Think that should work in Sierra too, but don't have a Sierra machine at hand. It doesn't work in High Sierra or Mojave!

Alternatively, you can turn off app nap completely in Terminal:

defaults write NSGlobalDomain NSAppSleepDisabled -bool YES
Checkbox is not available. System-wide disable of app nap is not possible for me, otherwise my battery is draining.
I found a perl script on the internet to turn off app nap for a specific app using terminal.
