Found via #660 Even though already macOS package is not supported in 5.x series, Now macOS workflow always fails because of refreshed runner image https://github.com/fluent/fluent-package-builder/actions/runs/10105868174/job/27947051208 macos-14-arm64 20240722.3 causes failure. (failure of building jemalloc) https://github.com/fluent/fluent-package-builder/actions/runs/10091587427/job/27903442530 until version macos-14-arm64 20240714.2, it succeeds. So, disable macos.yml workflow manually, then enable it again if we support it.
