Describe the bug

I cannot uninstall Blackhole from macOs 15.4.1

I've tried multiple independent methods mentioned on the site:

• First, do a clean install of BH 2 ch
• using the generic "automated uninstaller" on this page: https://github.com/ExistentialAudio/BlackHole/wiki/Uninstallation . Get error "The installation failed."
• using the manual steps at the above link -- there is no blackhole driver in /Library/Audio/Plug-Ins/HAL even tho blackhole appears in the Audio MIDI Setup app and other apps.
• using a specific blackhole2ch uninstaller listed here: https://existential.audio/blackhole/support/ . Installation succeeds but blackhole remains installed.

I'd really appreciate support on how to uninstall this as i believe its presence is interferring with another audio app on my system.

thank you

Reproduction Steps

etc...

Expected Behavior

blackhole is uninstalled with the provided method or uninstaller

Have you tried rebooting?

A while ago macOS changes under the hood made the installer/uninstaller report failure but it actually just needs a reboot.

@devinroth The installer was updated to require a system restart. Maybe the uninstallers should as well?

@orchetect that did the trick! Thanks :)

Im having the same issue. Just restarted my computer but didn't change anything. I'm on Sequoia 15.4.1 Cannot download uninstall package, cannot run uninstall on terminal as written in the guide.

What errors are you getting in terminal?

Via brew I'm getting:

brew uninstall blackhole-16ch
==> Uninstalling Cask blackhole-16ch
==> Uninstalling packages with sudo; the password may be necessary:
Password:
Could not kickstart service "com.apple.audio.coreaudiod": 1: Operation not permitted
Error: Failure while executing; `/usr/bin/sudo -E -- /bin/launchctl kickstart -kp system/com.apple.audio.coreaudiod` exited with 1. Here's the output:
Could not kickstart service "com.apple.audio.coreaudiod": 1: Operation not permitted

From the pkg I also see the same error.

It did eventually work for me. Despite error in terminal (As posted above by carlos-matiro). When I restarted my computer, Blackhole had finally disappeared. It's confusing since the terminal says "error" "failure" "not permitted" and there is no message confirming it worked.

I had this problem affecting affecting the BlackHole64ch.driver when running the uninstaller in macOS 14.7.6. It just didn't work, with our without reboot. The manual cd /Library/Audio/Plug-Ins/HAL && sudo rm -rf BlackHole64ch.driver && killall -9 coreaudiod in Terminal worked fine.
