MacBook Air on macOS 27
NotNotch is meant to run MacBook Air on macOS 27 (Darwin 27) while still supporting macOS 14. Air models with a notch get the same closed-notch live activities as Pro machines.

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
MacBook Air should keep the same user-facing behavior. Air models with a notch get the same closed-notch live activities as Pro machines.
