CUPERTINO, Calif. (AP) — Apple is inviting media to its Cupertino, Calif., headquarters for a Macintosh computer-related event Oct. 20.

Apple Inc. is known for its secrecy about upcoming products. The invitation sent todayoffers no concrete details about the products to be announced. It does show an image, however, of Apple's logo opening like a door to reveal a glimpse of a lion.

That's a clue that Apple plans to introduce a new version of Mac OS X, the operating system software that runs on the company's desktop and laptop computers. Apple calls its Mac computer operating system updates by names of large cats. The most up-to-date version is Snow Leopard. Previous versions include Leopard, Tiger and Panther.
