"Incompatible Audio Units found" when launching Logic with Phobos installed on Mac OS 10.13 (High Sierra)




  • Andy Stark

    Tried this, and it did not work. Instead of getting the incompatible audio unit message, the system just says that Phobos failed validation. 

  • Andy Stark

    I have tried deleting it and reinstalled, now I am back to Incompatible Audio Units found" when launching Logic. I am running High Sierra 10.13, Logic 10.3.2. Need help here.

    Andy, I had the same issue as you until I went into the hidden user library folder and found a duplicate in the audio/plug-ins/components folder and deleted it. I copied the new file into the main Library folder and Phobos validated properly finally.

  • Andy Stark

    I have deleted , all, and reinstalled. No luck. The hidden library folder has a duplicate as short-cut in a folder called _MACOSX. I have deleted this too, but it came back in the reinstall. Are you saying that I should delete again? The BT Phobos.component file in audio/plug-ins/components is the correct file.

  • Andy Stark

    I went into the hidden user library folder and found two duplicates, one in the audio/plug-ins/components folder and one in audio/plug-ins/component/_MACOSX and deleted both. I then copied the new file into the main Library folder, restarted the computer, and Phobos validation still failed.

  • Andy Stark

    Ok, just for the record. I put back audio/plug-ins/component/_MACOSX with shortcut link, reloaded core audio, now I am up and running. Based on this, I suspect there is still an issue with the install sequence. Because I deleted all, then did a reinstall, you would think that the installer would know what to do. Guess not. Thanks for your insight. Veery helpful.

    Spoke too soon. Phobos is working, but still shows as incompatible So the fix is not complete.

  • Jason Carey

    What caused me to look around for duplicates was the fact that two instances of Phobos were appearing in Plug-In Manager. When I reset selection and scanned one of them the window was blank. The second version had an error about a version mismatch. I don't see the _MACOSX directory on my system. I will also add that I removed all plugins from my user library, including the VST's. Have you disabled system integrity protection? Mine is enabled, which is the default. I manually deleted the BT Phobos.component out of the main Library components folder and then manually placed the new download into there and after authenticating launched Logic, went into the Plug-In manager and reset and scanned successfully.

  • Andy Stark

    No I have not disabled system integrity protection. Also I did remove all plugins from my user library including VSTs. And tried again without the _MACOSX directory. Still getting an incompatibility error, but Phobos is working. Very maddening.

    Worked perfectly, thanks guys!

    I use Logic 10.4.4 and Digital Performer 10. Phobus works fine in DP but I get no audio out in Logic. I've followed all the fix recommendations and still no audio output in Logic. It scans successfully in the audio units manger and loads as a plug-in with no problems. Just no audio out from Phobus in Logic. ???
