iFixit teardown of the MacBook Pro with Apple M4 Pro reveals differences to M3 Pro model
The new M4 MacBook Pro performed well for the most part in our extensive review thanks its new and powerful ARM chip. iFixit has now been able to disassemble the laptop and compare it directly with the M3 Pro predecessor model.
Hardly anything has changed, both internally and externally. The laptop is still opened by loosening a few screws on the underside. Removing the aluminium baseplate reveals the mainboard, in which the position of several circuits has been adjusted, while the Apple M4 Pro is combined with a slightly larger heat sink. The overall design remains fundamentally unchanged.

A positive aspect is that the multi-touch trackpad is still very easy to replace. The six-cell battery is held in place by a total of 14 adhesive strips. These can quickly tear off, making battery replacement a little more difficult than necessary, but it can still be replaced without any major issues. Conveniently, the MacBook Pro's connectors can be replaced individually without the need for a soldering iron, and the Touch ID fingerprint sensor can also be replaced independently of the rest of the keyboard.
To remove the mainboard, numerous different screws have to be loosened, which makes the process relatively time-consuming. SSD and RAM upgrades are still not possible. Repairs are just as time-consuming as on the direct predecessor model, but since Apple now offers original spare parts in its Self Service Repair Store, simple repairs such as replacing the battery, trackpad or USB-C port can be carried out relatively easily.
