    What if that didn’t work.
    After the safe mode the unapproved caller messages will come again.

      Hello, Kasper! Removing the contents of this folder does not affect the system as they are only cached files. This will only need to be done once, then a RESTART of the system and the Unapproved Caller error will go away. If you still are having issues, I recommend to visit Apple Store, all Software Warranty is paid for so they don’t charge anything.
