How to Reset SMC on New iMac, Mac Mini, iMac Pro, & Mac Pro with T2 Chip
Resetting the SMC on new model iMac, iMac Pro, Mac mini, and Mac Pro desktop Macs have a T2 security chip is a different procedure than on earlier models of the same hardware.
SMC, which stands for System Management Controller, handles a variety of hardware functions on the Mac, including power, fan operation, some ports, and much more. Thus resetting the SMC is a common troubleshooting technique when the hardware side of things are not working as expected on a Mac (along with resetting NVRAM / PRAM).
This tutorial will walk through how to reset the SMC on iMac Pro, iMac, Mac mini, and Mac Pro, each with security chips. Unlike Mac laptops, resetting SMC on newer desktops is done mostly with a power cord.
To be clear, this approach includes resetting SMC for iMac from 2020 and newer, all iMac Pro, Mac Pro 2019 and newer, and Mac mini 2018 and newer. Earlier models will use a different method.
