Unable to create new project in UE 4.9

I am on OSX 10.11 and XCode 7.0.1. I downloaded the UE4.9 source code. It compiles fine. When I try to create a new C++ project, it crashes with the following text in the message window. I also updated to the most recent Mono version. Any one know what I am missing?

An error occurred while trying to generate project files.

Did you ever get this fixed?

I’m having the same problem also trying to create a C++ project.

Fresh install of OSX 10.11.2, updated from 10.11.1, Xcode 7.1.1 and Unreal Engine 4.10 release

It is annoying because like with you, the StackTrace is empty, making hard to understand what went on…

I had the same problem with OSX 10.11.2, Xcode 7.1.1 and Unreal Engine 4.10 release.

After searching around, it seemed that the problem was creating the project with the Editor started from Xcode: http://mono.1490590.n4.nabble.com/App-crashes-at-mono-jit-exec-when-launched-from-Xcode-td4666666.html

Starting Engine/Binaries/Mac/UE4Editor.app from finder enabled me to create a project like before.

If this worked for you as well, please accept the answer.

I was stuck where none of the C++ Templates would ever compile. I got messages pointing to target.cs missing starting when it tried to run Mono. It asked if I wanted to have XCode compile it. Obviously … Fine. But XCode then failed saying it could not find UE4Editor-[NAME OF PROJECT]t.dylib

Alexandre Pretyman’s solution
,"Starting Engine/Binaries/Mac/UE4Editor.app from finder enabled me to create a project like before.

Fixed the internal issue and now C++ Templates open as they should.

ORIGINAL CRASH FROM EDITOR MESSAGE …BELOW…
…(note it had the same message with 4.14)…
