Apple is preparing to launch a new family of devices under the "Star" codename, according to a report from 9to5Mac. The secret project apparently involves a line of lightweight Macs running ARM processors, which might combine the best bits of Apple's laptops and mobile devices in one piece of hardware.

Treat this as speculative for now, even though rumors stretching back to last year have claimed Apple wants to get macOS and iOS merged together in some way. That's an idea that Apple boss Tim Cook shot down in an interview last month.
