Describe the bug

Hi, I'm not sure if this belongs here or in the Discussions section, but I'm trying to uninstall Blackhole 2ch, but I must've messed something up somewhere previously, because neither the uninstaller app nor the manual instructions work to uninstall it.

When trying to install the uninstaller app I get the error "The installation failed. The installer encountered an error that caused the installation to fail. Contact the software manufacturer for assistance."

When trying to uninstall manually there is no HAL folder at all under /Library/Audio/Plug-Ins/HAL and the sudo commands listed on this page: https://github.com/ExistentialAudio/BlackHole/wiki/Uninstallation do not seem to do anything.

Blackhole 2ch is still listed under Audio MIDI setup, Settings > Sound > Output & Input as well as in a couple other apps I use like Ableton and eqMac.

I tried reinstalling Blackhole as well, but get the same error as using the uninstaller app, which is "The installation failed. The installer encountered an error that caused the installation to fail. Contact the software manufacturer for assistance."

Any help would be greatly appreciated. Thanks!

Check to make sure "Installer" has File and Folder permission and Full Disk Access in System Settings->Privacy and Security.

Hi @devinroth, I don't actually see "Installer" Listed in the File and Folder or Full Disk Access lists. How do we add it?

Screenshots please. And have you tried restarting your computer? Devin

Also running into this issue...

1. there is no driver related to blackhole in /Library/Audio/Plug-Ins/HAL:

❯ ls -lah
Permissions Size User Group Date Modified    Name
drwxr-xr-x     - root wheel 2022-11-28 16:31  MSTeamsAudioDevice.driver/
/Library/Audio/Plug-Ins/HAL ❯                                                                                                                 03:58:45 PM

2. both blackhole drivers still show in Audio/Midi devices, apps, etc:
   

3. when trying to run the uninstaller, it errors:

Try just restarting your computer. Devin

Use the manual uninstall method rm -R /Library/Audio/Plug-Ins/HAL/BlackHoleXch.driver (replacing 'x' with version).
Followed by sudo killall coreaudiod instead of sudo launchctl kickstart -kp system/com.apple.audio.coreaudiod to restart the service. Source: https://forums.developer.apple.com/forums/thread/748228

I installed it with Homebrew and uninstalling it the same way would not remove it from brew list so I also had to delete its' folder from /opt/homebrew/Caskroom

Having the same issue now, even downloading the latest version...

Has anybody found a fix?

[devinroth]

Yeah. It’s already in the discussions. Devin

Check if you have the right uninstaller, you can download the uninstaller here: existential.audio/blackhole/support. If you installed BlackHole 2ch, remove it with uninstaller 2ch.

I had the same problem of having uninstallation failure. I thought it was a well-hidden malware, and was gonna stuck there forever. I made a mistake of uninstalling the wrong version. So check if you got the wrong uninstaller; if so, get the right one.

[ihafkenschiel]

This worked for me. Thanks!

Running into this issue as well, attempted manual removal, it says that it's gone, used the correct 2ch uninstaller, fails every time. Despite all this, it still shows up as an audio source.

Just reboot you computer! It solved the issue for me.

[davidrgmcb]

Tried it, sadly no luck.

[devinroth]

Rogue Ameoba’s ACE driver has been messing with CoreAudio. If you have that installed remove that and see if it fixes the issue. Devin

Removing the ACE driver did allow me to remove blackhole, thank you so much.
