I doubt there would ever be parity but it could be good enough.
Have to hand it Apple OS team, they know how to squeeze a lot out of there hardware.
A while back I was trying to get an old G5 running and looking at the various OS options, many said just go with MacOS 10.4 - it was the most optimized OS for the system even today. When software and hardware work together, it can be pretty cool.
I mean, for a kind of museum piece, to get the true experience of using the computer I’d agree for sure just use original OS. But if one wanted to be able to use it for most functional purposes, it’s sad how the complete lack of backcompat in MacOS makes using an old MacOS tough — which is sad because new Linux often can work surprisingly fine on the same hardware. Like, current Debian on a 2008 Core 2 Duo is a fine computer that you can browse the Web and do basic office tasks on. It was shocking to me!
As a Quad G5 owner, might I recommend OS X "Sorbet" It's an unofficial merging of OS X 10.5 with PowerPC builds of 10.6 components. Even on ancient G3's it out-performs both 10.4 and 10.5 in benchmarks
Yup get ready for the Mac Pro that was on sale at full price until a few weeks ago at $7000 to be removed from the compatibility list for whatever comes after Sonoma.
Yes but to be fair there haven't been a lot of ppc64 machines apart from Apple's G5 desktops.
And the same is true for Apple Silicon.
If you are basically the only one to use some piece of hardware (and you are the one who designed it) your software will be the most optimized out there almost by definition.
This is to say that the focus is on the decision to customize heavily your hardware. Once you decide that it's a pretty low bar to say that your software is the best there is for running on that hardware.
