AMD can't transfer the x86 license as per the contract that they have with Intel.
I think those of you who want ARM Macs look at it wrong. Even if Apple could get its hands on x86 license somehow, why go through all the trouble, costs and risks? Designing a hybrid ARM-x86 CPU is an insane task. A big part of the ARM-design being so successful in terms of performance gains year over year is because it isn’t x86.
Now, let’s think for a moment here. The biggest issue with an ARM Mac would be its inability to run Windows, be it via Boot Camp or VMs like Parallels. That is a HUGE problem for a lot of current Mac users. Please don’t forget that many switched to Mac because if the need arise, they’d still have access to Windows.
To overcome that problem, they are likely to create an ARM Mac and add a Intel-SoC inside to take care of the x86 compatibility. Since performance would not be the primary concern, they could use the cheaper Intel parts.
I wouldn't actually the first time Apple did something along these lines. I have an PowerMac here that has a 486-PC on a board
As usual, with this approach the gamers would be screwed, but when was the last time Apple actually thought seriously about games on the Mac? Oh yes, that was around the time of the original Hello Again event, wasn’t it?
ARM Macs and software? If Apple just ports their own software to it, I’d guess most of their current target customers would have their needs covered. So an entry 'ARM only' Mac wouldn't be out of the question either. Not now obviously, but soon(TM).
