## Manual Intel Mac test plan

CI currently includes `macos-13` (Intel). When GitHub announces its
deprecation, CI transitions to Apple Silicon only and Intel coverage moves to
the manual test plan below. **Do not act on this until GitHub announces the
deprecation** (spec §12).

<!-- TODO: manual Intel Mac test steps. -->
GitHub has retired the `macos-13` (Intel) hosted runners, so CI now runs on
Apple Silicon (`macos-14`) only. Those jobs sat queued indefinitely waiting
for an Intel runner that no longer exists, so they were dropped from the
matrix (spec §12). Intel-Mac coverage is therefore manual, run on an Intel Mac
before a release:

1. Create a clean virtual environment and install per the **Linux/macOS**
steps in `docs/developer.md` (numpy first, then PyNEC with
`--no-build-isolation`).
2. Run the test suite: `QT_QPA_PLATFORM=offscreen pytest`.
3. Launch the app, solve a dipole, and export a build sheet — confirming the
PySide6 UI, the PyNEC build, and the PDF backend all work on Intel.
