This was a standard feature of Mac OS X on PowerPC hardware from the 10.0 developer builds through 10.4.

That would be a PowerMac G5. No Power Macintosh has an Intel processor.

By "1.1" do you mean the Mac Pro? The Mac Pro has always had an Intel processor, and the model code for the first Mac Pro was MacPro1,1.

This is confusing. Can you restate it or at least correct your typos before posting? There's no G3 that can run the latest macOS, since a G3 is a kind of PowerPC CPU.

Not any supported way, which is the only way I'd be allowed to discuss.
