Sep 04, 2015  Mac OS X 10.9; This is a self made 10.9 mavericks full dmg. It only has osx 10.9 vanilla image. This can be use to make USB installer that will work on.

These advanced steps are primarily for system administrators and others who are familiar with the command line. You don't need a bootable installer to upgrade macOS or reinstall macOS, but it can be useful when you want to install on multiple computers without downloading the installer each time.

Download macOS

Find the appropriate download link in the upgrade instructions for each macOS version:

  • macOS Catalina, macOS Mojave, and macOS High Sierra download directly to your Applications folder as an app named Install macOS Catalina, Install macOS Mojave, or Install macOS High Sierra. If the installer opens after downloading, quit it without continuing installation.
    To get the required installer, download from a Mac that is using macOS Sierra 10.12.5 or later, or El Capitan 10.11.6. Enterprise administrators, please download from Apple, not a locally hosted software-update server.
  • macOS Sierra downloads as a disk image that contains a file named InstallOS.pkg. Open this file and follow the onscreen instructions. It installs an app named Install macOS Sierra into your Applications folder.
  • OS X El Capitan downloads as a disk image that contains a file named InstallMacOSX.pkg. Open this file and follow the onscreen instructions. It installs an app named Install OS X El Capitan into your Applications folder.

Use the 'createinstallmedia' command in Terminal

  1. Connect the USB flash drive or other volume that you're using for the bootable installer. Make sure that it has at least 12GB of available storage and is formatted as Mac OS Extended.
  2. Open Terminal, which is in the Utilities folder of your Applications folder.
  3. Type or paste one of the following commands in Terminal. These assume that the installer is still in your Applications folder, and MyVolume is the name of the USB flash drive or other volume you're using. If it has a different name, replace MyVolume in these commands with the name of your volume.
    Catalina:*
    Mojave:*

    High Sierra:*
    Sierra:
    El Capitan:
  4. Press Return after typing the command.
  5. When prompted, type your administrator password and press Return again. Terminal doesn't show any characters as you type your password.
  6. When prompted, type Y to confirm that you want to erase the volume, then press Return. Terminal shows the progress as the bootable installer is created.
  7. When Terminal says that it's done, the volume will have the same name as the installer you downloaded, such as Install macOS Catalina. You can now quit Terminal and eject the volume.

* If your Mac is using macOS Sierra or earlier, include the --applicationpath argument, similar to the way this argument is used in the commands for Sierra and El Capitan.

Use the bootable installer

After creating the bootable installer, follow these steps to use it:

  1. Plug the bootable installer into a compatible Mac.
  2. Use Startup Manager or Startup Disk preferences to select the bootable installer as the startup disk, then start up from it. Your Mac will start up to macOS Recovery.
    Learn about selecting a startup disk, including what to do if your Mac doesn't start up from it.
  3. Choose your language, if prompted.
  4. A bootable installer doesn't download macOS from the Internet, but it does require the Internet to get information specific to your Mac model, such as firmware updates. If you need to connect to a Wi-Fi network, use the Wi-Fi menu in the menu bar.
  5. Select Install macOS (or Install OS X) from the Utilities window, then click Continue and follow the onscreen instructions.

On Monday Apple finally unveiled to the world the next iteration of OS X, Mavericks. A developer preview of the new operating system is available now as a Mac App Store download for registered developers. Delivering Mavericks via a download is super conveient and easy for everyday users but can be unhelpful in several troubleshooting or advanced OS modification situations. The only way to obtain a bootable OS X Mavericks USB flash drive is to create your own:

The Marek Bell blog notes that creating a bootable flash drive of Mavericks is a bit more intricate than Mountain Lion because “it is no longer possible to simply restore the InstallESD.dmg to get a bootable image for USB / Flash drive installation.” But there is a way around this obstacle, which Marek outlines in his thorough walkthrough of creating a bootable OS X Mavericks flash drive. You will need at least a 8GB Flash Drive (USB 3.0 is obviously a better choice).

  1. You are going to need to see some hidden files for this. So start by opening Terminal.app and pasting in the following (don’t worry, we’ll undo this change when we are done)…defaults write com.apple.Finder AppleShowAllFiles YESkillall Finder
  2. Download the installer as normal from the app store. (At time of writing this is only possible for those with access to the developer previews).
  3. After download you will have the ‘Install OS X 10.9′ app in your /Applications folder. Right-click it and select ‘Show Package Contents’.
  4. Navigate to the Contents/SharedSupport. There you will see the InstallESD.dmg file. Unfortunately, you can’t just grab it and restore it. Instead double-click it to mount it.
  5. You should now see the normally hidden BaseSystem.dmg file in the mounted volume.
  6. Open Disk Utility and restore the source BaseSystem.dmg to the destination of your USB drive.
  7. Now open up the restored USB volume (default name is OS X Base System) and navigate to System/Installation. In there you will see an alias for Packages. Delete this alias.
  8. Copy the full Packages folder from the root of the mounted InstallESD volume (the same place you got the BaseSystem.dmg file) to the USB volumes System/Installation folder. Basically, replace the Packages alias you just deleted with the real Packages folder from the original InstallESD volume.
  9. The USB drive should now be bootable. So simply restart, hold down the Option key (Alt) when booting with the USB drive in your machine, and you should get the option to boot from the USB drive.
  10. Remember, to rehide the normall hidden files just repeat step 1 but change YES to NO.
