Reminders on macOS 27
NotNotch is meant to run Reminders on macOS 27 (Darwin 27) while still supporting macOS 14. Reminders can appear beside events so the next action is visible.

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
Reminders should keep the same user-facing behavior. Reminders can appear beside events so the next action is visible.
