As you can see in the attached images, I am getting absurdly high cpu usage while navigating around a simple scene in UE4 version 4.9.2 (up to 160% - not sure how that is possible!), which makes my Macbook freeze after about 20 minutes thanks to the temperatures going up to 100 C and more. This is my first experience with UE, so I have not tried it on previous versions of OS X on my machine. I have read many related forum posts and tried the proposed solutions, such as disabling the realtime rendering of the viewports, but nothing seems to work.
I have used resource intensive applications and games on my Macbook before, but this is the first time that I actually have to restart and wait for it to cool down.
Obviously, this makes UE4 impossible to use for me. I am considering downgrading to Yosemite, but I have no idea if that is going to help. Any thoughts?
