Instructions: SMC reset on MacBooks with T2 processor

I already told you how the SMC reset works on the Apple Mac in a manual shown. However, the procedure is different if it is a newer model with a T2 chip. Therefore, in this guide you will find the necessary step-by-step instructions for the SMC reset on MacBooks with T2 processor. There is also a quick guide for desktop Macs and an overview of the previous Mac and MacBook models with the corresponding Apple component. So you are well informed. If you still have questions, just leave a comment;)

Here you can find the instructions for an SMC reset on the Apple MacBook with T2 Security Chip. The SMC reset on MacBooks with T2 processor works differently than on previous models of the notebook.

Which Apple computers have a T2 chip?

The T2 Security Chip is a special Apple hardware device which, among other things, ensures more security thanks to the integrated "Secure Enclave" coprocessor. For example, the Touch ID information from MacBooks with Touch Bar is saved there. But there are also video signal and audio controllers as well as SSD controllers and the System Management Controller (SMC) in it. The following Apple Mac computers are equipped with a T2 Security Chip (Source):

Try another procedure before resetting

Apple recommends that you do not perform an SMC reset immediately if you have problems with the notebook, but rather try other steps first. This is the recommended course of action - if it doesn't work, you can continue with the SMC reset guide below:

  1. Turn off your MacBook
  2. Press and hold the on / off switch for 10 seconds
  3. Wait a few seconds and then turn on the MacBook 

SMC reset on Apple MacBook with T2 processor

If you want to perform an SMC reset on an Apple MacBook Pro or Apple MacBook Air with a T2 chip, the procedure differs significantly from the resets on previous laptops from Cupertino. Here are the step-by-step instructions with which you can reset the system management controller on a MacBook from 2018, 2019, 2020 or newer:

  1. Turn off your MacBook Air / MacBook Pro
  2. Press the following keys on the integrated keyboard for 7 seconds:
    Ctrl key / ^ (left)
    Option / Alt / ⌥ (left)
    Shift / ⇧ (right)
  3. After the 7 seconds, also hold down the on / off switch
  4. Also keep all four buttons pressed for 7 seconds
  5. Let go of everything, wait a few seconds and switch the notebook on again
After you have pressed ctrl (left), alt (left) and shift (right) for 7 seconds, you press these buttons for another 7 seconds in combination with the on / off switch.

After you have pressed ctrl (left), alt (left) and shift (right) for 7 seconds, you press these buttons for another 7 seconds in combination with the on / off switch.

SMC reset on desktop computers with T2 Security Chip

As mentioned above, not only the current MacBooks have a T2 chip installed, but also the iMac Pro, the Mac Pro from 2019 and the Mac mini from 2018. That other desktop computers from Apple (possibly coming 2020 models) also have the Security chip installed, that is as good as safe. Therefore, here are the instructions for the mentioned and upcoming models:

  1. Completely switch off Apple Mac / iMac / other desktop variant
  2. Disconnect the power cable from the power supply (pull out of the socket)
  3. Wait at least 15 seconds
  4. Reconnect the power cord to restore power
  5. Wait another 5 seconds and turn on the Mac

What problems does the procedure solve?

There are various reasons for an SMC reset on the Apple Mac, depending on the model and year of manufacture. The procedure can solve a problem with the MagSafe LED as well as problems with the display backlight, a slow computer with no noticeable CPU load, too high a ventilation for no apparent reason, and so on. In short: when the apple computer goes nuts and turns easy switching off and on again nothing brings you, then the steps described above can help you;)

    PRAM reset does not work as it used to with T2 devices. The apple logo appears after 15 seconds.

    Unfortunately, the MBP starts automatically for me as soon as I also hold down the power button. So unfortunately it is not possible to wait a few seconds and then switch it on.
    Try to use the reset to fix a WiFi interruption problem that has been occurring since Big Sur and which leads to regular WiFi connection interruptions.

      Hello Benjamin! Then either Apple changed something or you have an MBP model that behaves differently. Unfortunately, I don't have a solution in both cases. :-(
