Like it is with all Apple products, iFixit has gone ahead and performed a teardown of the M1 iMac, showing how a small logic board featuring the M1 chip can be placed inside the machine of this size. This partial disassembly also shows a different cooling system if you opt for the higher-tier configurations.

According to iFixit, Apple has once again used adhesive to seal the M1 iMac. However, the teardown aficionados point out that the glue used here is not as difficult to work with as the one that the company uses on other products, such as the iPad. We do not know if any M1 iPad Pro model has reached iFixit for a future teardown, but we will continue to update our readers.
