• Купить на gog.com комплект DOOM + DOOM II за $3.99.
• Получить оттуда файлы setup_the_ultimate_doom_1.9_(28044).exe и setup_final_doom_1.9_(28044).exe.
• Установить распаковщик, к примеру на маке "brew install innoextract".
• Распаковать эти файлы с помощью innoextract и извлечь оттуда:

  The Ultimate DOOM/DOOM.WAD
  Final DOOM/Plutonia/PLUTONIA.WAD
  Final DOOM/TNT/TNT.WAD
  

• Положить DOOM.WAD и прочие в ~/Library/Application Support/uzdoom/, и при запуске игры выбирать нужный из них.
