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

• 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

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.

Catalina:*

Mojave:*

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.

A bootable installer doesn't download macOS from the internet, but it does require an internet connection to get firmware and other information specific to the Mac model.

For information about the createinstallmedia command and the arguments you can use with it, make sure that the macOS installer is in your Applications folder, then enter the appropriate path in Terminal:

Install El Capitan App

As with prior versions of OS X, the new version 10.11 “El Capitan” is available as a free purchase from the App Store, and should then download and run to allow you to upgrade your system. If all goes well, you should see the OS X installation window that instructs you to begin the upgrade process, but there may be instances where this does not appear, or does not work when you attempt the install.

OS X El Capitan remains available for Mac computers that can't upgrade to macOS Catalina, Mojave, High Sierra or Sierra, or that need to upgrade to El Capitan first. Then double-click the file named Install OS X El Capitan. Click Continue and follow the on-screen instructions. My problem is that my Mac starts up to the 'El Capitan' installer. After restarting several times, OS X is still on screen telling me that 'no packages were eligible for install'.

First, the OS X installer should run automatically, but if not then you can try running it manually:

1. Go to the Applications folder
2. Open the program called “Install OS X El Capitan”
3. Follow the on-screen instructions.

If this program is missing or will not run, then move it to the trash and empty the trash, followed by re-downloading it from the App Store.

An alternative approach is to create a dedicated installation drive from the El Capitan installer, and use that to install the upgrade. For this, you will need a spare external drive (USB drive, or hard drive) that is at least 8GB in size, and then perform the following steps:

1. Attach the drive to your Mac
2. Use Disk Utility to format it to HFS+ with a GUID partition scheme, naming it INSTALLER
3. Open the OS X Terminal and run the following command (copy and paste all 5 lines):

Press Enter to run the pasted command, and supply your password when prompted (it will not show when typed). Note that if you get any errors, be sure your USB drive is formatted and named “INSTALLER” so the command will properly target it. You will also need to have first downloaded the OS X El Capitan installer from the App Store, and have this present in your Applications folder.

The Terminal may take a while to complete this step, but when done you can reboot your Mac and hold the Option key to show the boot menu, and then select the El Capitan installation drive you just created to run the installer and upgrade your Mac’s internal hard drive.

/mac-os-catalina-iso-download-for-vmware/. If the procedure still fails with an error, then hopefully you have a full system backup ready, which you can restore to your Mac using the option to restore from a Time Machine backup in the OS X Recovery partition, or whatever cloning software you use. When done, attempt the above procedures to try again.

Check compatibility

You can upgrade to OS X El Capitan from OS X Snow Leopard or later on any of the following Mac models. Your Mac also needs at least 2GB of memory and 8.8GB of available storage space.

El Capitan Not Eligible For Install Data

To find your Mac model, memory, storage space and macOS version, choose About This Mac from the Apple menu . If your Mac isn't compatible with OS X El Capitan, the installer will let you know.

Make a back-up

Before installing any upgrade, it’s a good idea to back up your Mac. Time Machine makes it simple, and other back-up methods are also available. Learn how to back up your Mac.
