NI software with a hardware dependency, such as MASCHINE, KOMPLETE KONTROL, TRAKTOR, GUITAR RIG and Controller Editor, may not recognize the corresponding hardware devices when an outdated version of the AVID CoreAudio HAL plug-in is installed under OS X 10.10.5 or higher.
1. Update the AVID CoreAudio Driver
In most cases the issue will be fixed after the installation of the latest update of the AVID CoreAudio Driver.
If installing the latest update of the AVID CoreAudio Driver is not an option or the issue persists, please continue:
2. Removing the Avid CoreAudio Plug-in
Disclaimer: This procedure describes the manual uninstallation of a third-party manufacturer component. Native Instruments cannot be held responsible for any damages to your system caused by following these instructions.
- Open Finder and navigate to the folder:
Macintosh HD > Library > Audio > Plug-Ins > HAL
- Copy the "Avid CoreAudio.plugin" to another location, for example the Desktop
- Delete the "Avid CoreAudio.plugin" from the HAL Plug-in folder.
- Type in the admin password when prompted.
- Restart your computer.
While you can fully use Pro Tools without the Avid CoreAudio plug-in, it is not possible to monitor the audio output of any CoreAudio application using your Avid HD audio interface after removing the file. If you should require this functionality again, move the file back to its original location in the HAL folder and restart your computer.
3. Updating / Removing Other Plug-ins
Additionally, these plugin files may cause similar problems when launching a NI application:
- "Digidesign CoreAudio.plugin"
Remove these files from the HAL folder as explained in step 2.
If there are more ".plug-in" files in this folder, visit the manufacturer's website and install the latest updates for these plug-ins.
Should the problem persist, try temporarily removing the ".plugin" files from the HAL folder as explained in step 2.
