetings from New Zealand!

    I am wanting to Install other versions of OS X on my G5. It is currently running 10.4.3. Using iPartition I have created empty partitions to do this.
    I put in my Panther installation disk, and then selected it as the Startup disk but after restarting, the machine refuses to Startup from the disk, it starts whirring loudly and gives the impression that it is either about to take off or explode!

    Am l am able to install older versions of OS X?

    Why is it not letting me do it?

    Any advice, hints or tips would be greatly appreciated.

    Cheers and Merry Christmas!

    Which G5 do you have? If it post dates Panther, you probably can't run it.

    You won't be able to install an OS that is older than the version it shipped with.

    Of course, if you were really daring you could install an older version on your PMG5 through target disk mode. I ussume some things would not work right and this could possibly hurt your system as older systems like Panther will not know how to handle some system functions of the newest machines.

    i would not recommend this.

    It won't work. You can try a distribution of Linux that will work with your G5 and run Mac-on-Linux using an older copy.

    [edit] Mac-on-Linux not supported on G5 systems. Sorry.

    Sorry, but I don't think you can install an OS on your machine any older than the one it had initially installed, someone correct me if I'm wrong. Due to some components, etc., I don't think OSes such as Jaguar and Panther would know how to react and work with them.

    Usually you can't.

    But sometimes it is possible to install an earlier version (well... at least "get it running").
    One example is the Rev B iMac G5: Shipped with 10.4.0. But as all the internal components were all supported by 10.3.9, you could install 10.3.9 on it by restoring a pre-installed disk image.
    It's all unsupported ofcourse, but sometimes it can work.
