exec format error on Intel-based macOS GitHub Actions runners #25
Description
When I try to use the smctl provided by this GitHub Action in a workflow step on an Intel-based macOS runner (macos-13, macos-14, or macos-15-large) by running smctl sign, I see an error that I don't see when running it on ubuntu-latest:
fork/exec /Users/runner/hostedtoolcache/ssm-scd/latest/x64/smctl: exec format error: [no output]
This seems to indicate that the smctl binary provided to the macOS runner does not match the CPU architecture of the GitHub Actions runner. However, the log output from this action seems to suggest the tools are built for x64, which should be the same architecture as the macOS runners I mentioned:
tool is in a zip file trying to extract it /var/folders/0s/n7vblh2952l8rw5n_1hy40jm0000gn/T/DigiCert One Signing Manager Tools/smtools-mac-x64.zip
...
zip extraction complete , path is /var/folders/0s/n7vblh2952l8rw5n_1hy40jm0000gn/T/DigiCert One Signing Manager Tools/smtools-mac-x64
Tool to be downloaded and used {} and url is {} smctl-mac-x64 signingmanager/api-ui/v1/releases/noauth/smctl-mac-x64/download
Is there any way to get this working on macOS? I have a release pipeline that is designed to build for multiple platforms on one machine, and I have a constraint that I need to run the release build for macOS binaries on macOS due to Apple tooling that is only available on that platform. It would be a lot of work for me to redesign the pipeline because DigiCert code signing doesn't work properly on macOS.
