Boring Notch upstream on macOS 27
NotNotch is meant to run Boring Notch upstream on macOS 27 (Darwin 27) while still supporting macOS 14. The Swift module and boringNotch/ tree keep upstream names so future merges stay possible.

Runtime vs SDK
Local builds may still use the macOS 26 SDK in Xcode 26. The goal is a clean run on macOS 27, not a 27-only app.
What stays the same
Boring Notch upstream should keep the same user-facing behavior. The Swift module and boringNotch/ tree keep upstream names so future merges stay possible.
