The key insight is that Homebrew libraries on each macOS version are
compiled for that specific version:
- macOS 13: Libraries require macOS 13.0 minimum
- macOS 14: Libraries require macOS 14.0 minimum
- macOS 15: Libraries require macOS 15.0 minimum
We cannot build wheels for older macOS versions than what the bundled
Homebrew libraries require. This means:
- macOS 13 runners: Build for macOS 13.0+ (HNSW) and 13.3+ (DiskANN)
- macOS 14 runners: Build for macOS 14.0+
- macOS 15 runners: Build for macOS 15.0+
This ensures delocate-wheel succeeds by matching deployment targets
with the actual minimum versions required by system libraries.
