Discover the Today view
Notification Center now includes a Today view with add-on widgets
One of the most noteworthy things about Yosemite is the way that OS X and iOS are not just working more closely together, but the desktop OS is adopting some of the best bits from the iPhone and iPad. The big revamp to Notification Center in iOS 8 has proven especially popular on mobile devices, enabling users to use the new Today view to see regularly accessed information, and add widgets to customise the experience.
This system has now come to OS X, providing at-a-glance views of calendar events, reminders, weather forecasts, stock prices, and more. It remains to be seen whether developers get behind the system as wholeheartedly as they have on iOS, but even though it’s still relatively early days we’ve already seen a number of very useful third-party widgets arrive in the Mac App Store. Here we’ll show you how to use these and Apple’s default widgets, along with the Today view in general.
Note that if you try out a lot of widgets, and then discard a bunch of them that you don’t actually want to stick with, OS X has a tendency to cache them in memory, even if you uninstall their parent apps. A restart fixes this, but it’s quicker to open Terminal and reboot Finder by typing the command ‘killall Finder’. Hit , and your Finder windows will briefly disappear and then reappear. When you open Notification Center, any uninstalled widgets will be gone. Alan Stonebridge
