The issue on Mac is due to the fact that I can't afford the price of purchasing the official Apple Developper Account, so it won't recognize the program as trustworthy. As a result, the program fails when it tries to access the files it needs on the disk.
You have to manually give permissions to the program. I remember people that figured out how to do it, but I can't remember since I don't have a mac and have never done it myself.
