Apple has unveiled its next-generation of laptops at the Worldwide Developers' Conference (WWDC) 2012 in San Francisco.
The new MacBook Pro has a 'Retina' display, featuring a screen with four times as many pixels as the previous generation.
Applications will need to be re-written to get the most out of the new display, Apple said - adding it had already updated its own OS and had worked with some developers to get their Apps ready.
The laptop is the thinnest pro laptop Apple has ever made, at just 0.71 inches.
"A true breakthrough in engineering," said Apple's Phil Schiller.
It comes with a quad-core i5 or i7 processor, with seven hours of battery life and up to 768gb of flash storage.
The new MacBook has an HDMI output, for the first time on a Mac laptop, and two Thunderbolt ports.
Apple also updated its MacBook Air and MacBook pro lines with new processors and USB 3.0 ports.
The new Retina Display laptops will start for UK customers at £1,799. The 2.6GHz 512Gb will cost £2,299. The updated MacBooks will cost £849 for the base level Air, £999 for the 13in Pro i5 and £1,499 for the 15in Pro.
Apple CEO Tim Cook showcased the new release at the Moscone Center during his annual keynote at the event.
