I started using a MacBook Air M1, macOS Big Sur 11.2. When I created the user account I selected a lowercase name for the home directory. Later, I wanted to change that to a first uppercase name. I found and used instructions for that (log in as a different user, rename directory, modify account info to point to the right directory). All of this worked fine; I can log in without problems, all files and foldes are there.
However - in Finder, all top level folders in my home directory now have the generic folder icon. No special icons for Documents, Music, Movies, Pictures, Downloads, Desktop, Public.
How do I restore those?
Any help appreciated - thanks.
