Apple says it’s introducing a laptop with a super-high resolution “Retina’’ display, setting a new standard for screen sharpness.

The new MacBook Pro will have a 15-inch screen and four times the resolution of previous models, Apple CEO Tim Cook told developers at a conference in San Francisco.

Apple already uses “Retina’’ displays — with individual pixels too small to be distinguished by the naked eye — in its latest iPhones and iPads.

The new MacBook will cost $2199 and up, and is part of a general revamp of Apple’s personal computer line announced Monday.

Apple CEO Tim Cook is expected to show off new iPhone software, updated Mac computers and provide more details on future releases of Mac software when he kicks off the company’s annual conference for software developers on Monday.

The announcement of new software for the iPhone, iPad and iPod Touch has been confirmed by banners that appeared at the Moscone conference center in San Francisco on Friday, reading “iOS 6.’’ It’s not much of a surprise. Apple has used its Worldwide Developers Conference as an opportunity to announce new iPhone software for the past few years.

What’s not known is what new features will come with iOS 6, or when it will be released to consumers. Usually, the new software becomes available for download around the time a new iPhone model appears. Apple-watchers expect the next version of the iPhone, the iPhone 5, to appear this fall, about a year after the launch of the 4S model.

In 2010, Apple demonstrated the new iPhone 4 at the WWDC, but analysts don’t expect the company to show off a phone model this year.

With the launch of iOS 5 last year, Apple added many features already found in competing smartphone software. It also added the “Siri’’ virtual assistant feature, which interprets voice commands and talks back to the user.
