Hi, my Macbook Pro has been crashing and lagging since the latest update. I’ve tried all of the blizzard guidelines which could help to improve the performance but they didn’t.
I even tried to play in windows mode but that didn’t help either 
all graphics settings are set to lowest, resolution lowest but still, mostly, when I enter dungeons i can expect a crash at any point and have to restart my mac. Even in open world where there are more players and we are attacking some mobs or just casually playing (farming etc) - mac crashes or a hard lag for few seconds follows.
Now the game is completely unplayable 
I didn’t have those problems on patch 8.2 and 8.2.5. The game ran smoothly without problems.
Specs
13inch Macbook Pro early 2015
macOS Catalina
version 10.15.2
processor 2,9GHz Dual-core Intel core i5
memory 8gb DDR3
Graphics Intel Iris Graphics 6100
Please help!
Thanks
