battery on macOS 27
NotNotch is meant to run battery on macOS 27 (Darwin 27) while still supporting macOS 14. Battery can appear as a short HUD rather than a permanent live activity.

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
battery should keep the same user-facing behavior. Battery can appear as a short HUD rather than a permanent live activity.
