The arrival of Apple’s new M2-equipped 13-inch MacBook Professional touchdown in shops formally marks the arrival of the second technology of Apple Silicon. It’s additionally the primary Apple Silicon Mac to be re-released with a more recent chip.
For the reason that 2020 M1 MacBook Professional and the 2022 M2 MacBook Professional are so clearly related in design and specs, this has led many to ask the apparent query. Can an older 2020 MacBook Professional with an M1 chip merely have the M2 chip swapped in?
To be clear, this query is extra of an mental curiosity than anything. Apple will not be Intel; it doesn’t — and nearly definitely by no means will — promote the M2 chip in its retail shops. Because of this, proper now, the one technique to get your arms on an M2 chip is to purchase Apple’s latest 13-inch MacBook Professional. When you’ve accomplished that, there’s not a lot level in placing the chip into the 2020 mannequin.
Nonetheless, Apple fanatic Luke Miani determined to attempt to reply this query on his YouTube channel only for kicks.
At the moment’s video is dumb, and pointless, and admittedly serves no actual function. However I’m gonna do it anyway, as a result of lots of you guys have requested. Luke Miani
A Story of Two MacBooks
Leaving apart the futility of such an enterprise, Miani’s mission was nonetheless fascinating in revealing how extremely related each MacBook Professional fashions are.
We already know that Apple’s latest M2 MacBook Professional is visually indistinguishable from its predecessor, nevertheless it seems that it’s nearly solely unchanged on the within as nicely.
After taking the covers off each the 2020 M1 MacBook Professional and 2022 M2 MacBook Professional and inserting them facet by facet, it was apparent they had been just about equivalent.
The one change Miani found at first look was the flash reminiscence (SSD) storage. The older MacBook Professional makes use of a pair of 128GB chips, whereas the most recent mannequin has a single 256GB chip with house for a further one. However, the chips are soldered on, so that is extra about cost-efficiency in manufacturing, not upgradeability for finish customers.
Miani then took the logic board out of the M1 MacBook Professional, noting how clear and skinny the board was, adopted up by doing the identical with the M2 logic board. He additionally famous that many tiny connectors and hidden screws should be fastidiously indifferent to perform this. Unsurprisingly, Apple doesn’t intend for mere mortals to try to disassemble its newest MacBooks.
However, the logic board from the M2 MacBook Professional bodily suits into the older MacBook with none issues. All of the mounting screw holes and connectors lined up the identical.
After putting in the M2 logic board into the older M1 MacBook Professional and hooking the whole lot accurately, the consequence was: nothing. The older MacBook Professional merely wouldn’t energy on.
Miani then proceeded to strive swapping over the Contact ID sensor from the newer M2 MacBook Professional after which checked, rechecked, and rechecked the whole lot once more. Nevertheless, the M1 MacBook Professional with the newly-installed M2 logic board merely refused to get up in any respect. Even making an attempt to place it into “DFU mode” with Apple Configurator wasn’t profitable.
I truthfully don’t know what to say at this level. I’ve double, triple, and quadruple-checked each single connection on right here. I’ve swapped over the Contact ID button from the M2, so it’s the right, matching one. I even tried utilizing Apple Configurator to attempt to get this factor in DFU mode and restore it. There’s completely nothing. Luke Miani
So, Miani proceeded to change the whole lot again to the way it was and see if the MacBooks labored of their unique {hardware} configurations. As soon as he did that, he found that each booted up similar to they did earlier than he started the experiment.
There are not any obvious explanations for why the older MacBook Professional did not boot with the M2 logic board. Miani pointed to at least one chance highlighted in a Tweet by Hector Martin, a developer engaged on porting Linux to Apple Silicon, that talked about a brand new keyboard and trackpad interface. This means the highest case might have modified within the newest MacBook Professional. Nevertheless, Miani hasn’t explored that any additional.
This can be an instructional query proper now, nevertheless it might matter sometime. Apple’s self-service restore program solely covers iPhones proper now, however it can ultimately develop to Macs, and when it does, clients might be able to order new logic boards. Whereas the price of elements would possible make a DIY M2 improve cost-prohibitive, as Miani explains, an M1 MacBook Professional proprietor with a lifeless logic board would possibly latch onto the concept of ordering an M2 logic board as a substitute. Nevertheless, that sadly gained’t work, as Miami’s experiment demonstrated.
