Unapproved Caller
I am recently updated OS X Mavericks and i was using just fine for about 2 weeks, recently i started to see issues and my loginwindow keep on crashing, When i try to open App Store it throws error " Unapproved Caller SecurityAgent may only be invoked by Apple Software" , it throws same error when i try to logout or restart my MBP.
Let me know if anyone has resolution to this problem.
MacBook Pro, OS X Mavericks (10.9)
