Fail to create a Bootable installer for MacBook Pro

General

I need assistance in creating a bootable macOS Sierra installer for my old 2012 MacBook Pro on a Mac tunning macOS Sequoia.

When I was trying to do it in Terminal, I got an error, “sudo: /Applications/Install macOS Sequoia.app/Contents/Resources/createinstallmedia: command not found”

The error "/Applications/Install macOS Sequoia.app/Contents/Resources/createinstallmedia: command not found” tells me that you’re trying to create a macOS Sequoia bootable installer rather than macOS Sierra. What are you truly want to do?

If you want to make a macOS Sierra bootable USB installer on a Mac running macOS Sequoia, you must first ensure your Mac is comaptible with macOS Sierra.

If not, Terminal won’t create the bootable installer. But you can use iBoysoft DiskGeeker for Macto create the bootable installer for macOS Sierra. It can create bootable USB installers for any macOS version even if it’s not compatible with your Mac.
