KiCad generating blank PCB when building from schematic
@Arcatus and @user253751 - that was it. I was in Modern Toolset (Fallback), and when I switched to either Legacy or Accelerated, that fixed it.
For those that find this - you'll find those options in pcbnew under the Preferences menu. I'm on a 2015 MacBook Pro 13&quot; running 10.14 in case that matters, too.
Thanks!
