When I upgraded OS X to Mavericks I found that Final Cut Pro X alerts got more annoying. Every time I exported a movie from my edit, I would get an alert when the background export finished. When I need to export many movies in a short period of time, I end up with a whole series of alerts:

To prevent Final Cut – or any OS X application – being so ‘chatty,’ go to System Preferences and choose the Notifications pane.

Scroll down and click ‘Final Cut Pro.’

Change the alert style from Alerts to Banners. Instead of having to dismiss each alert, banners go away automatically.
