I installed the public beta 4 and indeed Unreal quits properly now.
You guys need the M3 Max. Only have to force quit once every 3 instances.
The issue has been fixed in macOS 15.1: background cooking processes complete successfully and the building proceeds as usual. Also, force-quit is no longer needed since the editor quits properly now.
Updating to macOS 15.1 does not work for me. Still need to force-quit UE5.4. The packaging still freezes.
Apple M1 Max
UE5.4.5 from source
Edit: UE5.4.4
Can you please share the command line for packaging?
I still have issue with the packaging freeze under MacOS 15.1. Would like to try this but do not know where to start even after going through UE documentation.
I was running into this issue and cherry picking this commit from Epic resolved it for me: https://github.com/EpicGames/UnrealEngine/commit/0c1b3bdc0993c23ae0de2effe9cbf78fea7e8107
Looks like that fix was included in Unreal 5.5.
