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.

Before you dive into this guide, you’ll need a few things: A broken Mac computer with Mac OS X or macOS (version 10.12 or later). A trial copy of the TransMac software. One high quality USB flash drive with 16GB of storage. A copy of Apple’s macOS (DMG file).
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.
How to Create Bootable USB on Mac: There are a few general guidelines that can help get your machine started which are mentioned above, regardless of the OS the user prefers. Here are the methods to create a bootable USB drive on Mac. Creating a Bootable USB Using Terminal. To create your own Mac OS X recovery USB drive, all you need is a 1GB or larger USB drive. If you have a USB drive larger than 1 GB, you can create a 1.5 GB or 2 GB partition for the recovery drive because the creation process will erase the whole USB drive and use all of the available space no matter how large it is and the drive will become.

What Is an OS X Recovery Disk? The OS X Recovery Disk is a native but hidden recovery volume on your Mac hard drive.

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.
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 MojaveormacOS 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.

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.

- 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:*

- 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.
Learn about selecting a startup disk, including what to do if your Mac doesn't start up from it. - Choose your language, if prompted.
- A bootable installer doesn't download macOS from the Internet, but it does require the Internet to get information specific to your Mac model, such as firmware updates. If you need to connect to a Wi-Fi network, use the Wi-Fi menu in the menu bar.
- Select Install macOS (or Install OS X) from the Utilities window, then click Continue and follow the onscreen instructions.
