Apple plans to announce an update to its laptop lineup at an annual conference for app developers in early June, a move that could help offset new competition from Microsoft as well as declining iPad sales.

Apple is planning three new laptops, according to Bloomberg. The MacBook Pro will reportedly get a faster Kaby Lake processor from Intel. Apple is also working on a new version of the 12-inch MacBook with a faster Intel chip. The company has also considered updating the aging 13-inch MacBook Air with a new processor.

Apple declined to comment.

The Mac lineup generates just 11 percent of the Cupertino, California-based company's $216 billion in annual sales, with the iPhone accounting for almost two-thirds of the total.

The MacBook refresh comes as Microsoft debuted the Surface Laptop, which boots up in seconds, has a touch screen and runs on a more stable version of Windows.

While unclear if it's ready for this generation, Apple has been also working on a new in-house chip for a future MacBook Pro model that manages the computer's low-power mode.

Apple last updated the 12-inch MacBook in the spring of 2016 with a rose gold color option, while the MacBook Air has not received a speed boost since 2015.
In addition to the new Macs this year, Apple will likely announce an upgraded version of the macOS operating system.
