  1. Open Xcode.
  2. Choose Xcode > Open Developer Tool > More Developer Tools.. Choosing this item will take you to developer.apple.com.image: ../Art/gettools_2x.png
  3. Sign in to developer.apple.com. You should then see the Downloads for Apple Developers webpage.
  4. Download the Graphics Tools for Xcode package, which contains Quartz Debug.

Once you have successfully installed Quartz Debug, you’re ready to enable HiDPI modes on your Mac. Here’s how it’s done:

  3. Select “Enable HiDPI display modes”.
