    [EDITOR] Unusually high CPU usage when running UE4 on Mac OS X El CAPITAN

    Hi,

    As you can see in the attached images, I am getting absurdly high cpu usage while navigating around a simple scene in UE4 for a few minutes (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 tired 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?

    I don't think that will help. The percentage is weird, but you'll get bad performance on that anyways because it's using the integrated GPU which just isn't very powerful and can't run most games very well. Probably doesn't help that the screen resolution is higher than 1080p which is more the standard.
