I'm playing on a macbook and cannot move armies because there is no way to right click. I've tried Shift+Click, Ctrl+Click, Command+Click, and Alt+Click. Is there anyway to rightclick without physically plugging in a mouse?
I had this problem too first time I ran EU4. Solution: go to Preferences -> Trackpad. There is an option under "one finger" called "secondary click" - it allows you to select lower left or lower right corner of the trackpad as your "right click". Note that it doesn't work by tapping, you need to physically click the trackpad in the designated corner to get the right click working.
Now if I could just fix the display problems (all sprites are solid black) and the glacial performance...
