When I try installing Leopard on my Powermac G4, it says that the software can't be installed. What can I do to fix it?

My current 10.4.8 version of Tiger Server running on my Powermac no longer does it for me. I had an old copy of Leopard lying around that I bought in 2008 and decided to make the iso into a bootable USB stick as my Powermac does not have a functioning DVD drive. When I booted from the drive, it said that I could not install the new operating system. It did however give me options to change passwords of my current software etc.. What can I do to fix this?

Hi!

What are the specs of your PowerMac?

If the processor speed is lower than 867MHz, the Leopard installer won't let you install the system.

Let us know!

In spite of what some Apple docs and mavens say, the majority of PowerPC Macs have difficulty booting from a USB drive of any kind. Not an issue with Intel-powered Macs.

Do you have another Mac with FireWire ports and a working drive? That can give you a viable option. Post back if you have another Mac with Firewire for instrucitons
