Hello, I just downloaded Unreal Engine 4.15.1 and clicked yellow launch button for the first time. Crashes immediately, will not launch.

Running OS X 10.12.4
3.5 GHz Intel Core i7
32 GB 1333 MHz DDR3
EVGA GeForce GTX 560 Ti 2048 MB

Any assistance is greatly appreciated. Please let me know if there is any other info I could provide that would help solve this issue.

Hello ,

I have a couple of questions about your issue to help narrow down the issue you are experiencing.

  1. Have you tried verifying the engine version?
  2. Does this issue happen with other engine versions?

Thanks!
