Hi Sudorossy, How far do you get before crash occurs? Are you trying to open from Launcher or have you compiled from source using GitHub? Are you able to get to Project Browser to create a new project, or does it crash before then? Please copy/paste information from Apple Menu \> About This Mac (minus Serial Number). Thanks! ---

Hi , thanks for reply. I open from launcher, on clicking “Launch” either from main screen or from “Library”, launcher minimizes and a second later crash log comes up. I can’t create any projects. Info from “About this Mac” OSX Yosemite Version 10.10.2 (Retina, 13-inch, Late 2013) Processor 2.4 GHz Intel Core i5 Memory 4 GB 1600 MHz DDR3 Graphics Intel Iris 1536 MB Currently my Display options are on “more space”, but I get same error if I leave display options on default. ---

Here’s attached crash reports. There were a few folders in that folder (I assume from multiple times I’ve started program), so I zipped them all. ---

10.10.2 is a pre-release build, nothing has been tested against it, but even then that’s an odd error to be seeing. It suggests that OpenGL can’t create context, but I can’t reproduce that here on my machines. As a first step if you can try running 10.10.1 (current public build of Yosemite) just in case it is a 10.10.2 issue. ---

Thank you! I had no idea it’d kept updating to beta versions after Yosemite released. This solved my launch issue. Thanks again. ---

Installed completed … When I clicked launch on Epic Game Launder, it crashes right away. I need help with this. Thank you.
