Resetting the SMC of your Mac
How do I reset the SMC?
Resetting the SMC works slightly differently depending on the model.
Here's how it works on different models!
Mac Mini, Mac Pro, and iMac:
For these devices, it's enough to simply disconnect the device from the power by unplugging the power cord.
Unplug the power cord and wait for 15 seconds. Then plug the power cord back in and wait another 5 seconds. Now you can turn on the device and the SMC will have been reset.
