Using a Retina display
Learn about the Retina display built into your Mac.
The pixel density of Retina displays is so high that your eyes can't detect individual pixels at a normal viewing distance. This gives content incredible detail and dramatically improves your viewing experience.

Changing the resolution of your display
Your Mac automatically chooses a default resolution that is optimal for your display. To change the resolution:
- Choose Apple menu > System Preferences.
- Click Displays.
- Select Scaled, then select any of the four or five scaled resolutions, depending on your Mac model. With scaled resolutions, text and objects can appear larger and more visible, or smaller to provide more space for windows and apps.
If you're also using an external display
If you're using an external display to extend your desktop, you can choose a preferred resolution for each display. To see additional resolutions for the external display, press and hold the Option key while selecting the Scaled button.
If you're using an external display to mirror your built-in display, your Mac optimizes for whichever display is selected in the ”Optimize for” pop-up menu. Allow your Mac to choose the best resolution for that display, or select Scaled and choose a different resolution.
Using apps with a Retina display
If an app looks different than you expect on your Retina display or high-resolution external display, try opening the app in low-resolution mode:
- Quit the app.
- Open the Applications folder.
- Click the app once to select it, then choose Get Info from the File menu.
- From the Get Info window that opens, select the checkbox labeled ”Open in Low Resolution.”
- Close the Get Info window and open the app again.
Some apps that work best in low-resolution mode or that work only in low-resolution mode will have this mode already turned on, and in that case you might not be able to turn it off. The app developer might offer an update that includes support for the Retina display.
Using Boot Camp and Windows with a Retina display
- Boot Camp supports resolutions up to 3840 x 2160.
- When your Mac is using the Apple-supplied Windows Support Software, Windows starts up with the maximum dpi (pixels) it supports, which is 144 dpi, or 150-percent magnification. As a result, items on the display appear small, with a lot of space. You can use the Windows Display control panel item to adjust this setting in Windows.
