Why won't Unreal Engine 4.15.2 launch on my Mac

It crashes every time I attempt to launch the unreal editor.

I’ve been having the same problem. I was sent an email by one of the support team and they told me to try disabling antivirus, restarting the system or uninstalling UE4 and reinstalling. Non of those worked for me but i guess you could give it a go.

same: tried it all and it still won’t launch

Hey mabdog-

The callstack from your crash matches a known crash that has been resolved for 4.16: Unreal Engine Issues and Bug Tracker (UE-41587) . You can try downloading the 4.16 preview to see if you still encounter this issue there.

Cheers
