How to Show Your Next Meeting in Your Mac's Dock
To see your next meeting in your Mac's Dock, add Moor's Next Event widget. Press Control-Option-E, choose Add in the toolbar, pick Next Event and drag it into place, then allow Calendar access when macOS asks. Apple's Calendar Up Next widget lives only in Notification Center or on the desktop and is read-only, so it can't put your meetings in the Dock (hora Calendar).
