Control your Denon or Marantz receiver from the Keyboard, the Menu Bar or the Touch Bar.

Enter the device IP or network name into the text field and confirm using the return key. If you have a newer AVR, you might have to include the port 8080 like in this example: 192.168.1.30:8080.

It sits in the Control Strip.

You can download the latest version here. After downloading and unpacking the Denon-Volume.zip, move the app to the Applications folder. If you get a GateKeeper warning on first launch, right-click the app, select open and confirm your action in the dialog popping up. Sometimes this needs to be done twice. Alternatively you can allow the app in System Settings -> Security.
