iFixit was picked up by the new M2 Mac to do a traditional device teardown.

iFixit doesn't have a lot to say about the M2 MacBook Pro because it's identical to the prior- generation MacBook Pro. There are updates focused under the hood of the device.

iFixit found almost every component to be the same and couldn't identify any changes outside of it. The rest of the interior is the same as before, even though some of the chips have been updated.

The M1 and M2 boards were pulled out of the M1 MacBook Pro case. The M2 chip wouldn't work in the M1 because of the component swap. When the M1 and M2 chips are replaced, the Touch ID sensor fails to function.

iFixit claims that Apple is trying to block repairs and replacements through software locks as the M2 MacBook Pro components fit inside the M1 MacBook Pro.

Previous arguments for the lack of upgradeability between generations have centered around size considerations within the chassis or cost considerations or manufacturing limitations. So how do we explain this?

The design of the SSD has led to slower benchmark performance on the M2 MacBook Pro than on the M1 MacBook Pro. The M2 MacBook Pro and the M1 MacBook Pro both use a single chip with a maximum of 128 gigabytes of storage. The system can read and write up to twice as fast because of the two chip system. It's not clear why Apple made this change, but iFixit thinks it's because of component shortages.

iFixit said that Apple missed an opportunity to introduce its first upgradeable device in a long time, and that the company also missed the chance to set the tone for repairability and eco-friendly design.
