Random crash in editor window on Mac

Development Programming & Scripting
1

I just upgraded to UE4.5.1 and I am getting the following crash in random fashion. The crash mostly happens when I try to modify editor or project settings, sometime it also happens when modifying blueprints.
So far what I have seen is the crash is unrecoverable and I have to restart the editor every time it happens. I am on Mac OSX 10.9.5, intel core i7 2.6GHz and 16GB RAM.

Any help is appreciated!

I had the same issue while upgrading from 4.5 to 4.5.1 on OS X 10.9.4. Problem still remains after 10.10 upgrade. Crashes occur randomly while using editor (often when dragging vars to graph in BP) on binary version as well as my local compiled one. On Windows or on Linux no pb with the 4.5.1.

Hi Anshul,

In order to help us pinpoint the cause of your crashes, 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.

Also, please provide the following crash logs:

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

Thanks,
