I just bought the game on my 2015 Mac Book Pro. Whenever I try and start anything (Campaign or Prologue) it crashes. I found this (https://forums.totalwar.com/discussion/160391/solution-for-the-macbook-pro-2015-13/p1)
and tried it with no success. I might not have been able to locate the correct file, but I think I did. My computer has a 2.7 GHz Intel Core i5 processor, plenty of memory space and a Intel Iris Graphics 6100 card. I've attached the error report. Any help would be greatly appreciated.
