Hello, I recently downloaded Unreal and can’t even open it, It just crashes everytime I try to start a project. Im using a 27" iMac 2019, with Radeon Pro Vega 48 8 GB graphics.

I will post the crash data below…

What way did you download UE4

If it was from epic games website it should be fine

** create a project, if crash on loading it then find project in files and should find launch the game at the bottom right click that and click generate visual studio project files then above the launch game icon there should be visual studio icon then in v studio run debug game and it should work **
