How to Install macOS on Mac from USB Drive (Normal Way)

In this tutorial, we will guide you through the process of installing macOS from a USB drive. This method is ideal for those who want to perform a clean install of macOS on their Mac when it's not booting into desktop or when they need to reinstall the operating system.

Step 1: Prepare Your Mac

Before you start, make sure your Mac is turned off and the power cord is connected. Press the Power key to turn it on, then immediately press the Command (⌘) and R keys simultaneously. This will boot your Mac into Recovery mode. If you're using macOS Catalina, you can also use a recovery USB drive, such as 'mac os catalina recovery usb'.

Step 2: Select Disk Utility

Once in Recovery mode, click on the Utilities button in the top menu bar and select Disk Utility from the dropdown list. This will open the Disk Utility window.

Step 3: Format the Hard Drive or SSD

In the Disk Utility window, select the hard drive or SSD that you want to format and click on the 'Erase' tab. Then, select the option to erase the disk and follow the prompts to complete the process.

Step 4: Select the Bootable USB Drive

After formatting your hard drive or SSD, insert a macOS bootable USB drive into one of your Mac's USB ports. The Startup Manager will automatically detect the bootable devices attached to your Mac, including the external USB drive.

Step 5: Install macOS from the Bootable USB Drive

Select the bootable USB drive and click on the 'Install macOS' button. Follow the prompts to agree to the terms and conditions, and wait for the installation process to complete.

That's it! With these simple steps, you should be able to install macOS from a USB drive using the normal way. If you encounter any issues during this process, don't worry - we have also provided a troubleshooting guide to help you resolve common problems.
