Pull request overview

Removes macOS Intel (amd64) coverage from the CI/release pipelines and updates the CMSIS Build installer logic to select macOS binaries by detected architecture rather than always using amd64.

Changes:

• Update installer scripts to use mac-${arch} on Darwin instead of hardcoding mac-amd64.
• Remove macOS-amd64 artifact downloads from release packaging workflows.
• Drop macos-15-intel (amd64) entries from GitHub Actions test matrices.

tools/buildmgr/cbuildgen/installer/install.sh:297

• On macOS, this now selects binaries based on ${arch}, which is good for arm64, but if macOS-amd64 support is being dropped then running the installer on an Intel Mac will silently fail to install expected binaries. Also, remove_bin ${install_dir} is unquoted and will break if the install path contains spaces.

Consider explicitly erroring out on arch==amd64 for Darwin and quote the remove_bin argument to avoid word-splitting.

  'Darwin')
    extn="mac-${arch}"
    for f in "${install_dir}"/bin/*.${extn}; do
      mv "$f" "${f%.${extn}}"
    done
    remove_bin ${install_dir}
    chmod -R +x "${install_dir}"/bin

.github/workflows/buildmgr.yml:477

• This workflow no longer runs Cbuild integration tests on macOS after removing the macos && arch==amd64 step. Since the matrix still includes macOS (macos-14, arch: arm64), the macOS jobs now build CbuildIntegTests but never execute them.

If macOS arm64 is still a supported target, add an integration-test run step for macos && arch==arm64 (similar to the previous macOS amd64 step).

      - name: Run Cbuild Integration Tests (excl. DebPkgTests, AC5, AC6, MultiTargetAC6Tests) for Windows
        if: ${{ startsWith(matrix.runs_on, 'windows') && matrix.arch == 'amd64' }}
        run: .\tools\buildmgr\test\integrationtests\${{ matrix.target }}-${{ matrix.arch }}\Debug\CbuildIntegTests.exe --gtest_filter=-*DebPkgTests*:*AC5*:*AC6*:*MultiTargetAC6Tests* --gtest_output=xml:test_reports/cbuildintegtests-report-${{ matrix.target }}-${{ matrix.arch }}.xml
