CI(release): build x64 on macos-15-intel (macos-13 runner retired)#4
Merged
Conversation
The x64 build job requested the `macos-13` runner, which GitHub retired on 2025-12-04. Jobs still targeting it are never picked up — they hang at "Waiting for a runner to pick up this job…" until the 24h queue timeout, so `build-macos.sh` never even runs. (This is a runner-availability problem, not a build-script bug.) Point the x64 job at `macos-15-intel`, GitHub's last native x86_64 image. The build stays native, so `build-macos.sh`/`bootstrap.sh` are unchanged. Caveats, documented in RELEASING.md §7: - `macos-15-intel` is a premium/large runner (bills ~2× minutes). - Intel support on Actions ends Fall 2027; after that the x64 job must cross-compile on an arm64 runner instead of building natively.

Root cause
The Build x64 job requests the
macos-13runner. GitHub retired the macos-13 Intel runner on 2025-12-04 (changelog, runner-images #13046). Jobs still targetingmacos-13are never picked up — they hang at "Waiting for a runner to pick up this job…" until the 24-hour queue timeout.That matches the observed failure (run 29137267394): the x64 job sat 3h+ with
Requested labels: macos-13and never started. Soscripts/build-macos.shnever ran — this is a runner-availability problem, not a build-script bug.Fix
Point the x64 job at
macos-15-intel— GitHub's last native x86_64 image. The build stays native, sobuild-macos.shandbootstrap.shneed no changes (they're written for native builds and already takex64as an arg)..github/workflows/release.yml— x64 matrix runnermacos-13→macos-15-inteldocs/RELEASING.md§7 — note the retirement + the two caveats belowCaveats (documented)
macos-15-intelis a premium/large runner — bills at roughly 2× minutes.VSCODE_ARCH=x64/npm_config_arch=x64, rebuild native modules for x64) instead of building natively — that will be abuild-macos.sh/bootstrap.shchange, not just a runner swap.Testing
Can't be exercised locally (needs the tagged CI build on a macOS runner). Verified the workflow YAML parses and the x64 job resolves to
macos-15-intel. The nextv*tag (orworkflow_dispatch) will confirm the runner is picked up.🤖 Generated with Claude Code
