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
Basically, older Mac OS X CD's have two main partitions. One with the main install (HFS+) and another one with Boot Camp drivers for Windows (FAT32 or just a standard CD format). If you look in the ISO or DMG in the archive.org explorer, it can't read HFS+, only the standard, FAT32 or CD format. That's why it seems like there are only.

- A USB flash drive or other secondary volume formatted as Mac OS Extended, with at least 14GB 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
- Connect the USB flash drive or other volume that you're using for the bootable installer.
- Open Terminal, which is in the Utilities folder of your Applications folder.
- 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
MyVolumein these commands with the name of your volume.
Big Sur:*
Catalina:*
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:
- Press Return to enter the command.
- When prompted, type your administrator password and press Return again. Terminal doesn't show any characters as you type your password.
- When prompted, type
Yto confirm that you want to erase the volume, then press Return. Terminal shows the progress as the volume is erased. - 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.
- 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.
Use the bootable installer
Determine whether you're using a Mac with Apple silicon, then follow the appropriate steps:

Download Mac Os X Install Dvd
UPDATE: Apple has changed the process for creating a USB installer with OS X Mavericks and the method below no longer works. For OS X Mavericks, see this updated process.
With the release of OS X 10.7 Lion in 2011, Apple officially abandoned physical media for its operating system installations. Instead of a traditional disc, customers could now purchase and download OS X directly from the Mac App Store. This approach brought many benefits, such as not having to keep and safeguard a physical disc, immediate access to the OS when purchased instead of having to wait in line, and server-side updates to the downloadable installer so that the most current version of OS X is always installed when updating new machines.
But what if you’ve just installed a new hard drive in your Mac and have no version of OS X with the Mac App Store? Or what if you don’t have a reliable Internet connection? In these cases, it’s always best to have a physical local copy of the OS X installer. Here’s how to create your own USB or DVD Installer for OS X.
First, you’ll have to purchase a copy of OS X from the Mac App Store if you don’t already have one. Note that you can always re-download the version of OS X that came with your Mac for free.
As of the date of this article, OS X 10.8 Mountain Lion is the current OS, although the recently-announced OS X 10.9 Mavericks is right around the corner. If you’ve already purchased OS X, open the Mac App Store and head over to the “Purchases” tab. Find your desired version of OS X in the list and click the “Download” button to the right.
OS X is a multi-gigabyte file so the download process may take a while depending on your connection speed. Once it’s complete, the OS X Installer will automatically launch. Quit it by pressing Command+Q; we don’t need the installer application, just what’s inside it.
Open Finder and navigate to your Applications folder. Here you’ll find an app called “Install OS X 10.8 Mountain Lion” or something similar depending on the version of OS X you downloaded from the Mac App Store. Right-click (or control-click) on this file and select “Show Package Contents.” This will reveal the “guts” of the Installer’s application package.
Drill down to Contents > SharedSupport and find the “InstallESD.dmg” file. This is the disk image we’ll need to create a local OS X installation disc or USB drive. Copy it from the installer package to your Desktop.
Now you’ll need to decide what you’d like to use for your installation media. A USB drive is fast and durable, but you can also burn the image to a bootable dual-layer DVD. An external hard drive is also an option, although you’d want to create a partition specifically for the OS X Installer so as not to waste the entire drive’s capacity. For our example, we’ll use a USB drive.
Create an OS X USB Installer
Mount your drive or disc of choice to your Mac and launch Disk Utility. Find your target drive in the list on the left and select the “Restore” tab on the right. You’ll see two fields: Source and Destination. Drag the InstallESD image from your Desktop and drop it over the Source box, then drag the USB drive from the list in Disk Utility and drop it on the Destination box.
This is telling Disk Utility that we want to take the contents of the OS X Installer image and copy it exactly to our USB drive. Press Restore to start the process. Disk Utility will warn you that this process will delete the contents of your USB drive and ask you for confirmation. Press Erase. Disk Utility will then ask for an administrator password. Enter it and then sit back and wait for the restore to complete.
Create an OS X Install DVD
Mac Os X Install Disc Download
To create an Install DVD, insert a blank dual-layer DVD and open Disk Utility. Choose “Images” from the Menu Bar, and then “Burn.” Disk Utility will ask you which image you’d like to burn. Navigate to your Desktop and choose the InstallESD file you copied earlier, then click “Burn” to start the process.
Once either step is complete, you’ll have a bootable OS X Installer that you can use to quickly upgrade your Macs in the future without having to download the installer from the Mac App Store.
To use it, insert your disc or attach your USB drive to your Mac. Then reboot the Mac while holding down the Alt/Option key on your keyboard. Keep holding the key until the Mac boot manager launches and shows you the available boot disks. Choose your DVD or USB installer and press Return. The OS X installer will now launch and you will have the option of performing restore operations or wiping the Mac’s drive and installing a fresh copy of OS X.
