Switching to HiDPI mode

1 Enable HiDPI

In Terminal, enter: sudo defaults write /Library/Preference s/com.apple.windowserver.plist DisplayResolutionEnabled -bool

true followed by ® . You’ll then need to enter an admin account’s password. Afterwards, when you see the command prompt again, log out of your account, and then log in again.

2 Select a HiDPI otption

Open System Preferences and click the Displays icon. Hold down å and click on the Scaled option to reveal a list of resolutions. Several are marked as ‘low resolution’. If you select one of those options, the desktop will be proportioned for that resolution, but it will be rendered in HiDPI mode, so it will appear sharper than normal.

3 Quickly switch modes

You can switch between HiDPI and normal resolutions in the Displays pane at any time. If you find yourself doing so frequently, try SwitchResX (free, madrau.com). This adds an icon to the menu bar that enables switching between resolutions in a couple of clicks – something that Apple used to allow from the Displays menu extra but took away!
