I just started using OS X El Capitan on a new Mac Book Pro. I was looking forward to using split screen mode but I cannot get it to work. I have read online (cnet and apple) that there are two methods:
- By pressing and holding on the green circle with two outward pointing arrows.
- By making a window full screen, then using mission control to move another application to the same workspace.
Neither of these options work for me.
I did find this post which says that you must have 'Displays have Separate Spaces' enabled (found in System Preferences > Mission Control). Is this really required? I often work with an external monitor and it is more intuitive for me to have this setting off.
