Rarely, Mac users may encounter a random error message which appears somewhat disconcerting, with an macOS pop-up message saying “Unapproved caller. SecurityAgent may only be invoked by Apple software."
The simplest way to get rid of this error message is to boot into Safe Mode, then reboot as normal. Amongst other things, this flushes out many system level caches, which will resolve the Unapproved Caller message.
To Boot in Safe Mode:
- If the Mac is powered on, properly power off the machine.
- Wait a few seconds, then press and hold the “Shift” key while powering on the Mac.
- Release the “Shift” key as soon as the Apple logo display on the boot screen.
Performing these steps will cause the Mac to boot in Safe Mode. To verify the system properly booted in Safe Mode open the System Information App.
- The System Information App can be found by press the Command (⌘) + Spacebar keys simultaneously, which will open the Spotlight search bar.
- In the Spotlight search bar type in “System Information”, the System Information App will be listed as a top hit.
- Open up the System Information App and scroll down until you see the “Software” header. Click on the “Software” header, which will display the System Software Overview.
- Look for the field labeled “Boot Mode”. If the field is populated with the word “Safe” then the computer successfully booted in Safe Mode.
To Exit Safe Mode:
- Navigate to the Apple () Symbol located in the upper left hand corner of the screen.
- Click on the Apple Symbol scroll down and click the “Shutdown” OR "Restart" option.
The computer will by default boot normally the next time the machine is powered on.
