I uninstalled the Boom application, I can’t find any files related to Boom in my system—maybe I am missing something?—but I still have this in my output devices configuration:

enter image description here

How can I delete the Boom output device in those configurations?

  • Check for BoomDevice.kext in /System/Library/Extensions.  If present, delete it.
  • Delete Boom app [if you didn't already].
  • Reboot.
  • Confirm that BoomDevice has been removed from System Sound Preferences.

Open Terminal app and run the following command(s)...

  • To remove BoomDevice
sudo kextunload -b com.globaldelight.driver.BoomDevice
  • To remove Boom2Device
sudo kextunload -b com.globaldelight.driver.Boom2Device

This should do the trick and you even don’t need to reboot your Mac.

    FYI it's now two years later and somehow that driver keeps came back. I re-ran this command also Tom's command from another answer (rm -rf ~/Music/Boom{,\ 2}) - fingers-crossed! – subelsky Nov 7 '18 at 20:42

Execute the following commands in a (bash) terminal window.

To uninstall Boom (v1) and remove BoomDevice:

killall Boom
sudo kextunload -b com.globaldelight.driver.BoomDevice
sudo rm -rf /Applications/Boom.app /Library/Extensions/BoomDevice.kext

To uninstall Boom2 and remove Boom2Device:

killall Boom\ 2
sudo kextunload -b com.globaldelight.driver.Boom2Device
sudo rm -rf /Applications/Boom\ 2.app /Library/Extensions/Boom2Device.kext
killall com.globaldelight.Boom2Daemon

You do not need to reboot, the effect is immediate.

Further, to wipe out Boom's profile(s)/config settings (e.g. if you don't plan on reinstalling Boom in future, or want to have a clean slate if you do decide to), you can finally execute:

rm -rf ~/Music/Boom{,\ 2}

    Jan 2018 - Updated this to include removal of an additional Boom2 service, and removal of profile/configuration data – Tom Jan 9 '18 at 13:57
  • This is the best answer, IMO – OMA Mar 3 at 22:30

You can use Uninstall Boom Device script from it's creators. It simply runs these commands:

sudo kextunload -b com.globaldelight.driver.BoomDevice
sudo rm -rf /System/Library/Extensions/BoomDevice.kext
sudo rm -rf /Library/Extensions/BoomDevice.kext

Tetsujin's answer is not correct actually, the Kernel Extension file is not in /System/Library/Extensions but in /Library/Extensions and it's called Boom2Device.kext – you have to delete this one to get rid of the Boom2Device.
