Yes, unless they add binary translation, which would fix the first case.

uhh.. most brew shit is built from source, for which prebuilt binaries are often available. You’d just brew as usual building from source or prebuilt arm packages would be provided as usual.

> Wouldn't switching to ARM break all currently installed brew packages

(Emphasis mine.) Most Homebrew programs are not installed from source; and they'll require recompilation for the new architecture by the Homebrew team and a reinstall of all packages (to fetch the new packages) to work.

If you’re switching to an ARM Mac, it’ll be a brand new machine; there won’t be any currently installed brew packages.

Whenever I buy a new Mac, I restore from Time Machine. A few hours later my machine is exactly like the previou machine.

I think a lot of people use Migration Assistant or Time Machine when setting up a new Mac.

I've used Migration Assistant, but I don't think it carried over brew packages. Does Time Machine?
