Apple's as yet unreleased Mac OS X 10.7 has suddenly been picking up in web traffic in recent days and suggests rapidly advancing testing. After only a relatively small level of traffic late in 2009, numerous web logs in recent days have shown many more systems browsing to sites and identifying themselves as 10.7 in their user agent strings. Most of these continue to come from the 17.x.x.x IP address block associated with Apple's offices, but they are now also coming from outside the company or in other countries.
