• I ran brew doctor, fixed as many issues as possible and retried my command.
• I have checked the instructions for reporting bugs.
• I made doubly sure this is not a checksum does not match error.

Description of issue

On ARM64 MacOS, brew switched to the ARM64 version of Julia 1.7.
Unfortunately, this is still not supported (Tier 3).

@dodoplus Thank you for the report - I can see as per the 1.7 post, that the ARM build is still experimental, despite being available on the downloads page. We will get this reverted.

We usually try to install native versions of software -- even when this is experimental -- on ARM. This is at least partly because we have no guarantee that a user even has Rosetta installed on ARM. So I'm personally against reverting the change.

If a user wants the Intel version, they can use a /usr/local installation of Homebrew. (Or download the .dmg themselves/use their own tap, etc.)

x86 binary was installed for Julia 1.6.4, so this seems like a breaking change.
ARM64 Julia is (unfortunately) still unusable.

This sounds like an exaggeration, given

The Julia User & Developer Survey 2021 showed that 5% of Julia users were already running Julia on this platform before an official stable version for it was released!

I don't mind adding caveats to the Julia cask for ARM that point out is an experimental ARM version. We've done the same for formulae.

Reverting the change also means that users who want the ARM version have no option to install it via Homebrew. If we keep it as is, users who want the Rosetta version have an option: use a /usr/local installation of Homebrew.
