Apple detailed Mac OS X v10.6., a.k.a. Snow Leopard, back at its Worldwide Developers Conference (WWDC) in June, but has since remained reluctant in providing a specific launch date.
The company had previously stated that Snow Leopard would become available to Mac OS X customers sometime this September at an upgrade cost of just $29 for a single user license, and $49 for a five-user family pack, but a brief listing on the UK Apple Store earlier today suggests otherwise. According to the listing, Apple's operating system refresh will land on August 28th - seven days from now.
Apple hasn't officially commented on the supposed slip, but it appears the software could become available sooner than the original September timeframe, albeit by a matter of days.
Whilst demonstrating the software at its WWDC earlier this year, Apple referred to the rival Windows 7 operating system from Microsoft as the "same old tech as Vista", whilst claiming that Snow Leopard is "the world's most advanced operating system".
