Verification

• My brew doctor output says Your system is ready to brew. and am still able to reproduce my issue.
• I ran brew update and am still able to reproduce my issue.
• I have resolved all warnings from brew doctor and that did not fix my problem.
• I searched for recent similar issues at https://github.com/Homebrew/homebrew-core/issues?q=is%3Aissue and found no duplicates.

What were you trying to do (and why)?

brew upgrade

This led to:

==> Updating Homebrew...
Already up-to-date.
==> Casks with 'auto_updates true' or 'version :latest' will not be upgraded; pass `--greedy` to upgrade them.
==> Upgrading 2 outdated packages:
blackhole-2ch 0.5.0 -> 0.6.0
upscayl 2.10.0 -> 2.11.0
==> Upgrading blackhole-2ch

Error: Problems with multiple casks:
blackhole-2ch: 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

Trying to uninstall:

brew uninstall blackhole-2ch

I got the same error, see below.

What happened (include all command output)?

==> Uninstalling Cask blackhole-2ch
==> Uninstalling packages with sudo; the password may be necessary:
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

What did you expect to happen?

Clean uninstallation.

Apparently under Sonoma 14.4, this is a known issue?

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)

Step-by-step reproduction instructions (by running brew commands)

See above

[slhck]

sudo killall coreaudiod

seems to do the job. I see that the formula was fixed in Homebrew/homebrew-cask@d6de09e — but apparently it's impossible to upgrade it?

Ah, I looked in the wrong repository. Closing in favor of Homebrew/homebrew-cask#171570
