After upgrading to Parallels Desktop 10, I'm having problems shutting down my computer. Getting a popup every time, explaining that Desktop caused problems for the machine to be turned off. After I press the button again, it finally shuts off. When starting the machine, it will automatically start up Windows (inside OSX) as if it was the main operating system. I want it to stay in OSX untill I choose to open Windows. I use OSX 10.9.5. By the way, I originally updated to Desktop 10 for having problems to start Parallels after updating OSX to version 10.9.5. Grateful for suggestions!
