SMC Reset MacBook Pro Air iMac Mini

Reset your Mac's SMC

How do I reset the SMC?

Resetting the SMC works slightly differently depending on the model.

Here I describe how this works on different models!

Mac Mini, Mac Pro and iMac:

For the devices, it is enough to simply disconnect the device from the mains by pulling out the power cable, i.e. unplugging it.

Unplug the power cable and wait 15 seconds. Then plug the power cable back in and wait again for 5 seconds. Now the device can be switched on and the SMC has been reset.

Macbook and MacBook Pro with removable battery:

1. Turn off the Mac.

2. Take out the battery.

3. Press and hold the power button for 5 seconds.

4. Put the battery back in.

5. Press the power button to turn on the Mac.
