[4.7 Preview 1] Crash on startup on OSX

Running: Yosemite 10.10.2 (4.6.1 release runs fine)
Callstack:link text

Hi TommyBear,

I was not able to reproduce the issue on our Mac. In order to pinpoint what is causing your crash, in addition to the callstack you have already sent, please provide more information about your Mac’s specs.
You can find this in the Apple menu >About This Mac>More Info> Add the information from this window (serial # not necessary).

We also need the following information from the “System Report:” Apple menu >About This Mac>More Info> System Report>Hardware (All information listed in the “Hardware Overview.”) You can cut and paste this information or provide screen shots, whichever is more convenient.

**Did you hit “Submit” on the Crash Reporter pop-up to send the Crash Report to Epic?

We also need the following logs:

The UE4.log (Located: ~/Library/Logs/Unreal Engine/Editor/)
The ProjectName.log (Located: ~/Library/Logs/Unreal Engine/ProjectNameEditor/)


Hi TommyBear,

Using the information you’ve provided, I’ve submitted the following bug report: JIRA [7248] If the developers are able to identify and resolve this issue, an update will be added to this post.

Thanks for your help identifying this issue.
