Apple seeds OS X 10.10 Yosemite Developer Preview 3 with Dark Mode and other interface tweaks

Besides the third beta of iOS 8, Apple also released a new developer preview of OS X Yosemite. The update is available in the Mac App Store and under Software Update.


The upcoming OS is still very much in the beta process, as Apple continues to make interface tweaks and add features.

Dark mode

Most notably, Dark Mode can now be enabled easily in System Preferences. The feature, demoed by Apple at WWDC last month, was previously hidden and required some tinkering with terminal to turn on.
