I'm hoping that someone can help me please. I was adding cities into the Weather app in notification centre and accidentally clicked on the wrong city. I clicked High Wycombe, Australia, not High Wycombe, England. I tried to remove it from the app by clicking the little red minus sign and it goes away. However, about 15 seconds later notification centre brings it back and shows it at the top of the list. I've tried restarting the Mac. I've gone to activity monitor and used the quit process button to quit notification centre in the hope it'd restart fine. I've also used terminal and typed "killall NotificationCenter" all with no luck whatsoever. It still keeps bringing back the city I don't want. Anyone any other suggestions on what I can do please?
