MacRumors has posted photos of what appears to be Mac OS X Snow Leopard packaging. The images show the outer casing as well as the DVD disc itself which would suggest that Snow Leopard is already in production.
Earlier last week it was claimed that build 10A432 of Snow Leopard was declared Golden Master. Despite Apple marking September has the launch month for Snow Leopard, sources have stated that August 28th looks like a more likely release date.
