Evidence is piling up that Apple is upgrading its MacBooks to include the Retina display currently available on the iPhone 4S and new iPad.
For starters, The Next Web noticed that a Mac OS X application called FolderWatch was updated Friday in the Mac App Store with support for "Retina graphics" - even though Macs do not currently support the upgraded screens. FolderWatch, available for £7.99, monitors and synchs important files automatically.
"Apple just approved FolderWatch 2.0.4. The app is ready for Retina displays and comes with a couple of handy new features," app maker Brothers Roloff tweeted yesterday.
In subsequent tweets, however, the company denied having any insider information about Apple's MacBooks. "By 'retina graphics' we're simply referring to HiDPI (a.k.a. @2x graphics). We don't know what Apple will show at WWDC," the company said.
Rumours have been swirling for months that Apple is readying a new line of MacBooks featuring a Retina display. The new line could be unveiled as early as next week, when Apple kicks off its annual World Wide Developer's Conference in San Francisco. The Cupertino tech giant is scheduled to hold a keynote address on Monday at 18:00 GMT (10:00 PST).
A list of purported part numbers obtained by AppleInsider this week suggested that Apple is planning to update almost its entire Mac lineup, including the 15-inch MacBook Pro, the 11- and 13-inch MacBook Air models, and iMacs. All are said to be getting Retina displays.
Also adding fuel to the rumours, images of a purported MacBook Pro spec sheet hit the Web earlier this week, showing a much higher-resolution display. According to the unconfirmed label, posted by 9to5Mac.com, the new 15-inch Apple notebook will come with a high-resolution 2,560-by-1,600 display. In comparison, Apple's existing 27-inch Thunderbolt display features a 2,560-by-1,440 display.
