Whether you're a seasoned techie or a beginner, this guide will walk you through the entire process of creating a bootable USB and using it to boot your MacBook Air.
In this article, we’ll cover the steps to create a bootable USB, how to boot from it, and some common troubleshooting tips. By the end, you'll have the knowledge to easily use your USB drive as a tool for your MacBook Air.
1. Creating a Bootable USB Drive for Your MacBook Air
The first step in booting your MacBook Air from a USB is creating a bootable USB drive. This is typically done using macOS recovery tools or third-party software, and it requires a USB drive with at least 16GB of storage. Here’s how you can create a bootable USB:
1.1 Preparing Your USB Drive
Before you start, make sure you have a clean USB drive with at least 16GB of storage. All data on this drive will be erased during the process, so back up anything important beforehand.
1.2 Download macOS Installation Files
To create a bootable USB drive, you’ll first need to download the macOS installation files from the Mac App Store. Simply search for the latest macOS version, such as macOS Ventura, and download it to your MacBook Air.
1.3 Using Terminal to Create a Bootable USB
Once you have the installation files, you’ll need to use the Terminal to create a bootable drive. Open Terminal and type the following command (replace “MyVolume” with the name of your USB drive):
sudo /Applications/Install macOS [version] .app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume
Press Enter, then follow the prompts to confirm and create the bootable USB. This process may take some time, depending on the speed of your USB drive.
2. How to Boot Your MacBook Air from USB
Now that you have a bootable USB drive, it’s time to boot your MacBook Air from it. Here’s how to do it:
2.1 Insert the Bootable USB Drive
Insert the bootable USB drive into your MacBook Air’s USB port. Ensure the USB is properly connected and recognized by the Mac.
2.2 Restart Your MacBook Air
Next, restart your MacBook Air. As soon as it powers up, immediately press and hold the Option (Alt) key. This will bring up the boot manager screen, where you can select the USB drive as the boot device.
2.3 Select Your Bootable USB
Once the boot manager appears, you will see several options. Use the arrow keys to select your USB drive, then press Enter to boot from it.
2.4 Install macOS or Run Diagnostics
Once your MacBook Air boots from the USB, you’ll be presented with several options. You can either install macOS by selecting "Install macOS," or you can run diagnostics or repair tools if needed. This is useful for troubleshooting and fixing issues without affecting your MacBook Air’s main operating system.
3. Troubleshooting Common Issues
Sometimes, booting from a USB drive might not go as smoothly as expected. Here are some common issues and solutions:
3.1 USB Not Showing Up
If your USB drive doesn’t show up during boot, make sure it’s formatted correctly and contains the macOS installation files. If necessary, reformat the USB drive using Disk Utility and try again.
3.2 “No Bootable Device Found” Error
This error can occur if the USB drive isn’t recognized as a bootable device. Ensure that the macOS installer was created correctly on the USB drive. If it was created improperly, repeat the process using the correct steps.
3.3 Boot from USB Without Option Key
If the Option key isn’t working, you can try using the Startup Manager by holding down the Command + R keys during startup to access macOS recovery. You can also reset the NVRAM (Non-Volatile Random Access Memory) by holding down Option + Command + P + R when restarting.
