    This will probably sound odd but here it goes. Will I be able to install os x leopard on my iBook G4, processor 1.42 GHz PowerPC G4 and memory 1 GB DDR SDRAM. It is running os x 10.4.11 at the moment will I be able to upgrade?

    Thank you thecharliebot

    Yes, Snow Leopard (10.6) dropped support for PPC Macs. 10.5 (Leopard) is the last version that PPC Macs can use. Is there a feature that you're looking in Leopard? I think Tiger will run faster on your G4 then Leopard will

    Leopard is fully supported on your iBook. If you're going to upgrade, it'd be a good idea to max out your RAM to 1.5 GB. Also, remember that Leopard needs more hard disc space.

    In my experience, the only Macs that actually run better with Tiger are those that are significantly below Apple's recommended specs for Leopard.

    My wife used an iBook G4, 1.42 ghz, 1,25 gb ram and Leopard ran fine. She used this for a couple of years before I bought her an MBP so she could run current software.

    Might've just been a one-off thing. You could try again, but if it doesn't work again you can just hold the option key right after the bootup gong, and that will take you to a screen of bootable disks.

    I can't remember the last time I installed an OS without it rebooting to the installer by itself, but I'm pretty sure you should be able to access the installer from there.
