We have a school of MacBook Air laptops using 55″ and 65″ ActivPanels that we just installed a month ago. We are using El Capitan 10.11.6 and ActivInspire 2.8.66693. The software crashes several times a day for all the users. I have attached a sample crash log. It is becoming very frustrating, does anybody have any ideas as to what could be causing it to crash on ALL our laptops?
