Error generating Xcode project files

Apologies as I am new to Unreal, Git, Xcode, and Mac development, so I need a bit of hand-holding. (I am used to CryEngine, Perforce, Visual Studio, and Windows Development… go figure.)

I carefully followed the instructions to fork and clone the promoted branch of Unreal 4.9 and it seems to be working. Setup.commend reported that it was 100% complete when I ran it in the terminal.

GenerateProjectFiles.command is not working. The error is below. Where I can I obtain the missing UnrealCEFSubProcess.app? Will this fix the error below?

Thanks!

I have the same problem. Have you found a solution?

I have the same on 4.10.
Any solutions?

in your terminal cd in your Unreal Engine directory run the following:

mkdir -p Engine/Binaries/Mac/UnrealCEFSubProcess.app && ./GenerateProjectFiles.command

this should fix the problem and then generate the .xcworkspace file.
