I am running Ubuntu 14.04 fullscreen in Parallels Desktop 12 for Mac on a MacBook Pro running OS X 10.11.6. Whenever I move the mouse to the very top of the screen in Ubuntu, the Mac toolbar appears with the Parallels options. How do I stop this from happening? I have tried the items discussed here without any success: https://forum.parallels.com/threads/how-to-stop-top-bar-popping-up-in-windows.339437/#post-817025 http://kb.parallels.com/en/123101
