From disconnections, transmission of the audio but not the video, a signal that does not appear when an external monitor is connected… Although not all failures attend to a similar situation or conditions that allow isolating the failure in a more precise way. The only thing that has been identified is an error with an extension called APExtframebuffer .

Deleting this extension, and in its absence the AirParrot driver in those who have used the app, seems to be solved. To do this, as described by a user, just navigate to the relevant locations SystemLibraryExtensions and LibraryExtensions and remove both APExtframebuffer.kext and AirParrotDriver.kext . Then reboot and you’re done.
