Sparkle updates on macOS 27
NotNotch is meant to run Sparkle updates on macOS 27 (Darwin 27) while still supporting macOS 14. Appcast.xml and DMG files are served from the same NotNotch origin as the site.

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
Sparkle updates should keep the same user-facing behavior. Appcast.xml and DMG files are served from the same NotNotch origin as the site.
