Description

macos-latest tag now points to macos-14-arm64, under this architecture homebrew has issues installing some packages.

The following command:

brew install \
  boost \
  cmake \
  miniupnpc \
  node \
  opus \
  pkg-config

Results in:

Warning: Treating cmake as a formula. For the cask, use homebrew/cask/cmake or specify the `--cask` flag.
Warning: cmake 3.29.2 is already installed and up-to-date.
To reinstall 3.29.2, run:
  brew reinstall cmake
Warning: pkg-config 0.29.2_3 is already installed and up-to-date.
To reinstall 0.29.2_3, run:
  brew reinstall pkg-config
Error: Cannot install under Rosetta 2 in ARM default prefix (/opt/homebrew)!
To rerun under ARM use:
    arch -arm64 brew install ...
To install under x86_64, install Homebrew into /usr/local.
Error: Process completed with exit code 1.

I noticed that running uname -m returns x86_64. That seems a little fishy if the image is actually arm64.

Is it regression?

Yes. macos-12 (when it was macos-latest) https://github.com/actions/runner-images/releases/tag/macOS-12%2F20240418.1

Expected behavior

Homebrew properly detects image architecture, and uname properly reports it.

Actual behavior

Homebrew doesn't properly detect image architecture and uname doesn't properly report it.
