If you’d like to keep files synced between a desktop and laptop, expand your storage, or have a bootable backup copy of your system, there’s a hidden feature in Disk Utility that makes it easy. Generally, booting from an external drive will be slower, even with new Thunderbolt and USB-C drives. Select Mac OS Extended (Journaled) from Format dropdown. Type BigSur or any other name you like. Make it simple because you will use this name in the next step. Click Erase and wait until the media is erased. Step 3: Making the Bootable Media. Now open Terminal and type the following command. Make sure you don’t leave any spaces.

When OS X shipped on a DVD a good number of years ago, you always had the convenience of a bootable installer—an OS X installer that could be used to boot your Mac if its own drive was having problems. But to install or reinstall a recent version of OS X, you must either download a non-bootable installer from the Mac App Store or (via OS X’s invisible, bootable recovery partition) download 6GB of installer data from Apple’s servers during the installation process. In other words, you no longer have the same safety net or convenience.

Because of this, I recommend creating your own bootable El Capitan (OS X 10.11) installer drive on an external hard drive or USB thumb drive. If you need to install El Capitan on multiple Macs, using a bootable installer drive is faster and more convenient than downloading or copying the entire installer to each computer. If you want to erase the drive on a Mac before installing El Capitan, or start over at any time, you can use a dedicated installer drive to boot that Mac, erase its drive, and then install the OS (and subsequently restore whatever data you need from your backups). And if your Mac is experiencing problems, a bootable installer drive makes a handy emergency disk.

(OS X Recovery lets you repair your drive and reinstall OS X, but to perform the latter task, you must wait—each time you use it—for the entire 6GB of installer data to download. At best, that’s a hassle; at worst, it’s hours of waiting before you can get started.)

As with previous versions of OS X, it’s not difficult to create a bootable installer drive, but it’s not obvious, either. I show you how, below.

Keep the installer safe

Like all recent versions of OS X, El Capitan is distributed through the Mac App Store: You download an installer app (called Install OS X El Capitan.app) to your Applications folder. In this respect, the OS X installer is just like any other app you buy from the Mac App Store. However, unlike any other app, if you run the OS X installer from that default location, the app deletes itself after it’s done installing OS X.

If you plan to use the OS X installer on other Macs, or—in this case—to create a bootable installer drive, be sure to copy the installer to another drive, or at least move it out of the Applications folder, before you use it to install the OS on your Mac. If you don’t, you’ll have to redownload the installer from the Mac App Store before you can use the instructions below.

What you need

To create a bootable El Capitan installer drive, you need the El Capitan installer from the Mac App Store and a Mac-formatted drive that’s big enough to hold the installer and all its data. This can be a hard drive, a solid-state drive (SSD), a thumb drive, or a USB stick—an 8GB thumb drive is perfect. Your drive must be formatted as a Mac OS Extended (Journaled) volume with a GUID Partition Table. (Follow this tutorial to properly format the drive if you’re using OS X Yosemite or older. If you’re using OS X El Capitan, use these instructions.)

Your OS X user account must also have administrator privileges.

Apple’s gift: createinstallmedia

In my articles on creating a bootable installer drive for older versions of OS X, I provided three, or even four, different ways to perform the procedure, depending on which version of OS X you were running, your comfort level with Terminal, and other factors. That approach made sense in the past, but a number of the reasons for it no longer apply, so this year I’m limiting the instructions to a single method: using OS X’s own createinstallmedia tool.

Make Bootable Usb In Mac

Starting with Mavericks, the OS X installer hosts a hidden Unix program called createinstallmedia specifically for creating a bootable installer drive. Using it requires the use of Terminal, but createinstallmedia works well, it’s official, and performing the procedure requires little more than copying and pasting.

The only real drawback to createinstallmedia is that it doesn’t work under OS X 10.6 Snow Leopard—it requires OS X 10.7 Lion or later. Though it’s true that some Macs still running Snow Leopard can upgrade to El Capitan, I think it’s safe to assume that most people installing OS X 10.11 will have access to a Mac running 10.7 or later.

(If you absolutely refuse to go near Terminal, an El Capitan-compatible version of DiskMaker X is now available, although I haven’t yet had the chance to test it.)

Making the installer drive

  1. Connect to your Mac a properly formatted 8GB (or larger) drive, and rename the drive Untitled. (The Terminal commands I provide here assume that the drive is named Untitled. If the drive isn’t named Untitled, the procedure won’t work.)
  2. Make sure the El Capitan installer (or at least a copy of it), called Install OS X El Capitan.app, is in its default location in your main Applications folder (/Applications).
  3. Select the text of the following Terminal command and copy it. Note that the window that displays the command scrolls to the right.
  4. Launch Terminal (in /Applications/Utilities).
  5. Warning: This step will erase the destination drive or partition, so make sure that it doesn’t contain any valuable data. Paste the copied command into Terminal and press Return.
  6. Type your admin-level account password when prompted, and then press Return.
  7. You may see the message “To continue we need to erase the disk at /Volumes/Untitled. If you wish to continue type (Y) then press return:” If so, type the letter Y and then press Return. If you don’t see this message, you’re already set.

