Could Norton Internet Security be blocking access to a projector when connected?
On two recent occasions I've connected my 2016 MacBook Pro, running MacOS Mojave, to a projector in a conference room.
My MacBook has detected it is connected to a HDMI cable and something on the other end, but the projector is not displaying my screen. Tech staff have not been able to work out why. The conference room was not my facility and I do not know the projector type.
I have a personal projector that connects every time.
My question is, could my connection settings in Norton Internet Security be responsible for NOT letting the projector connect to my MacBook Pro?
