Apple is preparing a new lineup of thinner MacBook laptops running on more powerful chips made by Intel, people with knowledge of the plans say.
The MacBook Pro machines, to be unveiled at Apple's annual developers conference starting on June 11, will also feature high-definition screens like those on the iPhone and iPad, as well as flash memory to cut startup times and extend battery life, said the people, who asked not to be identified because the plans have not been made public.
Apple's Mac sales are growing faster than the personal computer market, benefiting from the popularity of its mobile devices.
Since 2007, when the iPhone was introduced, Apple's Mac sales have more than doubled, reaching US$21.8 billion ($28.4 billion) last year.
As Apple's share has grown, competitors such as Hewlett-Packard, Dell and Samsung Electronics have followed suit in making thinner, aluminium laptops that start up more quickly.
