Apple is working on a few devices unlike anything it had made before, an anonymous leaker said. The ARM MacBook that was featured in a variety of other reports, is one of them. That’s a MacBook using a custom version of Apple’s A-series chips that power the iPhone and iPad. Several people have long theorized that the increasingly more powerful A-series processors could be used inside Macs, and it looks like we’re nearly there. The leaker also said that Apple will launch a brand new iPad Air design, a tablet that will feature an under-screen Touch ID fingerprint sensor, that would be a first for Apple, as the company avoided this particular type of technology on its devices so far.
