The macOS image was written in M5 and never built, on the belief that the
SDK needed the paid Apple Developer Program. It does not: Xcode downloads
with a free Apple ID, and osxcross extracts the SDK from the .xip on Linux.

macOS toolchain:

  • scripts/package-macos-sdk.sh packages the SDK from an Xcode .xip in a
    throwaway container, at the osxcross commit the Dockerfile pins
  • macos.Dockerfile: clang 19, explicit osxcross "latest" flavor,
    compiler-rt for @available, asserted lipo, pinned rcodesign
  • scripts/push-macos-image.sh builds gbb-macos from the tree and pushes it
    to the private registry only; public and unqualified registries refused

Builds:

  • arch=universal (macOS only): two SCons passes, joined by lipo inside
    Godot's generate_bundle; only the bundle is collected
  • editor bundles are ad-hoc signed with rcodesign using Godot's own
    entitlements, so arm64 editors launch on Apple Silicon
  • template jobs ship Godot's macos_template.app zip (single target)
  • macOS compile failures end with custom-module hints
  • a module restricted by arch is offered to universal only if it lists
    both x86_64 and arm64
  • the Kubernetes executor refuses macOS, as it already refuses mono: its
    compile phase skips the entrypoint that configures osxcross

Also includes the mono glue-phase work: C# glue is generated in a
linuxbsd/x86_64 linux-mono container before the build container, so mono
is available on every platform, and zip moves into the base image.

Rebased onto the mono NuGet versioning fix (#16) and adapted to the glue
phase: GBB_MONO_VERSION_SUFFIX now reaches both the glue and the build
container, GODOT_VERSION_STATUS is exported at the entrypoint's top level
so packages and binary carry one version, and the --no-deprecated support
check and package-stamp check run in the glue phase. NUGET_PACKAGES stays
out of the build container, which runs no .NET.
