This is why you should install macOS upgrades and updates while your Mac is connected to the internet: during installation, the macOS installer will check whether it needs any EFI or similar updates, and may download and install them then.

These include the EFI firmware, the SMC, NVRAM and (in certain models) the T2 chip.ĮFI firmware is the fundamental software that gets your Mac going. But in order to boot it up sufficiently to be able to load that up, and to enable certain hardware features controlling the cooling fans, battery charging, etc., every Mac has firmware and persistent storage for some key settings.

Seem it works and it does what is expected, but I don’t know if it is really same like ‘keyboard gymnastic’ (I like this expression) described by you in article above and I have no idea how it is related to iMac Pro and 2018 models with T2, how does it work if firmware password is set, etc. for things above in this article, what I sometimes do, I use Terminal commands from Recovery mode: Unfortunately sometimes even Apple’s own Support have no clue what’s going on when you contact them, because even for them there is no relevant source of information available. I still hope it will change, and we would be able to read again and understand exactly what’s going on in our systems.

Oh yeah, that’s true and sad, Apple documentation (including man pages) these days is incomplete, outdated, and for many things simply missing. It should be reinstituted as a matter of urgency. It used to provide lists of recently added and updated support notes, but discontinued this practice some years ago. It is also unacceptable that Apple has no means of alerting its customers to such significant changes in its documentation. It is absurd there are now six quite different procedures for resetting the SMC, some involving keyboard gymnastics which many Mac users will at least find difficult. It is a great pity – and a pain for users – that this doesn’t now extend to the design of routine maintenance procedures. I have updated my article on resetting SMC and NVRAM to reflect these changes.Īpple takes pride in its superlative design. Release those keys and the Power button, and wait a few seconds before pressing the Power button to start it up again.Then keep holding those keys while you also press and hold the Power button for another 7 seconds. Once it is shut down, press and hold the right Shift key, the left Option key, and the left Control key for 7 seconds.

Reconnect its mains power lead, and wait for 5 seconds.

Disconnect its mains power lead for 15 seconds.

In the event that that procedure fails to reset the SMC, Apple now recommends one of two procedures to be used as fallbacks. It is now becoming clear that this doesn’t always work. (Apple has changed the period of time for which to hold the Power button from 8 to 10 seconds.)

after releasing the Power button, wait a few seconds, then press the Power button to start the Mac up.

once shut down, press and hold its Power button for 10 seconds.

In case you have already forgotten, these are: At least when there you can turn the password off, I suppose.Īpple had previously detailed standard procedures for resetting the SMC of Macs with T2 chips, currently iMac Pro and MacBook Pro 2018 models. If you don’t turn a firmware password off and then try to reset the NVRAM, that reset will fail, and your Mac will probably enter Recovery mode instead. You can then start it up with the Command, Option, P and R keys held ready to reset the NVRAM. In that, turn the firmware password off, and shut your Mac down. To do that, restart in Recovery mode, and in the Utilities menu, select either the Firmware Password Utility or Startup Security Utility. Apple has recently updated its support information on two important topics, resetting the SMC and the NVRAM.Īpple has recently pointed out that, if your Mac has a firmware password set, you must turn that off before attempting to reset the NVRAM.
