I wanted to try out the Unreal Editor on a up-to-date Mac. However, when starting via the launcher I get this:

Hi Sapd33,

Thank you for submitting a bug report, however we require additional information in order to investigate this issue further. Can you please provide the following?

Are you able to open the Launcher, just not an Engine Version? Which Version are you attempting to open? If you have not tried already, try opening version UE4.12 if possible.

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).

The “System Report:” Apple menu >About This Mac > 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.

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

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

Providing this information and appropriate logs will help us track down and isolate the source of the bug as quickly and efficiently as possible.

Thanks for your cooperation,

.

Hi Sapd33e,

Since we have not heard back from you in a while, we are marking this post “resolved” for tracking purposes. However, if you continue to experience crashes when opening the editor through the Launcher, please respond with the requested information and we will continue to investigate.

Thanks,

.
