I have the same error and found this. Core Audio - 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)

Solution: With OS X Sonoma 14.4 update there is no rights to relaunch coreaudiod - https://forums.developer.apple.com/forums/thread/748228?answerId=784882022#784882022

sudo killall coreaudiod

[krehel]

Yes, I patched the Cask files for blackhole-[2|16|64]ch to account for this after it was raised to our attention last month.

We had a discussion the other day about the solution, and someone was kind enough to write a small patch script - https://github.com/orgs/Homebrew/discussions/5291

[emindeniz99]

Thank you @klaushardt and @krehel, I solved my problem with removing the uninstall cask script from local file and kill coreaudiod manually.

I didn't search the issue in discussions, sorry for my mistake.

Manual editing is required for all users. Is it correct because there is not any method to update installed cask in local homebrew metadata?

[bevanjkay]

@emindeniz99 No there isn't, because the uninstall process can often change over time, so we use the version that matches the currently installed version. If you were to remove the cask's directory from the Caskroom, and use brew reinstall the latest uninstall script would be used instead.

[kyan001]

I uninstalled the old version by manually modified /opt/homebrew/Caskroom/blackhole-2ch/.metadata/0.5.0/20231116152617.059/Casks/blackhole-2ch.rb at line 18-23 from

                     "-kp",

[JavierCane]

Thx @kyan001!

I had to modify it as the new recipe states (commit):

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

                   ],

Yep this fixed the brew upgrade command for me.

My file was located at /opt/homebrew/Caskroom/blackhole-2ch/.metadata/0.5.0/20230911235106.162/Casks/blackhole-2ch.rb I assume this will be different for each system.

I recommend doing this in terminal:

1. Open terminal
2. Type: nano /opt/homebrew/Caskroom/blackhole-2ch/.metadata/0.5.0/
3. Press tab until you see blackhole-2ch.rb filled out. Which will probably be different if you have the 4 channel

[bevanjkay]

A potentially easier solution 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

[BrentSqAR]

I was running a second reinstall blackhole-64ch - and it was working. Thanks and have a nicce day

I followed bevanjkay -> it was working for blackhole-2ch and blackhole-16ch.

But not for: blackhole-64ch:

For intel mac, /usr/local/Caskroom/blackhole-2ch/ instead of /opt/homebrew/Caskroom/blackhole-2ch/

BlackHole was transfered during the migration from my Intel Mac to the Silicon Mac. It worked after these commands:

rm -rf /usr/local/Caskroom/blackhole-2ch/ Then install again brew install blackhole-2ch

bakcground-music had exactly the same issue, this file can be modified to fix it.

The worked for me if you dont include the "i" in rfi i.e.: rm -rf /opt/homebrew/Caskroom/blackhole-2ch/

Thanks all!

Has it been resolved? Or “won’t fix”?

The only way to globally resolve this would be to submit a PR to https://github.com/homebrew/Brew to detect and intercept the outdated kickstart command and replace it with the correct command. In future we would ideally replace these commands with a set of commands available through a Ruby DSL and not allow ad-hoc preflight/postflight blocks.

[devinroth]

The recommended command is retroactive if that makes any difference.

Closing this as workaround has been provided

[dddanielliu]

I tried all the above and its not working... (because my blackhole-2ch.rb doesn't exist) Then I figured out this workaround:

1. Disable SIP (System Integrity Protection) : go to Recovery Mode and type the following in terminal csrutil disable

2. Then go back to user: brew uninstall background-music

3. Enable SIP again: go to Recovery Mode and type the following in terminal csrutil enable

finally! this one worked. thanks!

[BlkPingu]

instead of this fix i had issues with I did something else:

1. Go into recovery mode (on M1 Mac shut it down, then start using the touch ID sensor, but hold it until you see "hold to boot into recovery mode" and release when you see "Booting into recovery mode", then log in your user, and open the terminal (utilities > terminal) from the menu bar

2. disable system integrity protection (SIP): csrutil disable and reboot

3. uninstall background music: brew uninstall background-music. it should work this time. and shut down the mac again completely

4. enable SIP again, follow the above steps, when in SIP terminal: csrutil enable and reboot

profit
