Apple switch to unix on ppc before switch to x86.

Well, no - NeXTstep was already x86, as was Rhapsody - the work-in-progress name of the OS, all the way up to the release of the OS under name of OSX (OS 10), which happened when Apple were done porting everything to (legacy) PowerPC. After that, OSX was on PowerPC for just a short period (6 years?) before Apple went back to x86 again (no more need for legacy Os9 compatibility “layer” (BlueBox))

You can bet your butt that Apple made sure that OSX kept working on x86 as well through those years.

Moving to ARM is a lot less hassle…
* “same endian” simplifies emulation layer
* Apple has been using ARM since the 80s, they know it well
* Darwin on ARM has been around for at least 13 years, commercially

Which is simply false: compatibility with MacOS applications was kept in the first years, even after the transition so MacOS X / Unix:
https://en.wikipedia.org/wiki/List_of_macOS_components#Classic
The Classic Environment, usually referred to as Classic, is a hardware and software abstraction layer in PowerPC versions of Mac OS X that allows most legacy applications compatible with Mac OS 9 to run on Mac OS X.

As usual, you have no clue at all of what you're talking about!

LOL. You also have no clue about coding. Is there something of which you really have some knowledge?

Of course, yes: this is possible even WITHOUT tests.

Not possible without source and binary compatibility with 68k apps.

Which, as I've already said, AROS HAS from years now!

Again, you're talking about things that you no clue at all.

AROS' Zune isn't 100% MUI compatible, but it's largely compatible. So, it's working.

If you want to have 100% MUI compatibility on 68K you can just use the regular MUI libraries, and you have it. And that's simply because AROS 68K is source AND binary compatibile with the old Amiga o.s., so you can mix AROS and Amiga o.s. libraries and/or applications.

Of course AmigaOS 4 was meant to provide an alternative to other ("modern") OSes, that's the sole reason the project was started 20 years ago. This whole "it's just a hobby!" and "support the Amiga!" nonsense was invented later, after the original project had failed to reach its goal. Which is why the sales pitch for OS4 these days is: "it's not useful at all for getting work done, so we decided to only sell it bundled with this super-expensive desktop Workstation".

The hardware dongle...
