Understanding How to Boot from USB on a Mac
Booting a Mac from a USB drive can be a useful tool for a variety of reasons, including installing a fresh operating system, running diagnostics, or using a bootable backup. The process involves starting up your Mac using a USB drive instead of the internal hard drive or SSD. This method can be particularly helpful if your Mac is experiencing software issues or if you're setting up a new system.
Before attempting to boot your Mac from a USB drive, it’s important to understand the basics of how your Mac handles boot drives. When you start your Mac, it looks for bootable devices. If you’ve created a bootable USB drive, your Mac will detect it during the startup process, allowing you to boot from it.
Preparing Your USB Drive for Booting
To successfully boot from a USB drive, you'll first need to create a bootable USB drive. This process is relatively simple but requires a few specific steps. Here’s how to prepare your USB drive:

1. Format the USB Drive
Start by formatting the USB drive to the correct file system. You can use Disk Utility on your Mac to format the USB drive as Mac OS Extended (Journaled) or APFS, depending on your macOS version. Be sure to back up any important data on the USB drive as formatting will erase all existing files.
2. Download the macOS Installer
Next, you’ll need to download the macOS installer from the Mac App Store. The installer is available for free and allows you to create a bootable USB drive with the latest version of macOS. Once downloaded, the installer will be placed in your Applications folder.
3. Create the Bootable USB Drive
Once the installer is ready, you can use the Terminal to create the bootable drive. The process involves using a command line script to copy the installer to the USB drive. This can be done using the 'createinstallmedia' command, which is included in the macOS installer.
How to Boot Your Mac from USB Drive
Now that your USB drive is ready, it’s time to boot your Mac from it. Here’s a step-by-step guide on how to boot your Mac from the USB drive:
1. Insert the USB Drive
Insert the bootable USB drive into one of the USB ports on your Mac. If you're using a newer Mac with USB-C ports, you may need an adapter to connect the USB drive.
2. Restart Your Mac and Access the Boot Menu
Restart your Mac and immediately press and hold the 'Option' key. This will bring up the Boot Manager, where you can choose the device from which you want to boot.
3. Select the USB Drive
In the Boot Manager, you will see a list of bootable drives. Select your USB drive, and press Enter. Your Mac will now boot from the USB drive, allowing you to install or troubleshoot macOS as needed.
Troubleshooting Common Boot Issues
Sometimes, booting from a USB drive on a Mac can present issues. Here are some common problems and solutions:
1. USB Drive Not Recognized
If your Mac doesn't recognize the USB drive, make sure it's properly formatted and that the macOS installer is correctly copied. Also, check that the USB drive is inserted correctly and is compatible with your Mac.
2. Boot Manager Not Appearing
If the Boot Manager doesn't appear when you press the 'Option' key, try restarting your Mac and holding the key earlier. If the issue persists, your Mac may need a firmware update.
3. Errors During Installation
If you encounter errors during macOS installation from the USB drive, ensure that the USB drive is not corrupted and that it contains the correct installer files. Recreate the bootable USB drive if necessary.
