How to hide FaceTime audio macOS High Sierra Version 10.13

Is it possible to hide FaceTime audio?

It certainly was possible to hide or move the window in earlier macOS versions but with macOS High Sierra I can't select the window nor can I hide it with shortcuts.

The old version:

The position in the top left corner is very annoying and sometimes I have to resize windows to click on something (for example Safari buttons).

This seems like a bug.

Also other people had this kind of question too: Apple discussion

I have found three temporary workarounds (the last one is the best). All of them force quit the process FaceTimeNotificationCenterService:

• Open Activity Monitor and search for FaceTime. Then select FaceTimeNotificationCenterService, press the red circled button and choose Force Quit.

  

• Open Terminal and type killall -kill FaceTimeNotificationCenterService then press return (⮐)

  With this command you essentially Force Quit the process. (For more information type man killall; -kill sends the signal kill instead of the default signal term to the process)

• For a more permanent solution you start Automator make a new Application. Here you go to Utilities and drag Run Shell Script to your workflow. Write killall -kill FaceTimeNotificationCenterService in the text field and you can save the document.

  

  As a shortcut you can place this Application in your dock so it needs only single click to activate.

Here, I created a small app that you can run after you have your facetime call going that will hide the window. http://onetoshare.com/AH2Bjq
