App Sandbox on macOS 27
NotNotch is meant to run App Sandbox on macOS 27 (Darwin 27) while still supporting macOS 14. File pickers use the user-selected read-write entitlement rather than a blanket home-folder grant.

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
App Sandbox should keep the same user-facing behavior. File pickers use the user-selected read-write entitlement rather than a blanket home-folder grant.
