Okay, so I trashed the Logic Pro preference files in: ~/Library/Preferences/com.apple.logic10.plist ~/Library/Preferences/com.apple.logic.pro.cs This meant I had to re-adjust my Logic preferences (including any custom keyboard shortcuts), but at least the question mark (and other devices) are now gone from the MIDI > Inputs tab. If in any case I see the "Error initializing Core MIDI" again, I will post it here. For now this topic can be marked as solved.

PS I don't see anything mysterious in my Audio MIDI Setup app: Furthermore, I have checked: /Library/Audio/MIDI Configurations/ (empty) /Library/Audio/MIDI Devices/ => only 'Generic' folder inside, which I believe is default /Library/Audio/MIDI Drivers/ (empty) /Library/Audio/MIDI Patch Names/ (empty) And in my home folder: ~/Library/Audio/MIDI Configurations/Default.mcfg => containing 4 items for the drivers: com.apple.AppleMIDIRTPDriver com.apple.AppleMIDIIACDriver com.apple.AppleMIDIBluetoothDriver com.apple.AppleMIDIUSBDriver (for my Keystation Mini 32 MK3 USB keyboard) [*]~/Library/Audio/MIDI Drivers/ (empty)

Hi all, After sometimes (irregularly) seeing an error "Error initializing Core MIDI" when starting up Logic, I noticed there's a question mark item in my MIDI > Inputs tab in the Preferences: Any idea how I can get rid of this empty/question mark entry?
