createinstallmedia: command not found

Hi,

My apologies for not specifying that command. Type this in a terminal window:

sudo chmod u+x /Applications/Install\ macOS\ Sierra.app/Contents/Resources/createinstallmedia

Hi!

I had this exact same problem, I kept getting "command not found" no matter what I did. I finally got it to work by changing the permissions of the createinstallmedia program to u+x, i.e. owner executable. Hope this helps someone.

Hi!

How did you change "permissions of the createinstallmedia program to u+x" ??

Try this one Man. 100% worked.

sudo /Applications/Install\ OS\ X\ El\ Capitan.app/Contents/Resources/createinstallmedia --volume /Volumes/Capitan --applicationpath /Applications/Install\ OS\ X\ El\ Capitan.app

Enjoy 🙂

COPY/PASTE the command, not type it.

/Applications/Install\ OS\ X\ El\ Capitan.app/Contents/Resources/createinstallmedia

You do that by clicking three times on the line to select the whole line, then "copy", then paste it in Terminal.

This command is correctly mentioned by Barney in his post above.

Not sure what's happening.

Open your Applications folder. Right click on your Install OS X El Capitan.app file, choose Show Package Contents and expand the folders for Contents, Resources and see if the createinstallmedia file is in Resources.

Hi, I'm running macOS Sierra (macbook pro) and want to create a usb boot with Mavericks.

Mavericks.app is under the application folder.

Sudo / Applications / Install \ OS \ X \ Mavericks.app/Contents/Resources/createinstallmedia --volume / Volumes / MyVolume --applicationpath / Applications / Install \ OS \ X \ Mavericks.app

But gets error "command not found"

Your command string is not formed correctly for El Capitan.

Try copying the command from here instead of trying to type it out: Create a bootable installer for macOS - Apple Support

You have El\Captian in your sudo command instead of El\ Capitan with a space after the \. Just fix those 2 misspellings/spacing and try again. Make sure El is E L not E I(eye).

Yours:

sudo /Applications/Install\ OS\ X\ EI\Captian.app/Contents/Resources/createinstallmedia --volume /Volumes/Captian --applicationpath /Applications/Install\ OS\ X\ EI\Captian.app --nointeraction

Should be:

sudo /Applications/Install\ OS\ X\ El\ Capitan.app/Contents/Resources/createinstallmedia --volume /Volumes/Capitan --applicationpath /Applications/Install\ OS\ X\ El\ Capitan.app --nointeraction

For Sierra it should be (make sure your external volume name is Sierra for the following to work):

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

Are you trying to do this locally or remotely?

Your screenshot of your Terminal command looks like you're using ssh remotely. If that's the case, make sure the Install OS X El Capitan.app file is in the remote Mac's /Applications folder and spelled correctly. I have always created these locally.

Sudo / Applications / Install \ OS \ X \ Mavericks.app/Contents/Resources/createinstallmedia --volume / Volumes / MyVolume --applicationpath / Applications / Install \ OS \ X \ Mavericks.app

If that is the exact command you used, then it will fail as you have put spaces in front of every escape character (\)

There should be no space before the escape character ( \ )

If you copy and paste from the link I posted above, it will be formatted correctly.

@Midori2. Try this one. 100% worked.

sudo /Applications/Install\ OS\ X\ El\ Capitan.app/Contents/Resources/createinstallmedia --volume /Volumes/Capitan --applicationpath /Applications/Install\ OS\ X\ El\ Capitan.app

(your USB must name:Capitan)

Peach,
