The second alternative answer involves using an older Mac capable of running Snow Leopard (OS X 10.6). Still, I would like know from Apple why they thought such a complex procedure is necessary. So, Apple evidently intends for users of newer model Intel Macs to use this new answer to retrieve the Install OS X El Capitan application. This answer is must less of a hack, because Apple explicitly inserted code into the El Capitan installer to bypass the checking of the model when executed in a 'VMware Fusion Player' virtual machine. The first alternative answer involves using a virtual machine. I have posted two alternative answers to this question. Justin reported this answer still works for Yosemite. At best, these instructions are just a hack and Apple has every right to change the InstallMacOSX.dmg file to prevent the desired results. These instructions may work as expected, if you are using an older saved version of this file. You can now quit Terminal and eject the volume.I have noticed that these instructions no longer work as expected when using the current InstallMacOSX.dmg file, which can be downloaded from either the Apple website ' How to download macOS' or the Apple website ' How to create a bootable installer for macOS'. When Terminal says that it's finished, the volume will have the same name as the installer you've downloaded, such as Install macOS Monterey.After the volume has been erased, you may see an alert stating that Terminal would like to access files on a removable volume.Terminal displays the progress as the volume is being erased. When prompted, type Y to confirm that you want to erase the volume, then press Return.Terminal doesn't show any characters as you type.

When prompted, type your administrator password.

If the volume has a different name, replace MyVolume in the command with the name of your volume. Each command assumes that the installer is in your Applications folder and MyVolume is the name of the USB flash drive or other volume you're using.

Type or paste one of the commands below into Terminal, then press Return to enter the command.

Open Terminal, which is in the Utilities folder of your Applications folder.

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