Mac OS: Unapproved Caller Error

Dean P. Simmer -

Sometimes macOS will generate an "Unapproved Caller" message when attempting to update software. The solution to this is to force-clear the cache on the account. Here's what you need to do.

  1. Reboot the Mac and immediately hold down the SHIFT key, continue holding shift until the loading bar appears

  2. Let the Mac boot into Safe Mode, which will automatically dump caches

  3. When completed, go to the  Apple menu and choose “Restart” to reboot the Mac as normal.

  4. Attempt to update the software that was generating the "Unapproved Caller" error.
