Mac has finally put the OS X Snow Leopard up on their website, this OS replaces Leopard. The main differences between Leopard and Snow Leopard are speed and requirements. The UI will look about the same but there is now faster, more stable, 64 bit versions of Mail, iCal, Safari, iChat, Finder, and QuickTime X. My favorite part is that Microsoft keeps getting fatter and slower… not Apple… the new OS X Snow Leopard uses 7GB’s less hard drive space than Leopard.
