You can use OMS on a Mac on screen (without VR equipment) provided you are running a Mac device running iOS Mojave or Catalina.
Please note, Apple computers are not set up to be compatible with Virtual Reality equipment. You will need a Windows machine with a powerful graphics card in order to realise the full benefits of VR simulation.
