I thought the new updated multimedia USB-C adapter supported that?No point 4K screen on a 10-13” device. Probably not even on a MBP. If your editing 4K footage you wouldn’t be watching just the footage on the laptop screen anyway - you’d drive an external monitor.
I hope (and think it’s more likely) that Apple updates the usb-c out to support driving a 4K display at 4K - perhaps even extended ‘desktop’ for things like video editing. Seems a ‘pro’ thing to support.
