why not create a clean virgin (and updated)
Mac OS X ASR disc image using a firewire drive, carbon copy
cloner and netrestore?

Here is how;

1. Install OS X (with full options, BSD, your chosen Languages etc)
onto a clean firewire drive partition (need a firewire bootable mac)

2. Boot, create user, test, update (Apple CDs are out of date anyway)

3. Carbon Copy Cloner your beautiful OS X to an ASR compatible Disc image
with ASR options enabled.

4. Test a restore to a spare partition.

Then all you need to do in the future to restore is as follows:

- Boot off a OS X mac (by firewire drive, target disk mode etc)
- run NetRestore, clone from your ASR disc image
- reboot into new OS X. (restore can take less than 5 minutes)

This technqiue is hundreds of time faster, better, more up-to-date than
using the ancient art of inserting a CD/DVD installer, booting, installing,
rebooting, creating a user, running updates, restart, repeat etc etc
And has numerous applications to long too explain here.
Essential techniqnue if you are running more than a couple of
OS X macs at home or at work..

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.

What you need to create a bootable installer

Bootable
  • A USB flash drive or other secondary volume, formatted as Mac OS Extended, with at least 12GB of available storage
  • A downloaded installer for macOS Big Sur, Catalina, Mojave, High Sierra, or El Capitan

Download macOS

  • Download: macOS Big Sur, macOS Catalina, macOS Mojave, or macOS High Sierra
    These download to your Applications folder as an app named Install macOS [version name]. If the installer opens after downloading, quit it without continuing installation. To get the correct 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.
  • Download: OS X El Capitan
    This downloads as a disk image named InstallMacOSX.dmg. On a Mac that is compatible with El Capitan, open the disk image and run the installer within, named InstallMacOSX.pkg. It installs an app named Install OS X El Capitan into your Applications folder. You will create the bootable installer from this app, not from the disk image or .pkg installer.

Use the 'createinstallmedia' command in Terminal

  1. Connect the USB flash drive or other volume that you're using for the bootable installer.
  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 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.

Big Sur:*

Catalina:*

Mac

Mojave:*

High Sierra:*

El Capitan:

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


After typing the command:

  1. Press Return to enter the command.
  2. When prompted, type your administrator password and press Return again. Terminal doesn't show any characters as you type your password.
  3. When prompted, type Y to confirm that you want to erase the volume, then press Return. Terminal shows the progress as the volume is erased.
  4. After the volume is erased, you may see an alert that Terminal would like to access files on a removable volume. Click OK to allow the copy to proceed.
  5. When Terminal says that it's done, the volume will have the same name as the installer you downloaded, such as Install macOS Big Sur. You can now quit Terminal and eject the volume.
