Hello There!

I am trying to build the Handheld AR Template in 4.19 for an iPad from a Win 10 Workstation. (Blueprint Version, Binary Engine, not source compiled). It was insisting on remote building so I set up a mac mini to the remote build machine and it seemed to work.

No issues connecting, nothing wrong with provisioning. It says *Build succeeded and finishes creating the .app directory on the Mac.

Then it starts zipping … until this happens

Finished creating .app directory on Mac (took 19.35 s)

Any help in resolving this is greatly appreciated!

Also, seeing that the build has finished successfully and the .app folder created, is there any other way to finish the packaging process?

Thanks for reading!

I am having exactly the same issue using Unreal Engine 4.20 built from source. I will let you know if I find a solution.

You can’t use zsh as the default shell on your build machine, switch it to bash and it will work right away. I just spent like a day trying to figure this out :confused: At least I found a solution eventually.
