Hi everyone,
I encountered an error while trying to package a macOS build with Unreal Engine 5.6 on my Mac:
Unknown DefaultArchitecture value found ('arm64+x86_64') in .ini
AutomationTool exiting with ExitCode=1 (Error_Unknown)
RunUAT ERROR: AutomationTool was unable to run successfully. Exited with code: 1
I tried fixing it in DefaultEngine.ini by changing the DefaultArchitecture value. I tested: “arm64+x86_64”, “x86_64”, “arm64”, “MacTargetArchitectureUniversal”, and “MacTargetArchitectureHost”, but none of them worked. I also tried changing it via command line, but that didn’t help either.
Does anyone know how to fix this?
