So initially I thought that this issue was simply specific for microsoft edge but I noticed that other microsoft apps (word, excel) were also not updating properly. Now when
I open the Microsoft AutoUpdate app and there are available updates (either for edge or office apps), I will click update and the update will download but gets stuck on installing. I’ve uninstalled and reinstalled the Microsoft AutoUpdate app version 4.29
and restarted my machine but the problem remains. I can install the updates for office apps manually using the ‘update package’ link from the ‘Most current packages for Office for Mac’ but
this is both annoying to do whenever there is an update available and also not possible for edge.
To answer your question ‘Are you aware of any changes made to the computer recently?’: I have recently updated the OS to Big Sur but this issue was present on the previous OS (Catalina), and yes I tried all the troubleshooting steps in that
link.
Also I recently contacted Microsoft support and managed to get one of your representatives to view my screen to show them the problem. He recommended I create a new profile on my Mac and see if on the new profile this issue remains. It did unfortunately, and
then he was out of ideas.
