Mac Keyboard and Trackpads. Updated 2023
The keyboard and trackpad both connect to the logic board, but not to each other. If you experience an issue with your keyboard and trackpad at the same time, you most likely have a software-related issue
Here are a number of reasons that could be the cause of the Trackpad and Keyboard not responding.
1. It is possible that a recent change in software can cause the problem.
2. The trackpad could be dirty and this can prevent it from reading your movements.
3. When both the Keyboard and Trackpad fail at the same time, the problem may be with just the Trackpad or the Trackpad Flex Cable.
In the USB-C model, Apple Mac the Trackpad or Trackpad Cable is not considered to be a separate part however it is seen as part of the Top Case Assembly, which includes the Keyboard as well.
4. If it is only the Keyboard that is not working it could be that the Keyboard is faulty and needs to be replaced.
Try these steps to resolve the Trackpad and Keyboard issue:
1. Restart your Mac by turning it off and on again sorting out a possible software issue.
2. Shut down your Mac completely after it restarts and if this does not work shut down the Mac and plug in the power supply.
3. Check the trackpad settings in System Preferences to ensure that everything is set up as it should be.
Issues caused by the Trackpad Cable have been seen in both the Keyboard and Trackpad failure.
