Pull request overview
This pull request adds support for macOS 26 (Tahoe) Intel x64 runners and deprecates macOS 13 (Ventura) by removing all related code and configuration files. The changes enable building GitHub Actions runner images for the new macOS 26 x64 platform while cleaning up legacy support for the older macOS 13 version.
Changes:
- Added macOS 26 Intel x64 configuration to toolset-26.json including Xcode versions, development tools, and runtime environments
- Removed macOS 13 related files: toolset-13.json, macOS-13.anka.pkr.hcl template, and documentation files
- Updated helper scripts to replace Ventura OS detection with Tahoe detection functions
- Modified test files to remove PyPy and Mono tests specific to macOS 13, and updated vcpkg/Tcl-Tk test conditions
- Updated documentation (README.md, issue templates) to include macOS 26 Intel as a beta image option
- Cleaned up Parallels Desktop installation logic to exclude macOS 26 (removed from cask_packages)

images/macos/scripts/build/install-pypy.sh:1
- The removed
install-pypy.shscript previously downloaded and installed PyPy toolchains by fetchingversions.jsonand tarballs fromhttps://downloads.python.org/pypy/and then executing the unpacked binaries, all without any checksum or signature verification and with versions chosen at build time from mutable metadata. This pattern meant that a compromise of the PyPy download infrastructure or a successful network-level attack on those HTTPS requests could inject arbitrary code into the image build process, leading to a supply chain compromise of all images built with this script. Keeping this script removed, or if reintroducing similar functionality, adding explicit integrity verification (e.g., pinned hashes or signatures) and pinning to immutable versions is necessary to avoid this class of supply chain risk.

Can OSS Projects/free users use this image or is there a cost associated?? It's a regular Larger Runner. OSS projects may use our codebase to build macOS self-hosted runners. |
