Hi, I installed Catalina but it seems to have caused my system drive to become 'Read Only'. I am admin and yet if i look at the disk's info pop up and try to change the admin to Read and Write (after clicking the padlock), it only changes to Read and Write for a second then reverts back to 'Read Only' and I get an error pop up that says 'The operation can't be completed because you don't have the necessary permissions'. I can't drag anything onto the root drive or do anything with it really, I only have access to the user and public folders. Catalina functions OK but I have this annoying restriction, being the admin and being denied access to my main drive, the format is APFS - If you have any Ideas I would appreciate it - thanks

Take a look at this thread:

Post 130 has a link to a Bombich Software (CCC) page that has a nice overview of the OS disk structure changes.

OK thanks that's frustrating, it moved things like my Dropbox folder into a special folder and I had to resync everything and make lots of changes to aliases because they were no longer in their original locations and I couldn't put them back because the drive is now read only . . . .
