We need to replace our main (Windows) computer and would like to go Mac for ease of compatibility. At the moment we run ProPresenter through it along with miscellaneous programmes and apps like PowerPoint and Spotify. We would like to be able to add Midi cues to our tracks on Prime and let the lyrics (and lighting) be automated for the services. What would be the best Mac to buy for the purpose and are there any features we must make sure we have?
