Hello after installing Parallels Toolbox I have had huge problems with my MacBook. i do believe Parallels Toolbox gave itself permission to start presentation mode, after that all my icons disappeared from my desktop and my laptop won't go to sleep. i have tried to change the settings, take away Parallels Toolbox permissions, close the application, uninstall the application I still can't see my icons and the laptop won't go to sleep.. I think the only thing left to do is to format the computer? what the actual .... parallels? // angry customer
