there is no reason to think it would be a long timeframe given their history with similar transitions

Apple already supports devices on different chips (Intel on laptops, ARM on iOS). There is nothing strange about them keeping laptops with different processors, depending on the intended use.

As I said before, the article states expressly that they're moving everything:

> Like it did then, the company plans to eventually transition the entire Mac lineup to its Arm-based processors, including the priciest desktop computers, the people said.

It's not just the hardware, it the third party software too.

If the hardware is available but you can't run the usual software no one is going to buy that. this is what I meant.

The hardware might be announced but it might not come until a decent enough number of key apps are ported.

X86-64 is the 64-bit version of x86, also known as AMD 64 and Intel 64. The first computers that apple shipped with Intel processors only supported x86 (32-bit). The most recent version of macOS removed support for x86, only allowing 64-bit apps to run. https://en.wikipedia.org/wiki/X86-64

Yes, but what is what is x86-66?

A typo

What’s the server adoption of ARM? Apple switched to x86 in the first place because it had become a standard. Adopting a common standard is always going to have advantages. The advantages of supporting or adopting ARM has to outweigh those advantages to be worthwhile. This is true not just for Apple but for the server market as well. For Apple, there are two clear advantages: power efficiency (which is the same thing…

My comment wasn't really related to macs; imo if you ship binaries you should aim to provide builds for, say, the top 3 arches, and this is especially relevant for Docker images since the de facto standard for deploying them is just to pull them from dockerhub. Docker also fails in this regard since even though it knows the arch (it says it on dockerhub) docker client will still happily pull an amd64 image on ARM wit…

Right, what I’m saying is that until there’s a lot of movement in the server space away from amd64, I can completely understand why multiarch support isn’t a priority. It’s less of a fundamental principle and more of a tradeoff.
