The Apple MacBook is one of the best laptops on the market due to its sleek design, powerful processing, and reliable performance. But if you ever need to start it up from a USB drive instead of the usual hard disk, the process is not necessarily a straightforward one. This Ultimate Guide outlines the steps you’ll need to take to boot your MacBook from USB safely and easily.
The first step in the process is to format the USB drive. This will prepare it to be used as a boot drive. To format the drive, insert it into a USB port, launch the Disk Utility program, and select the drive as the device to format. Choose the ‘FAT’ formatting option and click on the ‘Format’ button.
Once the USB drive is formatted properly, you need to create a bootable image of the Mac OS X on the drive. Download the OS X installer from the Apple website and save it on your hard drive. Open the Disk Utility program again and select the USB drive. Select the Installer option from the left panel and choose the OS X image file. Click the ‘Create’ button and the image will be written to the USB drive.
The next step is to install the bootloader on the USB drive so that it can boot from the drive. To do this, launch the Terminal app on your Mac, and type the command ‘sudo bless –mount’ followed by the path to the USB drive. This will install the bootloader on the drive.
Finally, you need to tweak a few settings on your MacBook to enable it to boot from the USB drive. Launch the System Preferences app and select the ‘Startup Disk’ option. Select the USB drive as the boot drive and click ‘Restart’ to boot from the drive.
These steps should enable you to boot your MacBook from a USB drive quickly and safely. Keep in mind that the USB drive you’re using must have enough storage capacity to hold the OS X installer, and that you’ll need to reinstall the OS X image after every boot. Follow the instructions above to enjoy the flexibility offered by booting your MacBook from a USB drive.
