Apple's Mac userbase has grown to 66 million users, the company announced today at its Worldwide Developers Conference.
The company, which also unveiled new MacBook Pros and a MacBook Air at the event, says that it has sold 26 million copies of Mac OS X Lion since its launch last summer, and 40 percent of its users are running that operating system.
That 40 percent figure proved important to Apple. During its keynote, the company said that it took Microsoft's Windows 7 platform 27 months to hit the same penetration rate as Lion, which needed only nine months to hit the mark.
Moving away from Mac OS X, Apple also said today that it now has 125 million registered iCloud users syncing data across mobile products and computers.