The Terminal window displays createinstallmedia’s progress as a textual representation of a progress bar: Erasing Disk: 0%… 10 percent…20 percent… and so on. You also see a list of the program’s tasks as they occur: Copying installer files to disk…Copy complete.Making disk bootable…Copying boot files…Copy complete. The procedure can take as little as a couple minutes, or as long as 20 to 30 minutes, depending on how fast your Mac can copy data to the destination drive. Once you see Copy Complete. Done., as shown in the screenshot above, the process has finished.

Createinstallmedia will have renamed your drive from Untitled to Install OS X El Capitan. You can rename the drive (in the Finder) if you like—renaming it won’t prevent it from working properly.

Booting from the installer drive

You can boot any El Capitan-compatible Mac from your new installer drive. First, connect the drive to your Mac. Then, restart your Mac (or, if it’s currently shut down, start it up) while holding down the Option key. When OS X’s Startup Manager appears, select the installer drive and then click the arrow below it to proceed with startup. (Alternatively, if your Mac is already booted into OS X, you may be able to choose the installer drive in the Startup Disk pane of System Preferences, and then click restart. However, sometimes OS X installer drives don’t appear in the Startup Disk window.)

Once booted from your installer drive, you can perform any of the tasks available from the OS X installer’s special recovery and restore features. In fact, you’ll see the same OS X Utilities screen you get when you boot into OS X Recovery—but unlike with recovery mode, your bootable installer includes the entire installer.

A Universal Serial Bus or USB Drive, also known as a flash drive is a portable data storage device that includes a memory which includes a USB interface. It is typically removable and much smaller than an optical disc. Any sort of data can be stored in this device. The drives are available in various sizes and as of to date, the 2TB(Tera-Byte) flash drives in terms of storage capacity are the largest ones available in the market.

Today, these drives are one of the most consumed used devices in the world. Thanks to their portable nature, affordability, and compatibility, USB drives are being used to send and receive endless information across a surplus of networks and platforms all around the globe. This small tool has opened the world to a stream of limitless options with respect to storing, transferring, copying data, and much more. One of them includes Booting the Mac from such a device.

Part 1. Reasons for Mac Boot from USB

Booting the Mac from USB in a way gives the power back to the user. The likeliest of the reason for choosing the boot from the USB method is that your Mac won't start which denies the user access to the computer. Using an external source like the USB drive helps the user get around the problem. It provides the user access to the contents of the internal drive, assuming the data is safe and not corrupted. It also helps to repair the Mac disk with Disk Utility and other tools. Here are the top reasons why the user should choose to Boot Mac from USB:

  • Allows the user to install a different version of macOS.
  • It allows the user to test a new version before you make the decision to upgrade.
  • Allows risk-free testing of the Beta version.
  • Faster and efficient.
  • By installing older versions through USB, it permits certain Apps to run which are not compatible with the latest macOS.

Part 2. Preparations for Booting Mac from USB

To ensure a risk-free procedure certain measure should be taken:

  • The user should buy a name-brand flash drive.
  • The USB should contain 16-32GB of free space.
  • The user should scan the flash drive with some reputable Anti-Virus software.
  • The user should check to see what size of ports they have on the Mac. A 12' Mac only contains a single C-Type port.
  • Make sure to purchase the C port flash drive to avoid any inconvenience.
  • It is advised that the user should go with a USB 3.0 supported drive, with a size of 16GB to ensure a swift transfer of data.
  • The USB drive should be formatted with a supported GUID partition.
  • It should contain an OS X installer or a usable operating system to work with.

Part 3. 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

The terminal is the default gateway to the command line on a Mac. It is just like the Command Prompt feature works for MS Windows. The Terminal feature ensures a hassle-free experience for the Mac user without the conventional pointing and clicking, the user just has to type the commands and the computer does the rest. The user can find Terminal in the Applications > Utility folder or it can be checked in the finder utility.

Using the Terminal feature is the most simple way to create the bootable USB drive. The user just needs to follow one easy step which is renaming the MyVolume portion of the command with the name of the drive. The name of the drive can be changed using the Disk Utility of Mac. Here are the steps required after opening the Terminal feature to create a bootable USB drive.

  • Copy and paste the command which is suited for the version of the operating system into the Terminal window.
  • The command for MacOS Mojave is as follows:
    sudo/Applications/InstallmacOSMojave.app/Contents/Resources/createinstallmedia --volume/Volumes/MyVolume
  • Press the Return key.
  • Enter the password.
  • Confirm to erase the USB drive by typing Y followed by the Return key.
  • The terminal will erase all the data inside the drive and create the bootable USB drive.

If there is a need to install a different version of the operating system then the user just has to replace the above-underlined command with their desired version of OS. For example, if the user wants to install Mac OS Sierra instead of Mojave then they would have to replace 'Mojave.app' with 'Sierra.app' inside the command line.

Part 4. How to Boot Mac from USB Media

After creating a bootable USB drive, the user simply needs to plug the created drive into the open port on the 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 startup disk when the option appears.
  • The system will start the boot process off the USB drive.
  • Install the operating system from the macOS utilities.
  • Data can be restored by using the Time-Machine backup option.
