I am trying to download Unreal Engine 4.7 Preview 2 with my Mac via Unreal Engine Launcher → Library → Add Engine.
The download goes smoothly for a few minutes, but then the 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 the % CPU is still moving between 50 - 60% range, does that mean the download is still ongoing, despite the launcher is going unresponsive?
Have you been able to use earlier versions of the editor? Can you give us your system specs? You can find the information we need in the Apple Menu > About This Mac. Just copy all of that and paste it in a comment (minus the serial number). Thanks!
I took a look at your logs and what’s happening is you’ve experienced a crash and the Crash Reporter window has frozen when attempting to open up after the crash. Unfortunately at this point in time, Yosemite currently has several known issues with the unreal launcher. Fortunately, most of these issues should be fixed once the next update for the launcher comes out. Let us know though if you’re still having issues with the preview build once the 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.
