After what feels like a solid month of front pages cooing over the new hardware, a little counterbalance really could not hurt. I'm no longer an Apple hardware user, so this post (along with your comment) was the first time I'd heard AVX was unsupported. Pretty sure I'm not alone.

[edit: this seemed like quite an uncontroversial thing to say, please understand it was not intended to hurt anyone's feelings. I was a mac user for 12 years and simply don't click those links any more. Please don't downvote comments just because you're a Mac user]

They did mention it a lot (though they said a lot of things, so easy to overlook).

The actual issue is that Rosetta identifies itself as a CPU without AVX so it’s clearly a homebrew bug. And in fact if you tell homebrew not to download a prebuilt binary it works fine.

Counterbalance? The Homebrew team made a lazy assumption and it bit them. That's hardly Apple's fault.
