According to 9to5Mac, early builds of the OS X 10.9 include versions of Siri and Apple Maps for the Mac.
The site writes that it isn’t certain whether the two features will go past the early testing stages and if that happens, they could be features only brand-new Macs would support.
The Dictation feature on the OS X 10.8 Mountain Lion is seen as an indicator of the possible integration of Siri.
AppleInsider recently reported seeing over 30 total visits in their online tracking log from machines running the OS X 10.9 in the past few weeks.
The site wrote that the data may be fake, but says that the “timing and IP addresses are in line with what we expect from beta testers of the next version of Mac OS.”
