Siri will make its long-anticipated debut on Mac in OS X 10.12 later this year



From MacRumors:

When a user clicks the Siri button, a dark, transparent Siri interface will appear in the top right corner of the screen, as shown in our mockup by Michael Steeber. This interface will feature colorful sound waves to indicate speech input. The interface design in testing is not finalized and may still change before the summer introduction, according to sources.When the Mac is connected to power, users will also be able to make "Hey Siri" voice commands akin to the latest iPhones and iPads. Siri is expected to be one of the headline features of OS X 10.12, codenamed "Fuji," alongside other minor user interface tweaks. The changes will allegedly not be as significant as OS X Yosemite in 2014.
