Enable OS X Yosemite’s Incomplete Dark Mode with a Terminal Command
Apple unveiled a new “dark mode” for OS X Yosemite during the company’s WWDC keynote earlier this month, but the feature has thus far been absent from the first two developer builds. Today, however, developer Hamza Sood discovered that a partially-functional Dark Mode could be enabled in the second Yosemite beta with a Terminal command.
To try the feature, head to Terminal on a Mac running OS X Yosemite Beta 2 and enter the following command:
sudo defaults write /Library/Preferences/.GlobalPreferences AppleInterfaceTheme Dark
This implementation gives developers a peak at the final version of Dark Mode, although in its current form it is incomplete, with several bugs readily apparent. To disable Dark Mode and revert to the default Yosemite color scheme, head back to Terminal and use this command:
sudo defaults delete /Library/Preferences/.GlobalPreferences AppleInterfaceTheme Dark
If the above command doesn’t work, try this:
sudo defaults write /Library/Preferences/.GlobalPreferences AppleInterfaceTheme Light
You’ll need to log out of your user account or reboot your Mac to see the change in either case.
