问题 I'm writing an app in swift that lives in the menu bar at the top of the screen. I need both a global and local event monitor to open the popover on a specific key press. There is no problem with the local event monitor, but when the user hits the key command (cmd+shift+8) from inside an app like Finder, the popover opens but the mac error "Funk" sound is played as well. Is there any way I can disable this? Perhaps some way for the app to eat the sound, or register it as a valid keyboard
