Beginning in Lion (10.7), there's a new feature in Mac OS X to assist you if things go really wrong, since you can't boot from disk anymore. This new feature is called Recovery, and it gives you a way to start 'from scratch' if you need to rebuild your Mac.

Here are the steps to boot Mac from the USB flash drive: Power on the system. Press and hold the Option (Alt) key on the keyboard when the computer starts. Select the USB drive as a. Reset your PRAM. Shut down your Mac and hold down Command-Option-P-R during boot. Wait for the chimes and let go. Check your keyboard (especially if it's a Bluetooth keyboard). Try using a wired keyboard if possible. But there are not many USB data recovery solutions for Mac users. In most cases, Mac data recovery software can help you to recover lost USB data under Mac OS. Do Your Data Recovery for Mac is the reliable Mac USB drive data recovery software that can recover deleted or lost files from USB drive under Mac OS.

There are a couple of methods for doing this, which both lead to the same place: A USB drive (8GB or larger), safely stashed in a drawer, which has a bootable OS on it, as well as an installer to put that OS on a hard drive.

First up is the 'official' method, a utility introduced with Mavericks, called Recovery Disk Assistant. This works with Lion, Mountain Lion, and Mavericks, all the versions of Mac OS that were distributed via the Mac App Store.

It can recover deleted/formatted or lost files from Mac hard drive, USB drive, memory card, external hard disk etc due to deletion, format, virus infection, partition loss, OS reinstallation, etc. All kinds of files can be recovered including photos, documents, audio, emails, folders, archives, download files, etc.
Mac Free USB Flash Drive Recovery helps you easily recover all lost missing files and folders from your USB media due to wrong deletion, format, power failure, virus infection or USB damaged, etc.

Using this method is pretty straightforward: download the Recovery Disk Assistant, plug in that USB drive, and follow the prompts. After a little while you will have a bootable backup of your OS.

First off, insert a clean USB flash drive/external hard drive on which you wish to create Mac Lion Recovery and then run the assistant application to detect the external storage device. When you click Continue, it will start copying files, required to recover Mac Lion, to your USB drive.

An alternate method that dates back to the release of Lion is Disk Maker X, formerly known as Lion Disk Maker. This is a nice wrapper for a set of Applescripts that will also create a USB drive to back up from. This was the nicest option before Apple built a utility of its own. It works much the same way as Apple's too, launch the app and follow the prompts and you end up with a USB drive you can boot from.

Keep in mind you can't install an older OS than your computer shipped with, but otherwise to use this newly minted installer all you have to do is plug in the USB drive, and hold down the Option key while the machine boots. This will give you your boot drive options, then choose the USB stick and you're all set.

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.

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.
