After updating to the latest iteration of High Sierra (10.13.6) on my MacPro (cheesegrater) this afternoon, I cannot load my Sound Preference panel nor get any sound to display.
Activity Monitor reports:
com.apple.preference.sound.remoteservice (Not Responding)
FWIW, I have a speaker connected to the optical digital port, plus I have an Apple LED Cinema display connected. Both worked fine before this morning.
Where do I begin to troubleshoot this?
I tried a Safe Boot, but same behavior, also logged in as another Admin user, same result. I also deleted com.apple.systempreferences.plist
