Download macOS

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

macOS Catalina, macOS Mojave, ormacOS High Sierra
Installers for each of these macOS versions 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. Important: 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.

OS X El Capitan
El Capitan downloads as a disk image. 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. Make sure that it has at least 12GB of available storage and is formatted as Mac OS Extended.
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 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:*
El Capitan:
Press Return after typing 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 Y to confirm that you want to erase the volume, then press Return. Terminal shows the progress as the bootable installer is created.
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 command for El Capitan.

Use the bootable installer

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

Plug the bootable installer into a compatible Mac.
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.

How To Make Bootable Usb Mac Os Yosemite

Installing OS X Yosemite is as easy as downloading the installer from the Mac App Store and getting started. But there are times when you might want to create a bootable drive to run the Yosemite installer from, instead.

Installing Yosemite from a bootable drive comes in handy if you want to do a clean install - wiping your hard drive and installing a fresh copy of the operating system, for example, or if you're installing the software on multiple Macs and don't want to have to download it each time.

To do this, you'll need the Yosemite installer and you'll also need a bootable disk. You can use a USB thumbdrive with 8 GB or more storage capacity or an external USB hard disk; either will work just fine.

To download the Yosemite installer, click here. The installer is free, though you'll need to be signed in to the Mac App Store to download it. After it downloads, the installer app may automatically launch. Quit out of the installer if it does.

You'll need to make sure that external hard drive or USB drive is properly formatted for the Mac.

To format the drive for the Mac

Attach the drive to an available USB port on you Mac.
Open the Utilities folder.
Double-click Disk Utility.
Select the hard drive or USB thumbdrive from the list on the left hand side of the Disk Utility window.
Click the Erase tab. Name the drive whatever you'd like, but I'd recommend using one word, easy to remember. For the purposes of this How To, I've named it Installer. Remember it though, for the next step in our procedure.
Format it for 'Mac OS Extended (Journaled).' Click the Erase button.
Quit Disk Utility.
