Microsoft AU Daemon (also called Microsoft AutoUpdate) is the automatic updater service that ships with all Microsoft Office products on macOS, including Word, Excel, PowerPoint, Outlook, Teams, OneNote, and other Microsoft applications. It runs as a background LaunchAgent that checks for and installs security updates and feature releases for Microsoft's suite, ensuring that Office apps remain current and secure. A native Apple Silicon build of this daemon has been confirmed running on Macs in the Rosetta Check community.
AI Recommendation
1 suggestionThis is not a standalone app you update separately — it is a component of Microsoft Office. The native build of Microsoft AU Daemon ships automatically as part of any native Apple Silicon build of Microsoft Office (Word, Excel, PowerPoint, Outlook, etc.). If you have a native Office app installed, the daemon is already native. If your Office apps are still Intel-only, simply launch Microsoft AutoUpdate (which you can find via Spotlight search, or by opening any Office app and going to Help → Check for Updates). Let it pull the current native build; the process takes just a few minutes. Alternatively, you can download the latest Office installer directly from microsoft.com/microsoft-365 — the download page automatically serves the native Universal Binary to M-series Macs, so you do not need to choose an architecture. After installing, the daemon will update itself automatically whenever new Office releases ship.
