This software is the abbreviation for “Microsoft Auto-Update Daemon”, which refers to an application that runs in the background (the common term for which Daemon is used in the operating system) and performs automatic update tasks.
Here’s what happens: When you launch a Microsoft application, it checks to see if software updates are available. If this is the case, another application must be started to replace the old copy of Word with the new one; the process that does this is called “Microsoft AU Daemon”, and you see a prompt, probably because it asks your computer to change (to install the new software). As you did not launch the Microsoft AU daemon personally by double-clicking on it, macOS is careful and asks your permission before letting this application run: The operating system is pretty secure by default for these things, so you must be personally involved in everything that changes what is on your computer.
The Microsoft AU Daemon application queries Microsoft servers for updates and checks your Office product key. If you do not want to open this application and do not want to receive the command prompt every time you open an Office application, do the following.
How to disable the Microsoft daemon AU Daemon
Its impact on your system should be quite close to 0 – it works on all the Macs I’ve used in this century, and I’ve never had a problem.
If that’s what you’re saying, if you want to disable it.
1) Open System Preferences.
2) Select accounts
3) Select the connection inputs
4) Select Microsoft AU Daemon
5) Click on the “-” icon to delete it (or simply press Delete).
Microsoft AU Daemon no longer starts when you start the Office program if you disable it using the above method. It is recommended to check for updates from time to time to ensure that you receive important security updates.
