Unreal Editor build hangs forever - MacOs Sequoia

Development Getting Started & Setup

Hi everyone, first of all thank you very much for creating this content.

I am following the Unreal Engine Radme on Github to install it on my Mac.
But I am having the following problem: when I build Unreal Editor, it hangs forever without completing (neither succeeding nor failing).
I managed to complete all the previous steps without any problems.
These are my machine specs:

  • Mac M1 Pro
  • oS: Sequoia 15.0.1
  • Xcode 16.0

Do you have any idea how to solve this problem and build Unreal Editor?
Any suggestions would be helpful, thank you in advance!

The issue applies to all build attempts, not just for the Unreal Editor. I already raised a bug report, but have not received a response from Epic yet.

Also check out this post for a possible workaround.

Thank you for the answer. I thought it’s something related to the new Xcode and Sequoia…

In the end, I managed to build it succesfully after waiting for 2 hours, more or less

I think you’re right that it could be related to either Xcode or Sequoia. Maybe a new security restriction that prevents the Unreal build tool from terminating processes, who knows.
