Notification Banner

I’ve recently found myself wishing there was a space between banners and alerts with OS X’s notification system. Alert style notifications that require manually dismissing can be rather annoying, but quick banner notifications often fly by before I’ve had time to glance at the information. It turns out despite not having a toggle in the system preferences, a little Terminal code shared by OS X Daily allows you to toggle the duration down to the second…

Ported from iOS, Notification Center is intended to catch all these notifications in one central location for skimming, but it’s a messy place without a lot of customization.

Notifications in System Preferences does offer a number of customization settings, but banner duration is noticeably absent from the preference pane.

NotificationsTo get around this and change the banner duration, open Terminal and paste in the script “defaults write bannerTime #” with the number sign replaced with the amount of seconds you want banner notifications to stick around, then log off and back on.


If you decide to alter the duration back to OS X’s default choice, simply paste “defaults delete bannerTime” and log off and back on again.
