Choose About this Mac from the Apple menu and check the processor.

If it's a G3, no further upgrades are available.

If it's a G4 or G5, buy a retail Mac OS X 10.5 DVD from a source such as Amazon or eBay; Apple still might have copies in stock if you phone them.

Back up your data before upgrading.

And if you want a similar computer to your G5 PowerMac, but later architecture, you

may seek to purchase an earlier version of the Mac Pro which can run much later

OS X versions than Leopard 10.5.8. While early cases are similar; they hold Intel cpu.

Your other post was moved & some details changed, as it was in an incorrect topic area.

{and in that process, errors in my reply were more apparent... it had been in iBook ASC

+ an existing reply there was also edited, to include details from mine it previously lacked.}

Other thread, modified & moved

Earlier thread your reply in above was moved from (ibook)

The early Mac Pro (intel) that can run Snow Leopard would also be able to run some

software due to the included utility Rosetta that allows certain powerPC software to run.

So that may be something to consider if you have old PPC apps. There are limits to how

this works, and the Rosetta part no longer exists for OS X after 10.6.8.

Depending on how you use a computer, there may be good reason to keep one or two

older models up and running their vintage software; some have no modern equal...

in some instances that may be a good thing if you can migrate or upgrade to newer.

Good luck & happy computing! 🙂
