How to make xcode project from ue4 build on windows

How to do this manually???

I am not able to run the ue4 program on mac osx, only on Windows.

I assume, you have Unreal Engine installed on your Mac. If not you need to install that.

Can you not open the .uproject file with UE4, then go to File → Create xcode project ?

Maybe you need to further explain what the problem is, that you are having.
