Building Mac target

I initially created my project on my Windows machine, where everything works fine. Checked my code into version control, and decided to do some work on my Macbook. I generated the project files with the supplied bash script.

I can build the Mac target within XCode without any issues, but when I attempt to run it I get a failed to launch error “SBTarget is invalid”.

I’ve tried different architectures, and tried building both DebugGame and Development, and I seem to get the same result either way. I can however build AND run the editor target, which loads all my assets and everything into the UE4 editor.

Any ideas?

Realized it might be worth mentioning I did not build the engine from source, I created the project with the launcher provided editor. And when I generated the project files on my mac I simply did:

cd /Users/Shared/UnrealEngine/4.0/Engine/Build/BatchFiles/Mac
./RocketGenerateProjectFiles.sh /SomePath/project.uproject
