can’t move or copy a file or folder to my Macintosh HD
I just upgraded my MacBook Pro to the latest version of Catalina. Previous to this upgrade I had several folders on the Macintsoh HD (same level as System, Applications...). But after this upgrade, can not move my folders back (or create a new folder) to this location. Admin is only Read Only (just like my iMac) which is still on Mojave and I can move and create folders at this level. Using the Admin account, I can not change the permissions for admin to Read & Write. What happened/changed? How can I change this back to allow folders to be created there at this level? thanks
