I just don’t buy that rumour - why would they cripple this brand new laptop with one of the failings of the previous Macbook, by only having a single port? I love the 12” Macbook and have owned a few, but if anybody says that having a single port on it wasn’t a complete PITA then they’re lying. Even the iPad Pro with Magic Keyboard gives you one port for power and one for peripherals.
Its never been so easy to pass yourself off as someone “in the know” with subjects like Apple leaks. There’s so much interest out there that anybody can do it and get reasonable traction on social media, but we all know there’s very few people out there who have genuine, reliable inside information.
I still think that the new Apple Silicon Macs should be aiming for hardware/feature parity with the iPad Pro as a starting position (promotion screen, FaceID, good quality webcam).
