Apple’s long and choppy journey toward releasing a commercially available set of AR glasses just hit another snag. According to Bloomberg’s Mark Gurman, the company has killed a second set of prototype smartglasses designed to connect directly to its Mac computers.
If that sounds like a somewhat limiting design, it wasn’t Apple’s first choice. The company initially wanted the iPhone to power it, Gurman writes, but engineers “ran into problems over how much processing power the handset could provide” and significant issues with battery drain.
