Missing favorites tab in sidebar on my Mac mini

You are welcome

Restart in Safe Mode.

This will perform a Disk Repair, clear cache files and only load Apple Software, extensions and fonts.

The boot up will be slow and can take some time - Normal.

Safe Mode will also eliminate Third Party Software, extensions and drivers from loading.

It will only load the Minimum amount of Core Apple Processes to allow the the computer to function at a reduced Level of Performance 

Does the issue present in this mode ?

Sometimes a Safe Boot followed by a Normal Boot will just put things right.

Thanks.

Thank you for telling me, PRP_53 😄

There are so many things to learn about the macOS! 🙄

Much to learn, yup and still learning every day, here 😎

Welcome
