iFixit’s M1 iMac Teardown Reveals an Impressive Little Logic Board – Review Geek



The circuit board of the iMac.

Unlike the M1 MacBook Air and MacBook Pro, the recently released 24-inch M1 iMac has a bold new design with an impressively slim profile and colorful exterior. Now, an iFixit teardown reveals that the iMac̵

7;s makeover isn’t just deep in the skin, although there are still a few hints of the past hidden behind the glass.

Anyone who has had the pleasure of prying open an iMac is familiar with one of its greatest legacies: foaming glue. iFixit found that Apple still uses its classic foaming glue to hold the iMac’s screen in place, making the computer much easier to open than an iPad.

But once you get past the glue, you start to notice some changes. First, the iFixit team found that there are several screws near the edge of the iMac’s screen, making opening the device a bumpy (but not dangerous) ride. Apple has also combined the large bottom bezel (or ‘chin’) of the iMac with the display, so that both components come off simultaneously, allowing for quick disassembly.

Behind this chin is most of the iMac’s hardware, including the circuit board, speakers, and fans. And that’s where the iMac looks very different from its predecessors. The M1 logic board is insane, ridiculously small. This shouldn’t come as much of a surprise as it is essentially the same logic board found in the MacBook Air, MacBook Pro, Mac Mini, and now the iPad Pro. But it’s a huge change compared to previous models.

The circuit board itself also has a few quirks, including a small white button with three LEDs. This button can be for diagnostics, similar to how LEDs were used for diagnostics on older iMac models. Other mysterious shapes appear in iFixit’s iMac X-ray, such as two round objects (perhaps coin-cell batteries) located under the Apple logo.

iFixit left us on a cliffhanger, interrupting the teardown after pulling out the iMac’s logic board. The second part of the iFixit teardown will go online soon, providing an insight into the new Magic Keyboard’s Touch ID sensor (which looks like an old iPhone home button), the speakers, and the weird circles seen in the X-ray. More importantly, the second part of this teardown includes a recoverability score for the new iMac – hopefully it fares better than the 2020 model.
