Ever since Apple unveiled Siri for iOS, owners of computers running the company's Mac OS X have been wondering when the personal assistant would land on that platform too. And according to a new rumor on the matter, 2016 will be the year when this finally happens. Apple allegedly plans to make Siri the headline feature of the upcoming Mac OS X 10.12 release, which will probably be introduced initially at WWDC in the summer, and will then be rolling out in the fall. Apparently, there have been test versions of Mac OS X with Siri built-in since 2012, but only this year will the user experience be polished enough for Apple to launch this publicly. Siri for Mac will live inside the menu bar, in the right corner of it to be precise. The Siri icon placed there will activate the voice control feature. Once you click on the icon, you'll get a dark transparent interface similar to the one in the mockup above, complete with colorful sound waves which indicate speech input. Siri will also get its own pane in the Mac System Preferences, and you'll even have the option to choose a keyboard shortcut to activate it. And the "Hey Siri" command will work while the Mac is plugged in. Aside from Siri, the new Mac OS X version isn't said to introduce many new features, just minor UI tweaks here and there. Don't forget not to take any of this for granted however, because plans can change from now and until the announcement of Mac OS X...
