Signs Your Finder Shell is Dying
I’ve got 39 days of uptime and just noticed that when I hit my Mute key, the little trasparent window would come up and flash the volume meter showing that there were no bars showing, but then bump back up to one bar, leaving the speaker on, but set to just one bar.
So I logged out and logged back in and my mute button works just fine. Logging out of the Finder and then back in is an easy alternative to rebooting the whole machine.
