Good evening Apple Support Community,
I need direction(s)/advise for procuring the command line code to create a bootable MacOS Sierra USB via Terminal. I did try modifying the MacOS High Sierra command line in Text Edit.
No luck........
Thank you kindly,
Leonard1956
Not that it matters ......currently my working device is a MacPro 2012.

Open Terminal (Applications/ Utilities) now copy and paste this command into the Terminal window,
sudo plutil -replace CFBundleShortVersionString -string "12.6.03" /Applications/Install\ macOS\ Sierra.app/Contents/Info.plist
press return
enter your password
press return
Now paste in the createinstallmedia command for Sierra where MyVolume can be replaced with the name of your USB stick
If your USB name has more than one word separated by spaces you would need to type it in as
/The\ USB\ Name
sudo /Applications/Install\ macOS\ Sierra.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume --applicationpath /Applications/Install\ macOS\ Sierra.app
press return
follow the prompts
everytime I run the command to create the bootable USB, I get the error: /Volumes/MyVolume is not a valid mount point. When I format the USB drive, using the Apple instructions, I chose 'MyVolume' as the name of the volume, so the name is correct. Why does this simple task need to be so freaking complicated. I've wasted hours and hours an hours already, trying to follow Apple's instructions to re-install the OS on my 2014 Mini after disk failure. I installed yosemite, but from that, I can't update to Monterey. So I am trying to install Sierra, which apparently can then be updated to Monterey, but that fails too. Apple, REALLY!!!! do you really have to make life **** for your customers!!!!
