Days before WWDC, Developer Steve Troughton-Smith discovered a 30-second preview video of the upcoming macOS 10.14. Apple seems to have accidentally leaked the video, which shows two prominent new features: a dark mode and a news app. Troughton-Smith tweeted some screenshots of the video.

The most recent version of macOS also has a dark mode but is only set on the dock and menu bar. Troughton-Smith also noted in his tweet the presence of an Apple News app icon and an App Store with video previews.
Apple’s WWDC kicks off this Monday, June 4th.
