There never was.
This has nothing to do with setup-julia v1 vs v2.
You have some options:
- always force using the x64 build of Julia (
with: arch: x64) - don’t run macOS tests on 1.6 with aarch64 architecture
- don’t use
macos-latest(which meansmacos-14, which is Apple Silicon only) and instead usemacos-13, which runs on native Intel CPUs. This will probably stop working at some point in the future.
