Hello!
We've been playing this game with my girlfriend for a little while, she is playing on Mac. At first the game ran relatively smoothly, only a few crashes on specific maps, namely the Plateau and Old Fortress maps. However ever since the summer event started yesterday she has been experiencing constant crashes, on startup, on the start of a battle, mid battle when we were playing a few minutes, and she keeps disconnecting. In short the game became unplayable for her. We've posted on the official forums and created tickets, since this game is officially released by Wargaming on Mac, unfortunately they couldn't help. They've actually directed us here, so I'm making this forum post on her behalf. She is using a mid-2012 Macbook Pro 15" Retina. The specs are: 2,3 GHz Intel Core i7, 8 GB 1600 MHz DDR3 RAM, Nvidia GeForce GT 650M 512 MB, she is running El Capitan. We are running the latest version of the game which is 2.0.6.408160. I'm also posting a few of the backtrace logs here in replies, maybe they will help.
Please advise on what to do, because we had loads of fun with this game while it was running in its previous state.
Thank you in advance!
