MacOSX Crash after hitting the "Play" button

Hi,

I just downloaded UE4, and the editor works correctly until I hit “Play”. Then it crashes and exits. I’ve checked if it was the USB device bug by disconnecting all USB devices to no avail.

I’ve also been searching in the forums, but I have not been able to find anything about it. My system is a MacBook Pro (probably below the specs, but the editor works) with Mavericks (10.9.2). It seems to be related to something with audio, but I can’t find anywhere in the forums or in the answerhub anything about it.

I include the logs in this post, here are the first lines of both of them. First, the basic template:

Has anyone had this same problem?

Hi again,

It seems that nobody else has this problem, or at least I couldn’t find any information about it. Is there an official email address where I can ask Epic about this bug?

Thanks again,

Hi,

I just downloaded 4.1 and it crashes exactly the same way. Is it me only or does it happen to anyone else?

Best,

Hey kikesantos,

I apologize for the delay in response, this post got lost and we’re just finding it now. Are you still experiencing this issue after updating to 4.2.1? If so, could you include your system specs? You can find that information by going to About This Mac > More Info. Thanks!

Hi Ben,

I’ve not updated to 4.2.1, as I cancelled my subscription (I couldn’t use the editor at all). I’m going to repurchase the subscription soon (I just got a Windows PC with a beefier GPU) so I may download it just to try and see if it keeps happening. If it does I’ll post the results in here.

Best,
Enrique

Glad to hear you’re going to give it another try with your new system. I suspect your Mac was under spec by enough to not launch properly, as I’ve seen that happen with other Mac users. Let us know how things go with the PC!
