macOS 27
macOS Tahoe on macOS 14 Sonoma
NotNotch’s deployment target is macOS 14, so macOS Tahoe is built to run on Sonoma and later. The current Xcode 26 toolchain still ships a macOS 26 SDK while the app is expected to run on Darwin 27.

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