I have a Mac Pro Late 2013 desktop running OS X 10.9.5. My screen recently started showing the graphic below at boot up in the lower right corner of the screen. It is there for a moment, then it disappears and the mac continues booting.
Does anyone know what this indicates or if there is some action I should take? Thanks in advance for any ideas on this.
