Consistent crash on campaign - Mac

The game crashes when I try to invade the same planet, Parzan. Just as I click to start the battle, it crashes. This is the only time it crashes. I have the OS crash log but I don’t know where a game specific crash log is on Mac. I’ve only seen postings for Windows. Any advice/explanations would be great.


Mac Pro Mid 2010, 2 x 2.66 ghz 6-core Xeon, 32gb ram, )S 10.10.3, ATI Radeon HD 5770

I tried another campaign. Same problem came up but for a different planet. This is getting annoying.
