Problem with hardware ? Reset SMC
I am grateful to the Swedish MacMini support, today when i had some hardware issues. The pointer did not follow the Macic Trackpad 2 move(ment).
The solution was propably to reset the SMC memory by physcally remove the power supply cord at the computer side.
Difficult to find out on support pages, have never even heard about the SMC memory.
Try this at home before calling or visiting Apple Support.
