Sparkle updates on macOS 14 Sonoma
NotNotch’s deployment target is macOS 14, so Sparkle updates is built to run on Sonoma and later. Appcast.xml and DMG files are served from the same NotNotch origin as the site.

Why Sonoma is the floor
The SwiftUI notch host and several system APIs assume macOS 14. Sparkle updates follows that floor.
Later systems
The same Sparkle updates path is intended to keep working through macOS 27 without bumping the minimum.
