I have an older model Apple iMac that I am trying to run some software updates on. I am connected to the internet (I am posting this from the computer I am asking about), however when I try to run the updates it tells me there was an error because there is no internet connection. I try to run a network Diagnostic on what the problem could be and it freezes and never goes through. Does anyone know why this could be happening and what I need to do to fix it?
