iFixit today shared an overview of the new MacBook Air and MacBook Pro, giving us a glimpse of what’s under the hood. For the most part, these machines look the same as the older Intel MacBooks inside, but there are a few highlights.
The removal of the fan is the biggest change to the MacBook Air, as the fan has been replaced by an aluminum sprinkler to the left of the logic board.
A thick cold plate above the M1 processor draws heat through conduction to its flatter, cooler end, where it can be safely radiated. Without a fan, this solution may take longer to cool and may be limited sooner, but through previous heat pipes or a steam chamber, the sink also has more mass to saturate with heat. There are no moving parts and nothing to break.
With the exception of a new logic board and cooler, the interior of the MacBook Air is identical to its predecessor, and iFixit says the repair procedures “are likely to remain almost completely unchanged.”
As for the MacBook Pro, it’s so similar to the previous model that iFixit had to check again to make sure the old MacBook Pro wasn’t accidentally purchased.
iFixit is expected to see some consolidation of MacBook parts and design, but the cooling setting is similar to that seen in Intel MacBook models. In fact, the fan is identical to the fan in the 13-inch MacBook Pro 2020, released earlier this year.
While the interiors of the MacBook Air and MacBook Pro are almost identical to Intel’s counterparts, iFixit has looked at the all-new M1 chip, which is the shiny silver bit with the Apple logo. Next to the chip are small silicone rectangles that are integrated Apple memory chips.
iFixit says the integrated memory is “slightly devastating” as it makes repairing the M1 Mac much more difficult. Note that the M1 Mac models do not have a chip designed by Apple T2, as the T2 security feature is integrated exactly into the M1 chip.
iFixit says that while this may seem like a superficial change, it is an expression of “years of intensive work” with “hints of many more to come in the future”. Head to iFixit to read the full breakdown.
