I can't seem to open my Minecraft because every time I click on it, it says 'To open Minecraft, you will need a Java SE 6 runtime, would you like to install one now?' And when I click Install, it says 'Scanning for software', then after about two seconds another pop up appears saying 'Can't download software because of a network problem'. My WiFi is working perfectly, and no matter how many times I try to restart the WiFi, reconnect, or unplug and plug the router back in, it still won't work. Can someone help me please? I'm on Mac by the way.
