The editor immediate crash after startup on my Mac?

Hi everyone,

The moment I start up the editor (either a new project or one of the sample projects) it loads up, and a tutorial window pops up, then the infamous colored wheel of death starts spinning and next thing it crashes and asks if I want to send my error report.

I’ve tried the USB patch, but that doesn’t seem to be the problem.

I’m running an iMac 27", OSX 10.9.2, 2.8 ghz intel core i7, 8 gb 1067 mhz ram and an ATI radeon HD 4850.

Any thoughts?

Sorry about that. Your graphics card is below the minimum system requirements of current version of UE4, as it doesn’t support OpenGL 4.1. We are working on adding support for OpenGL 3.3 cards and hopefully it’ll be ready for UE4 4.2 release, but for now there’s no workaround that I know of.
