Works on all Macs with an Intel Processor (MacBook, MacBook Air, MacBook Pro, Mac Mini, iMac, iMac Pro, etc)
support.apple....
According to Apple:
NVRAM (nonvolatile random-access memory) is a small amount of memory that your Mac uses to store certain settings and access them quickly. PRAM (Parameter RAM) stores similar information, and the steps for resetting NVRAM and PRAM are the same.
Settings that can be stored in NVRAM include sound volume, display resolution, startup-disk selection, time zone, and recent kernel panic information. The settings stored in NVRAM depend on your Mac and the devices that you're using with your Mac.
If you experience issues related to these settings or others, resetting NVRAM might help. For example, if your Mac starts up from a disk other than the one selected in Startup Disk preferences, or a question mark icon briefly appears before your Mac starts up, you might need to reset NVRAM.
According to Apple:
How to reset PRAM/ NVRAM
Shut down your Mac, then turn it on and immediately press and hold these four keys together: Option, Command, P, and R. You can release the keys after about 20 seconds, during which your Mac might appear to restart.
On Mac computers that play a startup sound, you can release the keys after the second startup sound.
On Mac computers that have the Apple T2 Security Chip, you can release the keys after the Apple logo appears and disappears for the second time.
When your Mac finishes starting up, you might want to open System Preferences and adjust any settings that were reset, such as sound volume, display resolution, startup disk selection, or time zone.

If you're using a desktop Mac instead of a notebook, and settings such as sound volume or time zone are reset every time you shut down and unplug your Mac, you might need to replace the battery inside your Mac. This small battery is on your computer's logic board, and it helps NVRAM retain settings when your Mac is unplugged. You can take your Mac to an Apple service provider to replace the battery.
If you experience issues with sleep, wake, power, charging your Mac notebook battery, or other power-related symptoms, you might need to reset the SMC (System Management Controller).
If your Mac is using a firmware password, this key combination does nothing or causes your Mac to start up from macOS Recovery. To reset NVRAM, first turn off the firmware password.

Well, you shouldn’t really try to unlock it yourself and trying something which you don’t know as it might do some extra bit damage. You can just take it to any Apple Store, or Apple Reseller or any authenticated Tech Guy Like *MOE* where they sell MacBook They’ll just log onto iTunes on their Mac and your problem should be resolved in 10-15 minutes. They effort required is very less, it’s just about knowing the thing that you’re doing. *MOE* charges are less. By the way, technically they shouldn’t ask for anything as it isn’t a laborious work at all so if you argue enough with them, they might not charge you. But also, they will ask you for the Apple ID and Password. So, it would be better to change the password after the work has been done just for security purposes.

Your operating system is not working and or not installed. So you must go into recovery mode to fix it and reinstall macOS. Sorry.

Everyone get out of here with your Moe spam. 😂😂😂 This doesn’t ‘repair’ anything on the computer including iCloud activation lock. It reverts the computer back to some default settings during the restart that allows it to perform normally if it’s been acting weird.

Hi, my Mac won't restart or chime twice for many reasons (now anyway my HD is empty, no mac os on my mac). Whatever; when I try to reset the nvram with those commands I can see down the screen left corner "reason nvram" flashing as long as I ^press the commands. How do you interpret "reason nvram" in English on a Macbook Pro ?
