[setup-julia] x64 arch has been requested on a macOS runner that has an arm64 (Apple Silicon) architecture. You may have meant to use the "aarch64" arch instead (or left it unspecified for the correct default).

[setup-julia] If you are testing 1.6 as a Long Term Support (lts) version, consider using the new "lts" version specifier instead of "1.6" explicitly, which will automatically resolve the current lts.

The macos-latest label will migrate to macOS 15 beginning August 4, 2025. For more information see https://github.com/actions/runner-images/issues/12520
