One of the flagship features in Apple’s new OS X Mountain Lion is Notification Center, a way to manage notifications from the various apps on your Mac. Though relatively straightforward, there are several ways to customize your experience.
Notification Center works in two ways. First, a banner will appear in the upper right of the screen when an app creates an alert.
Second, a list of all recent notifications can be found in the Notification Center. To access the Notification Center, click on the right side of the menu bar at the top of the screen, or swipe two fingers across the right side of your trackpad toward its middle.
Clicking an alert listed in Notification Center will launch the related app and take you to the related event. Support in Notification Center is dependent upon the developer, but currently Calendar, Mail, Twitter, and many third party apps make use of it.
Notification Center allows you to customize what apps give notifications and how they are given. This can be adjusted by clicking the Apple on the left of the menu bar at the top of the screen, then choose SYSTEM PREFERENCES. In the system preferences, choose NOTIFICATIONS.
Choose the app that you’d like to adjust from the list on the left, then make adjustments on the right.
If you ever want to temporarily stop all notifications, you can enter into Do Not Disturb by either holding the Option key while clicking , or by scrolling all the way to the top in Notification Center and swiping the SHOW ALERTS AND BANNERS slider to the left.
Notifications will resume the next day, or if you manually leave Do Not Disturb by repeating the steps above.
