Just when I was setting up Catalina (Beta 19A501i) after an upgrade from Mojave, I mistakenly created a folder at the root on my system drive in Catalina. I populated the folder with some LightRoom libraries, before realising that I should/could not have these at the root of my system drive.
I have copied them elsewhere, but now I need to get rid of that folder, and I can't...
I tried disabling SIP, but still I can't delete the folder (I have enabled SIP again).
What can I do?
