UE4-Epic Games Launcher has crashed on launch

I just downloaded UE4 and in the process of attempting to launch, the launcher has crashed.

I am using:

  • Macbook Pro (15 inch, early 2011)
  • OSX version 10.10.5
  • 2.2 GHz Intel Core i7 Processor
  • 16 GB of RAM
  • AMD Radeon HD 6750M Graphics Card

So I’d really appreciate any information as to what is going on; I’ve searched through the forums and haven’t quite found anything helpful as yet.

Thanks!
