I install Parallels 11 on my Mac 10.11.3, and install Ubuntu 12.04 on Parallels. When I working on Ubuntu with full screen, I cannot receive any Mac notification, like Email, iMessage, etc. Actually, when I switch to Mac, I can see the notification, but I cannot hear the sound. That is not convenient, I may miss something important when I working on OS on Parallels. How to fix it?
