My aged iBook G4 is currently running on OS X Tiger but it seems that I need Leopard at least in for my imminent iPhone 4S.
Does anyone have any idea as to whether I will be able to run Leopard or even Snow Leopard on my iBook? It's a 12" G4 with 1.5Gb of RAM so a decent spec for an old iBook. I have a feeling that Leopard is as new as I can go but I'm not certain and I've no idea how well it will run if I do go there.
Cheers
