Update your OnSong® AuxBox
Download the updater for your computer, connect your AuxBox over USB, and follow the on-screen steps. It takes about a minute.
Version 1.2.2. One macOS download works on every Mac.
On Linux, make the AppImage executable (chmod +x). If the AuxBox is not detected, add your user to the “dialout” group — sudo usermod -aG dialout $USER — then log out and back in.
