I have a cloud drive folder where I store my documents, pictures, etc. I want to change the documents, pictures, etc in home to point to my cloud drive folder. I was able to rename the Documents folder just using sudo mv and then create a symbolic link for the cloud drive Documents folder, but for some reason I cannot mv/rename the Pictures folder. I always get "Operation not permitted".
I already moved the photo library bundle out to another location and set that as the system photos library in the Photos app.
