Video guide to setting up Caesar III to play natively on MacOS, in widescreen, using the open source Julius project.

  • Use natively from applications
  • Full use of the screen
  • Graphical enhancements


  • A Caesar III install
  • The Julius download, available from the project here

Next steps

I’ll return to this topic at some point to talk about the Augustus fork from this project. While Julius primarily focusses on graphical enhancements, keeping gameplay largely unchanged, Augustus brings enhancements to the actual gameplay too.
