When I updated to Catalina, the update added several "empty" folders to my computer that are part of the Wheel group. Most of them are named for previously attached external drives: Seagate 4TB; Toshiba 1.5 T, etc. They cannot be deleted and serve no purpose. Each folder has a hidden file called .Trashes and an empty subfolder.
They are not causing any noticeable problem (other than being visible and taking up space in Finder), but I want to delete them.
I cannot add myself to the group and cannot make any changes whatsoever. Disabling SIP does not help. Terminal commands "rm -R" etc. do not work.
