Bootable USB Installers for OS X Mavericks, Yosemite, El Capitan, and Sierra

First, review this introductory article: Create a bootable installer for macOS. Second, see this How To outline for creating a bootable El Capitan installer. Simply replace the Terminal command with the one from the preceding article by copying it into the Terminal window. You will need an 8GB or larger USB flash drive that has been partitioned and formatted for use with OS X.

Drive Partition and Format

1. Open Disk Utility in the Utilities' folder.
2. After Disk Utility loads select the drive (out-dented entry with the mfg.'s ID and size) from the side list.
3. Click on the Erase tab in the Disk Utility toolbar. Name the drive, 'MyVolume'. <---- IMPORTANT!
4. In the drop down panel set the partition scheme to GUID. Set the Format type to Mac OS Extended (Journaled.)
5. Click on the Apply button and wait for the Done button to activate. When it does click on it.
6. Quit Disk Utility.

Create Installer Filepane.

Open the Terminal in the Utilities' folder. Choose the appropriate command line (in red) depending upon what OS X installer you want. Paste that entire command line from below at the Terminal's prompt:

Command for macOS High Sierra:

sudo /Applications/Install macOS High Sierra.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume --applicationpath /Applications/Install macOS High Sierra.app

Command for macOS Sierra:

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

Command for El Capitan:

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

Command for Yosemite:

sudo /Applications/Install OS X Yosemite.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume --applicationpath /Applications/Install OS X Yosemite.app

Command for Mavericks:

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

App To Open Iso File

Press RETURN. You will be asked for your admin password. It will not echo to the Terminal window. Then press RETURN again. Wait for the return of the Terminal prompt signifying the process has completed. It takes quite some time to finish. Be patient.

• This is my first attempt at bash scripting, so please go easy on me. If you have any suggestions, feel free (if not obliged) to share your thoughts.
• If you encounter an error, re-run the script with the extra verbose option '-v 3', copy the whole Terminal output and post it here with as many details as possible (besides the output that is).
• The script is not portable, as it uses some OSX only options. It could be, but it would miss all the .. special effects.
• You'll need 15 GB of free space for that. Most of the time less, but let's be conservative. And if you don't have 15 GB available, the script is the least of your problems.
• The script covers versions 10.7 (Lion), 10.8.x (Mountain Lion), 10.9.x (Mavericks), 10.10.x (Yosemite), 10.11.x (El Capitan), 10.12.x (Sierra), 10.13.x (HighSierra), 10.14.x (Mojave) and 10.15.x (Catalina).
• The script will leave you with an ISO image named '10.#(.#).iso', where # is.. well, you can guess.
• The script does not need administrator access for the 10.7.x to 10.12.x installers. You don't need to be using 'sudo' or being logged in as administrator
• The script does need administrator access for the 10.13.x to 10.15.x installer.

• A network temporary directory will corrupt your ISO. I've been trying to figure out why, to no avail. I'm planning on including a check on whether the temporary directory is on a network volume or not.
• The checksum option is not working as expected. This is the most baffling part in the behavior of the script. You have a script that does the exact same thing, time after time after time. Yet the checksum at the end is like you're generating a random hex number. No clue why it doesn't work.
• Error checking ranges from non existent to not at all. I mean it will definitely fail in the first error encounter, I simply don't do any error redirection/logging.
• NOTES for 10.13.x to 10.15.x: The script will not work if you are a Standard user. You have to be an Administrator in order for the 'sudo' to work, since Standard users cannot 'sudo'. If you are a Standard user, first do a 'su ' before running the script.

• Added support for 10.15.1, 10.15.2.
• Disable Spotlight before unmounting sparse image.
• Fixed an issue when running administrator tasks from within the app.

• Added support for 10.14.6.
• Added support for 10.7.

• Added support for up to 10.15.beta and beyond.
• When using the dry-run simply check for the existence of the installer. Do not check for the available free space or the output/temp directory, since no actual conversion will take place.

• Small fixes for the 3rd party authentication.
• Change the 'if' statements style from 'test' to '[]'.

• There is a GUI app by granada29 that encapsulates the script functionality
  https://www.whatroute.net/installerapp2iso.html
• Incorporated changes by gradana29 for authorization/batch processing.
• Added support for up to 10.14.5.

Power Iso App Download

• Added support for 10.14.2 (18C54).
• Added support for (hopefully) all 10.8.x.
• Added host OSX version information.

• Added support for 10.13.6 (17G65).

Mount Iso App

• Added support for 10.13.5 (17F77).
• Added support for 10.14 beta (18A293u).

• Finally unified the 10.9-10.13 scripts!
  Unfortunately the 10.13 scripts require 'admin' group membership.
• Removed the '--checksum' option. It never worked to begin with.

• When using the dry-run it doesn't check for anything anymore. Not the existence of the installer nor the available free space.
• Trimming of the free space from the sparsebundle is back.

Command for Yosemite:

sudo /Applications/Install OS X Yosemite.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume --applicationpath /Applications/Install OS X Yosemite.app

Command for Mavericks:

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

Sound Siphon makes it easy to capture your Mac's audio. Use it to create virtual input audio devices that send audio from one app to another. Or, record right in the Sound Siphon app.

• Fixed verbosity flags for some cases.

• Fixed a cosmetic error by closing the 'OSX Base System' window.
• Added version and revision information.
