Using a Retina display
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.
Computers and external displays with a Retina display
Native resolution, pixel density, and color depth vary by product model. Use the links below to find the tech specs for your Model.
MacBook Pro models introduced in late 2012 or later, and MacBook Pro (Retina, 15-inch, Mid 2012)
MacBook Air models introduced in 2018 or later
MacBook models introduced in 2015 or later
iMac and iMac Pro models introduced in late 2014 or later, except iMac (21.5-inch, Late 2015) and iMac (21.5-inch, 2017)

Using Mac apps with a Retina display
If an older app looks different than you expect on your Retina display or high-resolution external display, you might be able to open 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,” if present.
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.
