Your comments

Thanks for the fast reply. First of all: Wish you all a nice christmas time and a happy new years eve in advance.

I will wait for a comment on that next year :)

For the performance: The IntelHD 515 runs well on minimum settings were as the 550 runs the game even on medium settings without framedrops (but the game breaks on campaign 7). Everything works fine, expect the campaign. I got some more details on that as you requested:

The crash happens when campaign 7 is fully loaded and starts (transition from loading screen to game). You can hear the sound of gold dropping as a level starts, still in loading screen at 100%. Then the crash happens immediately.

specs:
MacBook Pro 13" Late 2016
