Hey mate,
I'm no good with logos but there is a way to play the demo with a mac and is completely legal. I use a mac and by using bootcamp assistant (an app pre-installed on mac in your utilities folder). I partitioned my disk to download windows 10 onto my Macbook Air. All you need is 50gb of free space on your mac, a 5gb+ flash drive and the windows Iso file for mac (easily downloadable off the microsoft store for free). I initially thought you only get windows 10 for free for a 1 month free trial but I have been using it for over 2 months. I recently learnt you get office for a 1 month free trial and windows 10 operating system indefinitely.
Here is an instructional video to how it is done:

This is what a partitioned disk looks like. If you no longer want to use windows 10 and it is taking up space, you can easily unpartition the disk as many times as you want and return your device to full capacity with an only mac operating system.
The whole process of installing windows via bootcamp and then installing DBC 17 is about 3-4 hours. (2-3 hours for windows 10, 1-2 hours for DBC 17)
