Am I supposed to have both a Library/Privileged Helper Tools & a Library/PrivilegedHelperTools folder? Library/Privileged Helper Tools is empty. Library/PrivilegedHelperTools has 3 items belonging to known installed applications within it.
No, you should only have “PrivilegedHelperTools” without the spaces. Make sure the folder with spaces really is empty including hidden files, then it should be safe to delete.
