I moved my project alongside the “Engine” folder inside “/Downloads/UE_5.4/” . You are correct that now, GenerateProjectFiles.command now has a “MyCompanyProjectEditor” scheme inside of the xcode workspace. (I’m a windows guy, does project/solution = scheme/workspace for xcode?)
However, even after cleaning I still get the same error.
There is something in your response that raised my eyebrows. "/Downloads/UE_5.4/Engine/Binaries/Mac/UnrealEditor.app" does exist, and i can even run it, however, why on earth when building “MyCompanyProjectEditor” is it trying to copy anything into the vanilla UnrealEditor?
Other than move folders around and generate correctly I haven’t tried anything else. My next step is to debug UnrealBuildTool, unless you note something I’m doing wrong in response to my question about UnrealEditor above.
Best Regards.
