Hi guys, i’m running a MacBook Pro Retina 13 inch late 2013 with 8 gigs of RAM and plenty of HDD space, and whenever I try to install UE 4 v4.5.1, at some point in the installation, it seems to give me a beach ball of death and I can never finish downloading. If you guys have any advice, it would be much appreciated! ---

I’m sorry, sometimes that documentation in a little vague for Macs. Look just below step 10 to see the directions for where to find them on Mac. ---

So i would just add “-HTTP=Curl” onto the end of the name of Unreal-Engine-Launcher-Mac-Shipping? ---

Not in the end of the “name”, but as a parameter to the executable Unreal-Engine-Launcher-Mac-Shipping that is inside the bundle “Unreal Engine.app”. ---
