Can I limit my dock to only show up on the main display? I use 2 external displays with my Macbook. I use the Macbook's display as my main display and only want the dock to ever show up on this display. Is this possible? Right now when I mouse to the bottom of my 2 external displays the dock will pop up there and sometimes push the rest of my windows up. I do not want this.

Thanks!
Your only options are both workarounds:


Uncheck "Displays have separate Spaces" under System Preferences > Mission Control
Pin dock to right or left instead of bottom (obviously not ideal if you're a bottom pinner)
