UE4 Stuck at 10% or 18% on startup (Mac OS X 10.11)


I just downloaded UE 4.8.3 and when I launch it, I get a blank window with written “Initializing 10%” sometimes it goes up to 18% but doesn’t change… When I try to click on it or do something, the app doesn’t respond.


It may have to do with the fact that I’m using OS X 10.11 El Capitan Developer Beta 3, but I want to be sure.

Thank you!

EDIT: btw, I’m on a MacBook Air last generation. (Intel HD 5000)

Ok, fixed in Dev Beta 4!
