I am trying to download Unreal Engine 4.7 Preview 2 with my Mac via Unreal Engine Launcher → Library → Add Engine.
download goes smoothly for a few minutes, but then whole unreal launcher application is going unresponsive:
I am using MacBook Pro with OS X Yosemite 10.10.1, and I can see in Activity Monitor % CPU is still moving between 50 - 60% range, does that mean download is still ongoing, despite launcher is going unresponsive?
Have you been able to use earlier versions of editor? Can you give us your system specs? You can find information we need in Apple Menu > About This Mac. Just copy all of that and paste it in a comment (minus serial number). Thanks!
I took a look at your logs and what’s happening is you’ve experienced a crash and Crash Reporter window has frozen when attempting to open up after crash. Unfortunately at this point in time, Yosemite currently has several known issues with unreal launcher. Fortunately, most of these issues should be fixed once next update for launcher comes out. Let us know though if you’re still having issues with preview build once launcher update goes live.
I have done some googling myself and I guess it’s related to Wi-Fi disconnection issue of Yosemite (which has not been fixed in version 10.10.1). Hope that Apple’s upcoming upgrade will truly address this problem.
