NotNotch is meant to run Mac Studio on macOS 27 (Darwin 27) while still supporting macOS 14. Desk setups can keep calendar and HUDs on the display you actually look at.

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
Mac Studio should keep the same user-facing behavior. Desk setups can keep calendar and HUDs on the display you actually look at.
