[Bug] macOS-latest runner is arm64, not x64

[dpo]

Description

In Tests.yml, the matrix that defines the GitHub runners to be used for CI specifies the x64 architecture for all. However, macos-latest runners are arm64.

That causes issues in repositories where additional tools, such as compilers, must be installed: the Bestie workflow installs Julia for x64 (which is allowed on arm64 macOS), but, e.g., fortran-lang/setup-fortran will install compilers for the runner’s architecture (in this case, arm64).

Package Version

latest

Julia Version

1, lts

Reproduction steps

This can only be reproduced in repos where a compiler is required.

Hi @dpo, do you have a solution for this? Can you share it? Is the repo public?
