I am hoping to have the parallels app automatically quit once my Windows 10 virtual machine shuts down. This was something that used to happen on my old mac running El Capitan and Parallels 10. Specifically, there was an option under Options -> Startup and Shutdown that asked: On VM Shutdown? with an option to Quit Parallels Desktop. I do not see that option in the same location in Parallels 15, nor in any other locations I have looked.
