Build & Run on Mac (from source code)

Greetings, I am trying to build & run the latest version of Unreal engine from the source code on Mac.
I can somehow build in Xcode but the problem like below occurs when I try [product] - [run].

And if I try to continue from this breakpoint, the program is aborted at last.
Is there anyone who knows why this problem happens? Here is the system information which I am using:

  • iMac
  • Processor: 4GHz Intel Core i7
  • Memory: 8KB 1867MHz DDR3
  • GPU: AMD Radeon R9 M390 2048MB
  • Storage: total 1.02TB, 609.66GB available, Fusion Drive
  • OS: OS X El Capitan (10.11.5)
  • Xcode 7.3.1
  • Apple LLVM version 7.3.0 (clang-703.0.31)
  • Source control: UnrealEngine - release

Please let me know how to solve this problem.

Thank you

Hey thot135-

Can you provide the full output from your compile attempt? Also, since you were able to build the code, could you try opening the editor through the .command file in the Source/Engine/Binaries/Mac folder?


I think I forgot to build “ShaderCompileWorker” before building UE4. It works well now.
I think the installation guide for Mac in the page below should be updated:

Thank you
