It runs perfectly on a Mac with 10.14.6 installed. settings were on max and it ran about the same speed as I've seen it in videos on Windows. I didn't play for long as this is the first time this game ran on my machine and so I had to learn the simplest things like how to equip stuff but I created a character and spent some time trying to pick up the torch :)
Gives me hopes for Sui Generis :)
