Ditto. I am in the middle of testing this game on three separate mac os x machines and they all have varying levels of poor performance. What are the hardware/software specifications for your 2017 machine?
right now I'm testing it on the oldest machine : MacBook pro 2011 w/ 2.8 GHz i7, 8GB RAM, Intel HD Graphics 3000 and a samsung evo ssd. software version is 10.12.6 (low Sierra)
It was crashing at the initial new game screen - more than just the first time - but I reduced the frame refresh rate to 60 and disabled the auto frame rate detection feature. it can now get to the first character creation page.... and 5 minutes after clicking, page 2! not recommended
