Editor response on OSX

Hi,

I’m using UE4 on a MacBook Pro with i7 and 16Gb RAM running macOS Sierra 10.12.5

I am having some frustration with the UI.

I open things like preferences and can’t select values to change and sometime can’t even move the window around.

Are there any settings that I can tweak to get it to work?

EDIT:
It works most of the time but the times it doesn’t are really quite annoying. I also sometimes have to select components multiple times to get the details pane to update with the actual settings for the newly selected component
