Do more on your desktop
Make your desktop unique
Choose the look you want for your desktop. You can use a simple color, your favorite picture, or a scenic photo that changes with the time of day.
Access controls you use every day
Control Center gives you instant access to controls you use the most—like Wi-Fi, volume, and brightness—so you can easily adjust them as you’re working. Just click the Control Center button 
in the menu bar.
Get information at a glance
Your notifications and widgets appear in a single view in Notification Center, so you can easily see what your day has in store. You can also add the widgets you want, in three different sizes.
Take a screenshot
Use Screenshot on your Mac to quickly take a picture or recording of your screen to share with someone else.
Declutter your desktop
With Stacks, the files on your desktop are automatically organized into related groups—so you can keep all your content in tidy categories. Just click the desktop, then choose View > Use Stacks.
