fix(ci): drop x86_64 mac wheels and clean up obsolete CIBW_SKIP entries

bdraco · bdraco · commit a893676980e2 · 2026-05-16T17:28:52.000-07:00
Two issues from the 0.149.2 wheel run:

1. CIBW_ARCHS_MACOS="x86_64 arm64" failed: macos-latest is
   macos-15-arm64 and the x86_64 virtualenv was created with the
   host arch ("CPython3.10.11.final.0-64-arm64" in cibuildwheel's
   log), so the C extension built for arm64 and delocate-wheel
   refused the arch-mismatched wheel. Cross-compiling x86_64 from
   Apple Silicon is fragile enough that the simpler fix is to drop
   x86_64 mac wheels — Apple Silicon has been default since late
   2020 and Intel Mac users can still install via sdist.

2. cibuildwheel 3.x dropped Python &lt; 3.8 support and emits
   "Invalid skip selector" warnings for cp36-* cp37-* pp36-* pp37-*
   on every run. Removed.
