How to Get started with Today view
1 Notification Center
To access Notification Center, click the icon on the far-right of the menu bar. It slides across, above other content. As in iOS, you get a Today tab for time-sensitive info and widgets. You can scroll up and down if needed.
2 Get started with editing
The Weather app will ask for permission to use your location; click OK in the Weather widget. Click Edit (at the foot of the panel) to expand Notification Center to see installed widgets (left) and those you can add (right).
3 Switch some widgets
Widgets can be changed via drag and drop or using the +/– buttons. Try removing Stocks by clicking its – button; it moves to the right-hand pane. Drag the handles at the right of widget titles to reorder your widgets. 4 Customize a widget
Click Done to stop editing, then move your pointer over the World Clock widget, and click the “i” to put the widget into edit mode. Click Add to create a new clock, then select a location for it. Drag the clocks to reorder them. 5 Access weather details
Some widgets, such as Weather, provide more info when interacted with. By default you see current conditions, but click a location and an extended forecast is provided, showing the next few hours and also the coming days. 6 Third-party widgets
The Today view is extensible, which means you can add third-party widgets installed via the Mac App Store. When a new widget is detected by your Mac, the Edit button will alert you to new items. 7 Add third-party widgets
You add third-party widgets in the same way as the built-in ones, and some may need configuring. Note that Today view is primarily designed for “at a glance” information that’s important to you, so don’t go too crazy. 8 Interact and experiment
Some third-party widgets may interact with their parent apps. For example, if you use the Countdowns widget to set reminders, you’ll need to click the Settings button next to Add to open the main app to edit any timers.
