There is some concern about Apple’s decision to equip the new MacBook with a single port with which to drive external devices and displays and also pump power into the Mac. That’s because while USB-C is flexible (it can provide USB, DisplayPort, HDMI, VGA and power of up to 100 watts) and reasonably fast (5Gbps, and capable of working in both directions), it isn’t possible to charge your Mac and use an external monitor at the same time without extra investment in a compatible USB-C hub.
The good news is Apple appears to be loosening up to third-party cables. “Most accessories supporting the USB Type-C specifications should work with your new MacBook”, 9to5Mac said. If that’s correct, it means batteries and non-Apple chargers will be compatible with the MacBook.
Small and likely to be widely supported, USB-C may be the future of device interconnects, but potential MacBook buyers will think twice before investing. Many will be put off by the need to buy a hub, new peripherals, or expensive converters (such as one of Apple’s £65 USB-C Multiport adapters) to use their existing kit.
