Apple’s design team went to extreme lengths when redesigning the new MacBook to be more portable than ever. The most drastic move was to toss out the fan and extra ports for a super-tiny logic board.
The new MacBook logic board is two-thirds smaller than any board Apple’s designed before. It’s the highest-density Mac logic board yet, but really, it’s more like a super-iPhone or iPad logic board. Put side by side with the iPhone 6 logic board, the new MacBook logic board is barely twice its size.
