Why You Need to Make A Bootable Drive Mac
Creating a bootable drive on your Mac comes with numerous benefits. Firstly, it allows you to quickly and easily install or reinstall the operating system. This can be especially useful when your Mac is experiencing software issues or when you are upgrading to the latest macOS version.
Secondly, having a bootable drive provides you with a backup option in case your Mac’s internal drive fails or becomes unresponsive. With a bootable drive, you can access your files, perform repairs, or even transfer your data to a new Mac, ensuring that you don’t lose any important information.
Lastly, a bootable drive allows you to troubleshoot and perform advanced system tasks. Whether you need to reset your Mac’s password, repair disk errors, or recover data from a damaged drive, a bootable drive gives you the necessary tools and utilities to tackle these challenges effectively.
Now that we understand the importance of having a bootable drive on your Mac, let’s dive into the different methods you can use to create one.
Method 1: Using Disk Utility
Creating a bootable drive using Disk Utility is a straightforward process. Before we begin, it’s important to note that this method erases all data on the USB drive you’re using. Make sure to backup any important files before proceeding.
Step 1: Connect your USB drive to your Mac.
Step 2: Open "Disk Utility" on your Mac. You can find it in the "Applications" folder under "Utilities."
Step 3: In the Disk Utility window, select your USB drive from the list on the left-hand side.
Step 4: Click on the "Erase" button at the top of the Disk Utility window.
Step 5: Choose a name for your USB drive and select the appropriate format. For a bootable macOS installer, select "Mac OS Extended (Journaled)" as the format.
Step 6: Click on the "Erase" button to erase the contents of the USB drive and format it.
Step 7: Once the formatting is complete, open "Finder" and navigate to your Applications folder.
Step 8: Locate the "Install macOS [version]" application. This is the macOS installer file that you want to copy to the USB drive.
Step 9: Right-click on the "Install macOS [version]" application and select "Show Package Contents."
Step 10: Open the "Contents" folder, then the "Resources" folder.
Step 11: Look for a file named "createinstallmedia" and drag it to the Terminal window.
Step 12: In the Terminal window, add "–volume" followed by a space, then drag the USB drive from the Finder onto the Terminal window. Press Enter to start the process.
Step 13: Type your administrator password when prompted and press Enter.
Step 14: The Terminal will display the progress of the process. This may take some time, depending on the speed of your USB drive.
Once the process is complete, you will have a bootable USB drive containing the macOS installer. You can use this drive to install or reinstall macOS on any compatible Mac.
| Pros | Cons |

Method 2: Using Terminal
If you prefer using Terminal instead of Disk Utility, you can create a bootable drive using the command-line interface. This method requires more manual input but gives you additional control over the process. As with the previous method, ensure that you back up any important data before proceeding.
Step 1: Connect your USB drive to your Mac.
Step 2: Open Terminal on your Mac. You can find it in the "Applications" folder under "Utilities."
Step 3: Type the following command and press Enter:
diskutil list
This command will display a list of all connected drives on your Mac.
Step 4: Identify your USB drive from the list. It will have a name similar to "/dev/diskX" (where X is a number).
Step 5: Type the following command and press Enter, replacing "/dev/diskX" with the appropriate disk number for your USB drive:
diskutil eraseDisk JHFS+ MyUSB /dev/diskX
This command erases the contents of the USB drive and formats it as a macOS Extended (Journaled) volume named "MyUSB".
Step 6: Once the formatting is complete, type the following command and press Enter to download the macOS installer file:
sudo /Applications/Install macOS [version].app/Contents/Resources/createinstallmedia --volume /Volumes/MyUSB --nointeraction
Replace "[version]" with the appropriate macOS version, and "MyUSB" with the name you chose for your USB drive.
Step 7: Type your administrator password when prompted and press Enter.
Step 8: The Terminal will display the progress of the process. This may take some time, depending on the speed of your USB drive.
Once the process is complete, you will have a bootable USB drive containing the macOS installer.
| Pros | Cons |
|---|---|
| 1. Provides more manual control over the process. | 1. Erases all data on the USB drive. |

Step 6: Double-check that the correct image and drive are selected, then click on the "Flash!" button.
Step 7: Enter your administrator password when prompted and click on "OK."
Step 8: "Etcher" will start the process of creating the bootable drive. This may take some time, depending on the speed of your USB drive.
Once the process is complete, you will have a bootable USB drive containing the macOS installer.

Step 1: Shut down your Mac completely.
Step 2: Press and hold the "Option + Command + R" keys simultaneously.
Step 3: Keep holding the keys until you see a spinning globe or a utilities window on your screen.
