ERROR ITMS-90511: CFBundleIdentifier Collision on FMOD bundles

[bfskyle]

I am getting the following errors uploading my game to the mac app store:

ERROR ITMS-90511: “CFBundleIdentifier Collision. The Info.plist CFBundleIdentifier value ‘com.fmod.fmodstudio’ of ‘GAMENAME.app/Contents/PlugIns/fmodstudio.bundle’ is already in use by another application.”
ERROR ITMS-90511: “CFBundleIdentifier Collision. The Info.plist CFBundleIdentifier value ‘com.fmod.fmodstudioL’ of ‘GAMENAME.app/Contents/PlugIns/fmodstudioL.bundle’ is already in use by another application.”

I ran into this before, and the fix was to renaming the CFBundleIdentifier in the info.plist file within these plugin bundles. This worked on a previous submission. Now attempting to do an update, if I dont rename the CFBundleIdentifier, I get rejected by the app store, but the build works fine. If I DO rename the CFBundleIdentifier, the game fails to load fmostudioL and no audio works in the game.

We are using FMOD 2.00.13 and Unity 2019.4.9f1

@mathew I think you might be able to shed some light here - saw a similar issue in another thread:

MacOS DllNotFoundException: fmodstudioL

Thank you so much for providing your .app, I was able to reproduce the issue here on my Mac. So the problem is actually due to a codesign validity check triggered because the FMOD bundle has been tampered with. The tampering is the line endings for the Info.plist file contained within fmodstudio.bundle and fmodstudioL.bundle. I was able to quickly fix it here by installing dos2unix via homebrew and running it on the file. We ship the Info.plist files with Unix style line endings as is the norm …

Here you mention that the dll was not found because the info.plist file was tampered with. In my case, it is intentionally being ‘tampered’ with because MacOS App Store requires a unique CFBundleIdentifier, so I am editing it to be unique. Any ideas on how I should be approaching this?

Yep, if you’re modifying the Info.plist that’ll break the bundle for sure, due to codesigning. Sounds like you need to modify the Info.plist and then codesign it yourself.

Thanks for the reply - we are modifying the info.plist, and then codesigning it also, but the issue still persists. My method of codesigning hasn’t changed from previously when it did work, and I have tried a few different methods / parameters for codesigning, none of which seemed to work. Do you have any tips on how I should do the codesigning to get it done correctly?

I’ve successfully followed this process to sign/notarize a Unity game (for distribution outside of the App Store) :
