Uninstall is not working too.

[devinroth]

Kickstart no longer works. We updated this. I suggest opening an issue with home-brew since I think it’s related to older versions using that command.

Okey, I will try contact brew. Still you've got readme to update. There are still kickstart commands.

[devinroth]

Thanks for the reminder. Feel free to @ me on the homebrew issue.

@devinroth @BetterB0y Sorry you lost me a bit. I don't see anything in the readme about updating. Do I have to uninstall and reinstall? it would be great if homebrew was fixed. I really prefer using that to handle this stuff when possible.

[BetterB0y]

@mbierman Command is still in readme. It's not resolving anything about this issue.

I found a way to workaround this:

You go to the Caskroom for the cask, on Apple Silicon macs, it is here:

/opt/homebrew/Caskroom/blackhole-2ch/.metadata/0.5.0/

On Intel Macs, it is here:

/usr/local/Caskroom/blackhole-2ch/.metadata/0.5.0/

And you will see a folder with a date, cd into it, you will see the blackhole-2ch.rb

Edit it that file, change

system_command "/bin/launchctl",
                   args:         [
                     "kickstart",
                     "-kp",
                     "system/com.apple.audio.coreaudiod",
                   ],
                   sudo:         true,
                   must_succeed: true

to

system_command "/usr/bin/killall",
                   args:         ["coreaudiod"],
                   sudo:         true,
                   must_succeed: true

Then save the file, and then uninstall should success.

@gnattu it worked for blackhole-2ch. What about blackhole-16ch? Is it okey to just delete blackhole-16ch dir from Caskroom?

No, you do the same for the blackhole-16ch.rb to replace the system_command

[BetterB0y]

There is .pkg file only there. No .rb file

[gnattu]

The .metadata folder is a hidden and you cannot navigate into it using finder directly. You replace the path and cd into it directly.

[BetterB0y]

Thanks. It worked. I used cd but something weird happened and i wasn't in .metadata dir.

[rubincc]

Thanks @devinroth and @gnattu. After brew remove (following your suggestion) I did a brew install and now everything works.

[WolfLink]

To be it clear, you can run "brew upgrade" after editing blackhole-2ch.rb to successfully upgrade to the latest version (which should then upgrade fine in the future).

A potentially easier solution, that makes it less likely to leave the cask file in an unreadable state is to remove the file from the Caskroom and then reinstall it.

This will cause Brew to use the most up-to-date uninstall stanza, instead of the one that was present when the installed version was installed.

Silicon Mac rm -rfi /opt/homebrew/Caskroom/blackhole-2ch/

Intel Mac rm -rfi /usr/local/Caskroom/blackhole-2ch/

Then reinstall brew reinstall blackhole-2ch

This oddly didn't work for me as it just downloaded 0.5.0 to run uninstall first which failed. The previous fix of patching the .rb file did work though.

That's the solution at list with 2ch:

Known Issues To improve security and stability, using launchctl kickstart -k is no longer permitted for critical system processes. If a process must be forcefully terminated, it is recommended to use kill instead. (123028502)

https://developer.apple.com/documentation/macos-release-notes/macos-14_4-release-notes#Core-Audio

If remove the -k parameter works fine.

[booi]

If remove the -k parameter works fine.

I don't think that's right. What we need is for coreaudiod to restart which we were doing with launchctl kickstart -k. Merely removing the -k will mean it won't restart coreaudiod.

I think the correct solution is here: https://github.com/ExistentialAudio/BlackHole/issues/779#issuecomment-2058581435 . Since coreaudiod is considered a core service, it will restart if killed.

This is not just a homebrew issue, the 2ch uninstaller .pkg in the README fails, and so do the commands provided in that same README

I had originally installed via the 2ch installer .pkg provided through the existential.audio site

[devinroth]

It’s a combination. It depends on which command you use.

To manually uninstall remove BlackHole from Hal and then restart. If that doesn’t work make sure you uninstall Rogue Amoeba’s apps since they mess with CoreAudio.
