9to5Mac claimed back in January that Siri would be finally coming to the Mac via the forthcoming OS X 10.12 software update this fall. Today, MacRumors published a genuine looking image that purportedly shows a colorful Siri icon sitting in OS X's Dock, adding fuel to the Siri for Mac rumors.
Another screenshot appears to show a Siri icon sitting in the Mac's menu bar at the top. The publication says that these screenshots were sent to them by a source “who has provided us with reliable information about Apple's software plans in the past”.
