The presence of Macs running OS X 10.9, Apple's next-generation operating system, continues to expand, potentially hinting that a public unveiling could occur soon.



From Apple Insider:

It was on February 16 of last year that Apple, for the first time, announced OS X 10.8 Mountain Lion. Now, nearly a year later, there is evidence that the company is hard at work testing the next version of its Mac operating system.

Traffic logs for AppleInsider show that visits from machines claiming to be running an unannounced OS X 10.9 spiked in the month of January.
