I am using multi-screen: I am using the primary screen of my MBP plus two external monitors via displayport
When I start the screen recording, it is the message I see on my screen
I go on to select an area for recording
It is where I get stuck: there is simply no way I can start the recording after the selection. I clicked, tried to access the Quicktime app, tried some key combination. But nothing will get the recording to start.
How can I start a the screen recording for part of the screen?
