Bloomberg's sources claim that the new laptop will look similar to the current MacBook Air, but will include thinner bezels around the screen. The display, which will remain about 13-inches, will be a higher-resolution "Retina" version that Apple uses on other products, Bloomberg said. The new MacBook Air will be geared toward consumers looking for a cheaper Apple computer, but also schools that often buy laptops in bulk.

Apple is also planning the first upgrade to the Mac mini in about four years.

It's a Mac desktop that doesn't include a screen, keyboard, or mouse in the box and costs $500. For this year's model, Apple is focusing primarily on these pro users, and new storage and processor options are likely to make it more expensive than previous versions.

Apple declined to comment.

In addition to the new Mac models, Apple is preparing to launch macOS Mojave, a new version of its Mac operating system. The company is also planning a new version of the Mac Pro, the company's most high-end Mac, for next year.
