I love Do Not Disturb on my iPhone. I’ve got it scheduled to activate at 8 pm each night, and de-activate at 7 am every morning. That way, all except the most important things get to bother me when I’m with my family, in bed, and sleeping.
Mac OS X has a Do Not Disturb feature, as well, but it has to be manually activated at the top of the Notification Center by toggling the Show Alerts and Banners button to OFF. Wouldn’t it be cool if you could schedule it to turn off and on at specific times? The Automator script for Calendar below will do just that..
