When I use this script for Sierra I become error like this

I don't know why it's not working for you, but the following is the procedure I use and illustrates what you should see. Perhaps you will notice something different than what you have been experiencing.

To create a standalone installer on a USB flash drive or similar removable media, refer to the following instructions: Create a bootable installer for macOS - Apple Support.

Expanded instructions are as follows:

• Format the USB installer as Mac OS Extended (Journaled) and GUID Partition Map.
• Make sure its icon is present on your Desktop. Its name isn't important because createinstallmedia will change it.
• Also, the Install macOS Sierra app must be present in your Mac's Applications folder, otherwise the pathname won't be correct.
• Make the Finder's Applications window small enough so that you can see it, the Terminal window, and the USB drive icon, all at the same time.

Select the following line by dragging your cursor from just prior to the word sudo to past the word volume:

sudo /Applications/Install\ macOS\ Sierra.app/Contents/Resources/createinstallmedia --volume

Then, Edit > Copy.

Go to the Terminal window, paste that line into the Terminal window, and type a space character. Stop right there; do not press Return.

Drag the USB flash drive icon from your Desktop to the Terminal window, and stop again.

Then, type (or copy/paste) the following into Terminal:

--applicationpath

... followed by another space character.

Then, drag the Install macOS Sierra icon from your Applications folder into the Terminal window.

Finally, you can press Return.

This is an example of what should happen. The name of the USB drive is "untitled" in the following:

MacBookAir2:/ john$ sudo /Applications/Install\ macOS\ Sierra.app/Contents/Resources/createinstallmedia --volume /Volumes/untitled --applicationpath /Applications/Install\ macOS\ Sierra.app

Password: (type your Admin password - it will not be echoed, not even with •••• characters. Then press Return)

Ready to start.

To continue we need to erase the disk at /Volumes/untitled.

If you wish to continue type (Y) then press return: Y

Erasing Disk: 0%... 10%... 20%... 30%...100%...

Copying installer files to disk...

Copy complete.

Making disk bootable...

Copying boot files...

Copy complete.

Done.

MacBookAir2:/john$

When it's finished the name of your USB installer will be Install macOS Sierra and it will be selectable as a bootable device in Startup Manager: How to choose a startup disk on your Mac - Apple Support.

That will result if the Install macOS Sierra app is not in that Mac's Applications folder.

As I wrote,

Also, the Install macOS Sierra app must be present in your Mac's Applications folder, otherwise the pathname won't be correct.

( My application is really Sierra.app and not "Install macOS Sierra.app")

The name of the installer app provided by the Mac App Store is Install macOS Sierra as shown in the screenshot below:

If you change the name of the installer provided by the Mac App Store then it is not possible for me to predict what will occur.

If the name provided by the Mac App Store is different for your location, then you would need to amend the instructions to reflect that name.

Well in version12.2.06 of Sierra install application, that file is definitely there at that location.

What version of the installer do you have? Do a Command+i to get a "Get Info" window, and what does it show for "Version" number?

When I try the command "/Applications/Install macOS Sierra.app/Contents/Resourses/createinstallmedia --help" I get the suggested form of the command as

Usage: createinstallmedia --volume <path to volume to convert> --applicationpath <path to Install macOS Sierra.app> [--force]

Arguments--volume, A path to a volume that can be unmounted and erased to create the install media.

--applicationpath, A path to copy of the OS installer application to create the bootable media from.

--nointeraction, Erase the disk pointed to by volume without prompting for confirmation.

Example: createinstallmedia --volume /Volumes/Untitled --applicationpath "/Applications/Install macOS Sierra.app"

This tool must be run as root.

So this implies to me that you should try the command:

sudo /Applications/Install\ macOS\ Sierra.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume\ Titel/ --applicationpath /Applications/install\ macOS\ Sierra.app —nointeraction

So it appears to me that you had two mistakes - one was a space between the "--" and "nointeraction" and the other was the path for the install app itself not the path for the "createinstallmedia" command.

This is just a guess, as I don't want to run this command on my system at the moment.

Good luck...

sudo /Applications/Install\ macOS\ Sierra.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume\ Titel/ --applicationpath /Applications/install\ macOS\ Sierra.app --nointeraction

Should be the command - somehow the -- got changed to a -

Sorry about that.

Good luck...

You did not enter the command correctly - the command is continued on the next line in John Galt example.

It does not appear that you have the sierra install app though. What do you have for these commands in Terminal (there are 3 separate commands - enter one at a time by simply copying/pasting the following):

ls -la /Applications/Install\ macOS\ Sierra.app

ls -la /Applications/Install\ macOS\ Sierra.app/Contents

ls -la /Applications/Install\ macOS\ Sierra.app/Contents/Resources

Good luck...

I understand there may be challenges in language translation, but please re-read and follow my instructions again with care. The initial Terminal line is quite long and requires four separate steps interspersed with space characters. What you performed was incomplete.

Confirm that you have the "Install macOS Sierra" app in your Applications folder.
