Apple CEO Steve Jobs talks in June about the release of Mac OSX Leopard operating system.

Apple Inc., seeking to spur demand for its personal computers, will release the latest version of the Macintosh operating software next week, after delaying the product to finish the iPhone.

The software, called Leopard, will go on sale Oct. 26 for $129. A family edition costing $199 will allow five people in one house to use the program, Apple, based in Cupertino, Calif., said Tuesday in a statement.

Leopard may help boost Mac sales by offering new features for organizing and sharing files, as well as software that lets users run Microsoft Corp.'s Windows. Apple, which also makes the iPod, sold a record 1.76 million Macs last quarter as customers bought models with faster chips from Intel Corp.

"If you like elegance and simplicity, you're going to be happier in the Apple environment," said Roger Kay, an analyst with Endpoint Technologies Associates in Wayland, Mass. "If you like flexibility, you're going to be happier in the Windows environment. That's always been the difference between Apple and Microsoft, and it hasn't changed."
