Make an Intel Mac Boot Directly to Startup Manager
If you have an Intel Mac, you can make it boot directly into the boot disk options startup manager by issuing an nvram terminal command. This could be helpful for advanced users in particular whether they’re troubleshooting, have dual boot situations with multiple versions of macOS, macOS and Windows 10 in Boot Camp, macOS and Linux, for accessing a USB boot drive, a Time Machine restore disk, or myriad other situations where you’d want to boot a Mac directly into the startup manager.
Whether or not this is easier or faster than booting an Intel Mac from an external drive by holding down the Option key on system start and choosing the external volume to boot the Mac from is entirely up to you and your use case. But perhaps the Option/alt key isn’t working for some reason on a Mac, or you want to explore the boot options, or you can’t hold down the key on boot for some reason.
Booting Intel Mac Directly to Startup Disk Manager
As with all command line activity, start by opening the Terminal application, then issue the following command:
sudo nvram manufacturing-enter-picker=true
Because the command is prefixed with sudo you’ll have to enter the admin password.
Then it’s just a matter of restarting the Mac, or turning an off Mac back on again, where you’ll go directly to the boot manager.
If you executed this command at some point and aren’t sure if it’s enabled or not, you can always view and clear the nvram contents via command line too. And of course another way to clear NVRAM is to reset NVRAM / PRAM on an Intel Mac.
Similarly, you can enable Safe Boot Mode for Mac via the command line as well.
Remember this is specific to Intel Mac models, as the Apple Silicon Mac models do not have the same firmware options. If you want to explore more nvram commands and options, check out our archives on the subject.
This tip was found via Twitter from @martinnobel_, where the embedded video below shows what happens after the command has been executed.

I strongly recommend against using this terminal command. I tried it on a 5,1 Mac Pro 2010 with a metal graphics card running Mojave. I was unable to startup with the option key to show the startup manager or any of the startup keys to get anywhere other than the desktop. I thought I’d try this terminal command. My computer would no longer get anywhere. It would power on, but was stuck being forced to get to an area it couldn’t. I had to take it to a specialist. Fortunately, unseating the graphics card, removing the battery from the computer box chassis and pressing the reset—all were able to wake my computer back up. If you can get to those startup areas, you have no need for this command. If you can’t access startup areas with keys, then this command will make it worse.
I used this terminal command as “option” wasn’t bringing my MacPro 5,1 to the startup manager, and now my computer won’t reach a start screen regardless of the keys pressed. It powers on and the screen stays black. How do I cancel this terminal command now that my system’s black? As another has said, my loss. Damn it.
Hi, I’ve tried it, it seems to work but contrary to the option key startup manager, when I boot on my linux system, it actually still boots on MacOS.
Do you have any idea on how to fix this ?
Thanks
Hello
I have the same problem but with Windows,
Did you manage to solve the problem?
I did the command line procedure (sudo nvram manufacturing-enter-picker=true) and when it restarted, it enters the screen that asks for the firmware password, which I don’t have.
Is there a way to reverse the process or I need to go to an apple store?
My model is a MBP 2015 – A1502
Reset the PRAM/NVRAM on the Mac and it will clear out any of the commands
Press and hold the Command, Option, P, and R keys right as you turn the Mac on to reset PRAM (intel and PPC only)
Otherwise you may need to disable the firmware password, which can be done through Recovery mode on the Mac. It must have been enabled at some point.
Dear
I did the PRAM / NVRAM process and nothing has changed.
Please, how can I disable the firmware password via recovery mode on Mac if I can’t access the SSD because I don’t have the firmware password?
Please help me with a “recipe”.
Typically the PRAM reset trick only works with Macs that have removable RAM, and you have to remove the a memory module first and then reset PRAM (and nowadays most Macs don’t have user upgradeable RAM so this is not possible).
How did the firmware password get set? If you set it yourself, maybe you chose the same password as the admin account?
Disabling the firmware password via Recovery Mode works but you’d still need to have enter the firmware password to disable it.
Did you forget the firmware password? If so Apple may have to reset it with proof of purchase. You can read more about the process of dealing with a forgotten firmware password here;

Dear
Why did the mac stay that way, asking for firmware password?
I have not read any other similar report.
So, as you don’t have the solution, the loss is mine.
I learned in the worst way that unknown commands should not be used.
I am genuinely perplexed by this, the firmware password must be enabled specifically through the firmware password tool in Recovery Mode, so it shouldn’t turn itself on. Do you have any additional info?
Dear
I did this procedure to reset the PRAM memory and nothing has changed.
How can I disable the firmware password if I don’t have access?
Please, help me.
Sir/Madame,
Here’s a suggestion for a future article:
• Scanners and scanning software that work on Mac os Big Sur
Since I purchased a new Mac (Mac OS BigSur 11.2.1) I am NOT able to use my scanner (HP ScanJet G3110). When I attempted to install the software that cam with the scanner, the iMac [as expected!] warns me not do do it. I contacted Apple, but the “geniuses” that answered me could not help.
Since then, I looked n line for similar problems with Big Sur and scanner and I found lots of user with the same problem.
Thanks!
“Then it’s just a matter of restarting the Mac, or turning an off Mac back on again, where you’ll go directly to the boot manager”?
Who’s proofreading your copy?
You are apparently, LOL!
What’s the difficulty you are having? Were you unable to use the command to boot your Mac into the startup manager?
