I've been having issues with my desktop, but not my laptop (despite my laptop not being nearly as powerful). It doesn't matter which map I am in or what graphic settings I have my game set at, I constantly will crash and have horrible loading time. The desktop is running OS Sierra 10.12.6 and is a mac mini from late 2014. It has a 2.6 GHz Intel Core i5 processor with 8 GB of memory and Intel Iris 1536 MB graphics card. Most times the game completely crashes with no error message and won't close completely (the application is shown as running but is completely gone and I have to manually kill it with the Activity Monitor). The game crashes in core areas as well as expansion areas with varying numbers of people. Other than that however, fps is smooth though, which is great! The game doesn't run as well on my laptop though (cries.... 10 fps at lowest settings) so I would love for this issue to be addressed.
