Question: M1 SMC reset

I recently received a MacBook Pro which I am doing a little troubleshooting about the length of battery life with and wanted to reset the SMC. Is the procedure the same as for MacBook Pro's with the T2 chip? (left) ctrl + opt + (right) shift - 7 seconds, then add pwr button 7 seconds and release. Also, I was told that there is no NVRAM on these Macs. Is that true?


Thanks in advance.

MacBook Pro 13″, macOS 11.0

I have the new M1 Mac mini and it’s giving me all kinds of problems. I just had a tech-support call and she told me to reset the SMC. I’m not 100% sure the steps (she only said them once and I didn’t immediately write them down) but I think she said shut down the computer then hold control option shift for seven seconds. I did this, and nothing seemed to happen and the computer did not start up as she said it would, so I assumed nothing happened, but she said it doesn’t always start up this way. However, when I did start the computer I was asked to log back into my Adobe creative cloud, so that makes me think something did actually happen. It did not resolve the issue of the computer not recognizing both of my monitors. I’m extremely frustrated with the Mac mini and I’m not sure if I have a lemon or not. I will be speaking to Apple support tomorrow again.

I called apple support recently asking how I could reset the nvram on the m1 MacBooks and they told me to press option-command-p-r but I told them that that did not work and I said it might be because I am using a m1 MacBook and they then realise they had made a mistake and thought I was using intel MacBooks and after that, they simply told me that there is no way to reset the nvram on the m1 MacBooks/desktops.

Hello jeffmr4

Thank you for contacting Apple Community

You can’t reset the SMC, because the M1 Mac doesn’t have a System

Management Controller. You can’t manually reset the NVRAM / PRAM because

your Mac does this automatically, if needed, during every startup.

Best regards,

John

There is no combination of buttons to reset the M1 MacBook. Turn it off, close the lid for 30 seconds then reopen it. That is the equivalent to resetting the SMC

Incorrect. See the post above yours. Not to mention M1 Mac mini's have no lid.

No—


it is not the same there is no SMC or NVRAM it is all on the M1 SoC.

I’ve modified some NVRAM settings in my MacBook Air M1, after a reboot, the OS didn’t boot, so the NVRAM settings won’t reset after a reboot, not even after powering it off and keep the lid close for a while, I had to modify again the NVRAM settings using Terminal in the startup options boot mode to get back the OS bootable again.


Edit: First time posting here, didn’t want to reply to you but to the general post, sorry!!
