After hitting a button, something I think related to Touch Bar, which I never had on my Mac, I got stuck with this in the menubar :
I have no idea what this is. And when I click on it, the display goes to sleep. I unchecked Enable Touch Bar support and restarted BTT but it's still there. I really don't know what to do. Does anyone know what this is and how to get rid of it? Thanks in advance for your help.
Edit : Problem solved. I reinstalled an earlier version of BTT and that thing is now gone. But I'm stil wondering what this is. If someone has a clue...
