Installing macOS from a USB drive is a convenient and efficient way to upgrade or install the operating system on your Mac. Whether you’re a beginner or an experienced user, this guide will walk you through the process step by step. Follow these instructions to install macOS from a USB drive without any hassle.
Step 1: Prepare the USB Drive
Before you begin, make sure you have a USB drive with at least 16GB of storage space. You’ll need to format the drive as an MS-DOS (FAT32) partition. To do this, plug in your USB drive and open Disk Utility. Select the drive from the list on the left, then click the “Erase” button. Choose “MS-DOS (FAT32)” as the format and click “Erase” again to confirm.
Step 2: Download the macOS Installer
Next, download the macOS installer from the Apple website. Go to https://www.apple.com/macos/mojave/download/ and click the “Download” button. Once the download is complete, open the downloaded file to start the installer.
Step 3: Create a Bootable Installer
Open the macOS installer and select your USB drive from the list of available drives. Click the “Install” button, and the installer will begin copying the necessary files to your USB drive. This process may take some time, so be patient.
Step 4: Boot from the USB Drive
Restart your Mac and hold down the Option (Alt) key while it boots up. This will bring up the Startup Manager, where you can select the USB drive as your startup disk. Once the USB drive is selected, your Mac will boot from it and display the macOS installer.
Step 5: Install macOS
Follow the on-screen instructions to install macOS on your Mac. You’ll be prompted to select the disk where you want to install macOS, and then you can choose the installation type. Once you’ve made your selections, click “Install” and wait for the installation process to complete.
Step 6: Set Up Your Mac
After the installation is finished, your Mac will restart. You’ll be prompted to set up your Mac for the first time. Follow the on-screen instructions to create a user account, set your preferences, and finish the setup process.
Congratulations! You’ve successfully installed macOS from a USB drive. This method is a great way to upgrade or install macOS on your Mac, and it’s much faster than using an optical disk. Enjoy your new macOS installation!
