Minimum requirements are:
OBDeleven application works with phones and tablets with Android version 4.1 and later. The system is using online databases so it requires good internet connection for fast and smooth work.
You can get an old tablet or phone with wifi and bluetooth to do the job.
You can also set up Android on a Windows PC if you are into techy stuff.
If you want to use the live data on your central screen it will not work as its only designed to work in Portrait not landscape. You should look at apps like Torque Pro which also work on your central screen.
For my sins I also use a Mac lol. Tried to find an emulator but none of them support bluetooth which sort of sucks.
I could try running windows on my Mac and installing an android emulator on that but thats getting super tech. Just need to through Linux in there somewhere as well lol.
