 Replying to [comment:1 ryandesign]:
 > According to the mpd homepage, the latest version of mpd is 0.23.15.
 >
 > 13.0.1 appears to be the latest version of some other software called
 myMPD. The port's livecheck should be improved to return results only for
 mpd version numbers.

 > According to buildbot logs, the build failure on macOS 11 is due to the
 use of `kAudioHardwareServiceDeviceProperty_VirtualMainVolume` which was
 [https://developer.apple.com/documentation/audiotoolbox/1405208-audio_hardware_services_properti/kaudiohardwareservicedeviceproperty_virtualmainvolume?language=objc
 introduced in macOS 12], so indeed mpd 0.23.8 is not compatible with macOS
 11 or earlier and this isn't in our control. You can check if the latest
 upstream code still uses
 `kAudioHardwareServiceDeviceProperty_VirtualMainVolume`; if so, then it
 still requires macOS 12 or later and the port should be marked as
 requiring macOS 12 or later using the `platforms` keyword. You can file a
 ticket with the developers asking them to support earlier macOS versions
 if you wish but they may not want to do that and it's not our job to
 maintain complex patches for old OS compatibility; it's only our job to
 offer an easy way to install the software the developers provide.

 Of course, I did not mean that anyone ''has to'' fix it. This was just to
 bring attention to the issue. I will open a ticket with upstream.

 Thank you for fixing livecheck.
