The problem is that Apple has decided not to support my device past MacOS 10.13 which leaves me in the position of having to purchase a new laptop within the next year (assuming that Omnigroup will only support MacOS 10.13 for another year- I don’t know that for sure). I don’t have anything against Apple hardware- it’s high quality and, in fact my 2011 MacBook Air is running great. However, it’s my understanding that MacOS can only be run in a VM on Apple hardware. Thank you- I agree that this would be the better scenario for me, all things being equal. A bit harder to set up, but seems more the right way around. If OF is the only tool that’s missing from his linux experience, maybe it makes more sense the other way around – run your favourite linux and virtualise macOS running OF. In any case, VMWare Fusion or Parallels can run Linux in a VM environment.
