Hi @Andrew
I'm having the same problem, I added the Recovery to the blacklist but it still shows another volume. It's name is Macintosh HD - Data it's directory is com.apple.TimeMachine.localsnapshots it shouldn't show up in the eject option because as @paulw have, I have the com.apple.TimeMachine* in the blacklist. I tried adding com.apple.TimeMachine.* but it still shows the Macintosh HD - Data. Any idea on how to solve this?
Best Regards,
Pedro
