Security Impact of Remove All Sandbox Permissions?
@shak cookie needs permission from macOS to access any files on your computer. So resetting this will cause Cookie to ask again, before it can do anything… ie removing or reading any cookies on your computer.
It’s quite safe to remove the permissions. all that will happen, is all your browsers will be disabled . You won’t lose any of the favourites or settings, you will just need to give cookie permission and re-enable your browsers.
