Screen recording with Quicktime not working while using HDMI output
I'm trying to record the screen on a Macbook Pro Late 2014 with Yosemite. I'm trying to make video of presentations while plugged into a projector via HDMI. When I try to record the screen Quicktime won't allow me..but it will when I unplug it..Any ideas why or fixes?..
MacBook Pro with Retina display, OS X Yosemite (10.10.5), null
