How to automatically hide notifications after a timeout in OS X Sierra?

Question

Is it possible to configure the notifications that they disappear after a timeout in OS X Sierra?

Currently they never disappear until I click on them, which is super annoying. I can't find any settings in the UI to configure this.

Answer 1

System Prefs > Notifications
On a per-app basis, you need to switch from Alerts to Banners ...

Banners appear in the upper-right corner and go away automatically. Alerts stay on screen until dismissed.

Answer 2

According to this Apple Developer Manual entry, in AppleScript you programmatically dismiss an alert after a specified period of time.

display dialog "Do, or do not. There is no try." giving up after 5
--> Result: {button returned:"OK", gave up:true}
