Displays
multiple displays on macOS 27
NotNotch is meant to run multiple displays on macOS 27 (Darwin 27) while still supporting macOS 14. The companion can follow the display you choose instead of cloning every screen.

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
multiple displays should keep the same user-facing behavior. The companion can follow the display you choose instead of cloning every screen.
