Hi, I’m getting the “fmodDLL not found” error on my osx builds. When I dig into the contents of the .app file I do see fmod and resonance audio in the plugsin though. This only happening on osx builds that were build on PC. My PC builds are fine, my OSX builds that are built on OSX are fine. Any ideas? I’m using Unity 2020.2.6 and the latest version of fmod.

Might be related to line-ending differences between Windows and macOS. Does this thread help at all?

> Sorry for my slow response. It seems that everything suddenly started working again…? This whole thing has been very weird but yeah, I guess it works. I will schedule some builds today to see if that is the thing that causes the process to execute weirdly, I’ll come back later with an anwser.
