It should have been installed in the `/Applications/UnrealEngine/Engine/Binaries/ThirdParty/Mono/Mac/lib/mono/2.0/mscorlib.dll' directory. The assembly mscorlib.dll was not found or could not be loaded. When building the GitHub Release - like told in the description - using the mand file I got the following error: (Mono was installed using the seperate installer) Setting up Unreal Engine 4 project files.
Dear Community, I am unable to build the UE4 Editor on my Mac.
