# Build a GEMC binary tarball natively on macOS (Apple Silicon).
2+
#
3+
# macOS has no Docker base image, so unlike the Linux Deploy/Binary Tarballs
4+
# pipeline this does NOT build/push an image. Instead it consumes the prebuilt
5+
# Geant4 macOS tarball produced by gemc/g4install's "macos_tarball" workflow,
6+
# unpacks it, downloads the Geant4 physics data, then compiles and tests GEMC
7+
# exactly as the Linux container does (via ci/build.sh). The resulting install
8+
# tree is repackaged with ci/package_install.sh into a relocatable GEMC tarball
9+
# that is attached to the rolling "dev" prerelease.
