I'm trying the AUV3Host sample project in order to better understand how to implement an AU host app.
Third party plugins (effects and instruments) are populated but, once selected, AUAudioUnit is not instantiated and throws the following error:
code signature in (/Library/Audio/Plug-Ins/Components/LABS.component/Contents/MacOS/LABS)
not valid for use in process using Library Validation:
mapped file has no Team ID and is not a platform binary (signed with custom identity or adhoc?))
All of the third party plugins give me the same result.
