The lack of a fan is the biggest change in *MacBook Air*. The fan has been replaced by an aluminum plate on the left side of the logic board.
Except for the new logic board and heat sink, the interior of the MacBook Air is the same as the previous product. iFixit said the repair method "may remain almost unchanged."
As for the MacBook Pro, it is very similar to the previous model. iFixit believes that Apple will integrate some MacBook parts and designs, and its heat dissipation settings are similar to Intel’s MacBook models. In fact, the fan is the same as the fan in the 2020 13-inch MacBook Pro released earlier this year.
Although the internal structure of MacBook Air and MacBook Pro is almost the same as that of similar Intel products, they do use a brand-new M1 chip, which is shiny silver with Apple logo. Next to the chip, the small chip is Apple’s integrated memory chip.
iFixit stated that integrated storage is "destructive" because it makes repairing the M1 Mac more difficult. In addition, there is no T2 chip designed by Apple in the M1 Mac model, because the T2 security function has been directly integrated into the M1 chip.
