Nudge (macadmin's Slack #nudge)
Nudge is a multi-linguistic application, offering custom user deferrals, which strongly encourages macOS updates. Written in Swift and SwiftUI.
Nudge will only work on macOS Big Sur 11 and later and is a replacement for the original Nudge, which was written in Python 2/3. If you need to enforce macOS updates for earlier versions, it is recommended to use nudge-python.
Nudge 2.0 enables fully automated updates, by default, by querying the Simple Organized Feed for Apple Software Updates (SOFA) for macOS releases.
