Hello. we have an issue with FMOD (2.02.13 version) on an Unreal project with MacOS build. Th paths are incorrect after packaging the build to TestFlight, maybe you can help us with this question.
We’ve tried several things which usually resolve such issues - for example we’ve tried the following command:
install\_name\_tool -add\_rpath @executable\_path/../Unreal/YourGame/Plugins/FMODStudio/Libs/Mac /Path/To/YourGame.app/Contents/MacOS/YourGame
The problem is that after packaging, we have the following paths for the FMOD library (please refer to the attached file). We have removed, added, and changed the rpath entries, but the build from TF still cannot load the library.
In our experience usually this command " install\_name\_tool-add\_rpath " is sufficient to fix such stuff, however it doesn’t help somehow this time
This is an example of rpaths when we assemble the build (and it works) without packing it for TF:
## otool -l /Users/developerplayjoy/Documents/BuildsMac/ShipBuild/Mac/Sycamore-Mac-Shipping.app/Contents/MacOS/Sycamore-Mac-Shipping | grep -A2 LC\_RPATH cmd LC\_RPATH cmdsize 32 path @loader\_path/ (offset 12)
```
cmd LC_RPATH
cmdsize 32
path @executable_path/ (offset 12)
```
## – cmd LC\_RPATH cmdsize 40 path @executable\_path/../../../ (offset 12)
```
cmd LC_RPATH
cmdsize 104
path @loader_path/../../../../../../../FortSolisMacosEngine/Engine/Plugins/FMODStudio/Libs/Mac (offset 12)
```
## – cmd LC\_RPATH cmdsize 72 path @loader\_path/../UE/Engine/Plugins/FMODStudio/Libs/Mac (offset 12)
```
cmd LC_RPATH
cmdsize 80
path @loader_path/../../../../../../Engine/Plugins/FMODStudio/Libs/Mac (offset 12)
```
## – cmd LC\_RPATH cmdsize 112 path @loader\_path/../../../../../../../FortSolisMacosEngine/Engine/Binaries/ThirdParty/Intel/TBB/Mac (offset 12)
```
cmd LC_RPATH
cmdsize 72
path @loader_path/../UE/Engine/Binaries/ThirdParty/Intel/TBB/Mac (offset 12)
```
## – cmd LC\_RPATH cmdsize 88 path @loader\_path/../../../../../../Engine/Binaries/ThirdParty/Intel/TBB/Mac (offset 12)
```
cmd LC_RPATH
cmdsize 104
path @loader_path/../../../../../../../FortSolisMacosEngine/Engine/Binaries/ThirdParty/Ogg/Mac (offset 12)
```
## – cmd LC\_RPATH cmdsize 72 path @loader\_path/../UE/Engine/Binaries/ThirdParty/Ogg/Mac (offset 12)
```
cmd LC_RPATH
cmdsize 80
path @loader_path/../../../../../../Engine/Binaries/ThirdParty/Ogg/Mac (offset 12)
```
## – cmd LC\_RPATH cmdsize 112 path @loader\_path/../../../../../../../FortSolisMacosEngine/Engine/Binaries/ThirdParty/Vorbis/Mac (offset 12)
```
cmd LC_RPATH
cmdsize 72
path @loader_path/../UE/Engine/Binaries/ThirdParty/Vorbis/Mac (offset 12)
```

cmd LC\_RPATH

Also as far as we know, this issue was already fixed in older versions of FMOD and this shouldn’t have been an issue in the first place

This is an urgent issue for us, so we’d appreciate help on this

What Unreal version are you using? I can’t see the attached file you mention that contains the broken paths - can you copy/paste it maybe?

We’re using UE version 5.2 (tried with 5.2.1 too). Can’t attach the file due to your site’s restrictions. Here’s the info from the log: [Translated Report (Full Report Below)------------------------------------- - Pastebin.com](https://pastebin.com/ptjjkwfF)

Thanks for the info. According to your log it looks like libfmod.dylib is being found (so your rpath setup is working fine) but it’s failing to load due to an invalid code signature :
> ‘/Applications/Sycamore-Mac-Shipping.app/Contents/MacOS/…/UE/Engine/Plugins/FMODStudio/Libs/Mac/libfmod.dylib’ (code signature invalid in \<6BCD797A-A71A-3AA9-8FC6-8B4253BB388C\>
Try running the codesign command to see what’s going on with the signature on libfmod.dylib :
`codesign -dvvvv libfmod.dylib`

Hey Andrew,
We’ve tried this and are getting the same issue

Thanks for the detailed information. The “codesign -dvvvv libfmod.dylib” command just displays information about the codesign status of libfmod.dylib. According to the output you posted, I can see that Testflight has codesigned the libfmod.dylib :
> Authority=TestFlight Beta Distribution
> Authority=Apple Worldwide Developer Relations Certification Authority
> Authority=Apple Root CA
This is to be expected - everything in your packaged game should be signed as part of your packaging process - but I don’t know why the signature is appearing to be invalid when your app comes out of Testflight. The fact that your game works when you don’t package it for Testflight seems to confirm that the FMOD dylib is being found ok, so it doesn’t look like an rpath problem - everything works fine until you push it through Testflight.
I suspect it may be something to do with your codesigning setup. Unfortunately, these problems get more frequent and more finicky with each new macOS release. A good source of information on troubleshooting these sort of problems is this :

And here’s an Unreal-specific article that may help :

Let me know if any of this helps.

Hey @alexvvv1 ,
Were you able to resolve this? I am facing the same issue related to libtbb.dylib.
I have signed everything correctly, and the app is running in my machine however when i send it to app store and download it from testflight, it is throwing error (code signature invalid in \<6C6BD7A4-4818-33BF-827E-22FE4ED15686\> ‘…/UE/Engine/Binaries/ThirdParty/Intel/TBB/Mac/libtbb.dylib’ (errno=1) sliceOffset=0x00004000, codeBlobOffset=0x0003D250, codeBlobSize=0x000056B0)
