According to Apple, the new computers come with an updated Intel Core M processors, improved graphics performance, faster RAM for multitasking, faster flash storage and an extra hour of battery. It keeps the same design, making it still the thinnest and lightest of Apple's laptops.
Despite these updates, nobody would really notice a significant difference in the performances of this year’s and last year’s 12-inch MacBook. All of the updates are pretty minor; everyone would be hard pressed to tell any difference at all if they used these laptops side by side.
The biggest thing that anybody will notice from these new MacBooks, however, will be the additional hour of battery life and the new color. Last year’s MacBook offered about 9-10 hours of battery life; getting an extra 10 percent on top of that is a nice bonus for mobile users.
Also, Apple gave it the rose gold, or pink, finish that has been seen in Apple's iPhones, iPads and Apple Watches before. The computer could already be bought in a normal gold as well as space grey or silver finish – but now Apple has unified the color options across most of its flagship units.
"MacBook is the thinnest and lightest Mac we have ever made and it's our vision for the future of the notebook," said Philip Schiller, Apple’s marketing head, in a statement. "Customers are going to love this update to MacBook, with the latest processors, faster graphics, faster flash storage, longer battery life and a beautiful rose gold finish."
Some had thought that Apple could update the laptops at its Worldwide Developers Conference (WWDC), in June, but it announced the new computer just hours after the date of that event was confirmed. Apple might still update other laptops in its line at the event, however.
