In the review of the new 13-inch MacBook Pro M2, I wrote, “It’s no exaggeration to say that Apple simply retired the M1 and replaced it with the M2, and lo and behold, a new laptop. . Well it turns out it might be is a bit exaggerated.
YouTuber Luke Miani basically put that statement to the test. He carefully removed the logic boards from the old and new 13-inch MacBook Pro, then installed the M2 board into the M1’s case. And when he pressed the power button on the laptop, nothing happened.
Miani’s video has shots of the logic boards side by side, and they look identical except for the NAND flash memory, where the M2 board has a 256GB chip and the M1 board has a pair of 128GB chips The cards even have the same zip connectors, so placing the M2 card into the MacBook Pro M1 was a relatively simple task.
But no matter what Miani did, the laptop wouldn’t turn on. He tried swapping the Touch ID buttons, running the Apple Configurator, and confirming that all the connectors are in place, all to no avail. When he put the motherboards back in their original cases, they worked.
The commenters on Miani’s video have some ideas as to why the switch didn’t work. Some believe the M2 has different power requirements. A reviewer said that the M2 has a different way of connecting the keyboard and trackpad which would prevent the power button from working. Others have suggested that there is a security lock not being triggered, different pin configurations, or that the board is not recognizing components such as the battery.
Whatever the reason, Apple has done more than just replace the M1 with the M2, no matter how bad that seems. So if you want the fastest chip, you’ll have to buy a new Mac.
