GitHub retired the
macos-12hosted runner image, so the macOS jobs in the CI matrix have been queuing forever and never running (see the stuckmacos-12jobs on recent CI runs).This pins the matrix to
macos-26, the latest stable numbered macOS image.Note:
macos-12was Intel (x86_64);macos-26runs on Apple Silicon (arm64), so macOS tests now exercise arm64 wheels/dependencies.
