I see the PR to fix this in homebrew-cask is merged, but doing brew update does not seem to fix this issue, is anything else necessary?

[musse]

@DamianPereira Even after the homebrew-cask fix was merged, there was a "cached" copy of the background-music.rb file (I don't remember the exact path), I had to manually edit it to match the fixed file to be able to uninstall it.

Thank you! I'll check it out.

ok manually editing /opt/homebrew/Caskroom/background-music/.metadata/0.4.0/20231226055056.585/Casks/background-music.rb with the patch did let me uninstall

Can you help me with this? What exactly do I need to edit in this file? I'm just trying to update but that's not possible when I cannot uninstall

@lead0r Is this what you're looking for? https://github.com/Homebrew/homebrew-cask/pull/169322/files

Yes, thank you, that worked!

Can anyone please say how they managed to fix this issue? This is the formula on my Mac that is causing the problem:

cask "background-music" do
  version "0.4.3"
  sha256 "c1c48a37c83af44ce50bee68879856c96b2f6c97360ce461b1c7d653515be7fd"

  url "https://github.com/kyleneideck/BackgroundMusic/releases/download/v#{version}/BackgroundMusic-#{version}.pkg"
  name "Background Music"
  desc "Audio utility"
  homepage "https://github.com/kyleneideck/BackgroundMusic"

  livecheck do
    url :url
    strategy :github_latest
  end

  pkg "BackgroundMusic-#{version}.pkg"

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

  uninstall launchctl: "com.bearisdriving.BGM.XPCHelper",
            quit:      "com.bearisdriving.BGM.App",
            pkgutil:   "com.bearisdriving.BGM",
            delete:    [
              "/Library/Application Support/Background Music",
              "/Library/Audio/Plug-Ins/HAL/Background Music Device.driver",
              "/usr/local/libexec/BGMXPCHelper.xpc",
            ]

  zap trash: [
    "/Library/LaunchDaemons/com.bearisdriving.BGM.XPCHelper.plist",
    "~/Library/Preferences/com.bearisdriving.BGM.App.plist",
  ]
end

I tried editing it to remove the lines @kyleneideck linked, but then the hash changes and brew won't use it.

Edit: GPT-4 helped! I followed suggestion #2 and it got rid of this app once and for all.
