Why Boot from USB?

Before diving into the technicalities, let’s understand why booting from USB is a valuable skill. Here are some key reasons:

• Installing macOS: If you’re looking to upgrade to a newer version of macOS, or even install a fresh copy, booting from a USB drive is the way to go. It allows you to bypass any issues with your existing operating system and install a clean version.
• Troubleshooting Startup Problems: If your MacBook Air is experiencing startup issues, booting from a USB drive with a bootable macOS installer can help you diagnose and resolve the problem.
• Running Diagnostic Tools: Certain diagnostic tools, like Apple’s Disk Utility, can be run from a USB drive to check for hardware errors or repair disk issues.
• Experimenting with Different Operating Systems: Booting from a USB drive allows you to try out different operating systems, like Linux or Windows, without affecting your existing macOS installation.

Preparing Your USB Drive

The first step is to prepare your USB drive to be bootable. Here’s how:
1. Choose the Right USB Drive: Select a USB drive with enough storage space for the operating system or files you want to boot from. A minimum of 8GB is generally recommended.
2. Format the USB Drive: You’ll need to format the USB drive to be compatible with your MacBook Air. Here’s how:

• Open Disk Utility: Search for “Disk Utility” in Spotlight.
• Select Your USB Drive: In the Disk Utility window, select your USB drive from the list on the left.
• Format the Drive: Click the “Erase” button and choose the following options:

Creating a Bootable USB Drive

Now that your USB drive is ready, you need to create a bootable installer. Here’s how:
