About:
Microsoft Auto Update (MAU) is the official update manager for Microsoft 365 applications on macOS. It automatically checks for, downloads, and installs the latest security patches, bug fixes, and feature releases for apps like Word, Excel, and Teams. This ensures your Microsoft software remains secure and up-to-date with minimal user intervention.
Key Features:
  • Automatic background checks for software updates
  • Centralized management for all Microsoft 365 apps
  • Flexible configuration for deployment and user control
  • Support for both managed and unmanaged installations
Use Cases:
  • Managing update schedules for enterprise fleets of Macs
  • Keeping individual Microsoft 365 subscriptions current
  • IT administration of Office suite versions
Alternatives:
  • Homebrew – Can update casks but lacks the granular control MAU provides for Office Insider rings and specific app targeting.
  • Managed Software Center – Munki-based solution often used in enterprise to manage all software, including wrapping MAU for centralized control.
