FMOD works great in the editor, but packaged builds crash immediately, unable to find the libfmodL.dylib file. The file definitely exists, and it seems to have the correct paths set up, using @rpath. Not sure what to do here exactly, any tips? I’m on MacOS 10.14, XCode 9.4.1, FMOD 1.10.12.

Sorry for the delay, it appears that this is an unwanted and unexpected side effect of some changes made to the Unreal Engine. They are looking for a fix for this but in the meantime modifications will need to be done in the engine: https://udn.unrealengine.com/questions/500361/built-mac-game-unabl…

The solution requires access to the UE4 Source Engine, as you need to modify some engine code and then also recompile it (the Unreal Build Tool at least).

Thanks Cameron. Do you have an ETA for the fix on the side of Unreal?

Not at this point, they said they would let us know as soon as they figure out a proper fix.

Okay, so I made a big mistake as I worked on the 4.22 version before knowing there was a packaging bug with Fmod.

Hey Tom! I’d be happy to help. Once the FMOD issue is sorted out, you’ll also encounter a great number of other issues packaging for mac desktop. I’ve created a script that fixes all the issues with a packaged build, and I’ll put that up on github later tonight. In the meantime, the exact command fo…

Thank you so much @jeremyabel this is very kind from you! I’ll wait for the script as I need to send a test version to my team mate. Do I need to use/run the UE4 source Engine or does your solution work with the binaries?

It just works with the packaged game binaries. Here’s the script and all other required files, as well as some info in a README: https://github.com/jeremyabel/UnrealBuildMac

Any words on an official fix? I have just tried making a MacOS build on 4.24 and I encontered this issue immediatly.

I have updated the question and currently awaiting a reply from Epic.
