It used to be possible (before Big Sur I think) to rename and remap the system folders (Pictures, Movies etc). What I am trying to do is move the folders to Dropbox like this:
sudo mv ~/Documents ~/Documents_old
ln -s ~/Dropbox/Pictures ~/Pictures
When I do that I get the following message:
mv: rename /Users/neilthompson/Pictures to /Users/neilthompson/Pictures_old: Operation not permitted
I know that it used to be possible because I have been doing it since 2014 but just moved to a brand new machine and now it doesn't work.
Anyone know of a workaround?
