Calendar
Calendar on macOS 27
NotNotch is meant to run Calendar on macOS 27 (Darwin 27) while still supporting macOS 14. Upcoming events and reminders stay glanceable at the top edge.

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
Calendar should keep the same user-facing behavior. Upcoming events and reminders stay glanceable at the top edge.
