Unapproved caller SecurityAgent error message in Mac OS X

Rarely, Mac users may encounter a random error message which appears somewhat disconcerting, with an OS X pop-up message saying “Unapproved caller. SecurityAgent may only be invoked by Apple software.”

This message can appear at random when using certain apps, or after logging in or a reboot, and is sometimes followed by crashing and other bad behavior. Because the message is vague and mentions SecurityAgent and an ‘unapproved caller’ many users perceive this to be some sort of eavesdropping or attack event, but the good news is that is not the case, and you can fix the error message quite quickly and you will likely never see it again.

Apr 25, 2015 - 8 Comments

Indeed, you can use Facebook Messenger to message friends from OS X, and in moments you can set up the Mac Messages app to function as a Facebook Messenger client in OS X.

Using Facebook Messenger from the Mac is really quite simple, but it’s entirely separate from configuring Facebook sharing from the Mac, so if you have done one but not the other, you’d need to complete both to have the full Facebook functions of sharing, posting, and messaging available to you in OS X.
