Though many people will disagree, installing an operating system like macOS isn't such a daunting task. If you're willing to follow the prescribed steps, you can do it even without having the expertise of a systems administrator. What makes it confusing is that there are usually several ways to clean install, re-install or upgrade macOS. Each type of installation requires a slightly different approach. In this article, we'll outline one of the simplest ways to clean install macOS Mojave from a USB flash drive. It's split up into four parts. Read each one carefully and make sure you understand what to do.

Part 1: Download macOS Mojave or High Serria DMG File

DMG is the format that Apple now uses for packaging software as a disk image. It's somewhat similar in function to ISO for Windows environments, but there are many differences as well. The one thing they can both do is to be burned as bootable media so an OS can be installed from a portable storage medium like a pen drive.

To download a macOS DMG file, you'll need to go to the Mac App Store and look at your Purchased section. If you already have it installed on that machine, it will appear there. You can also search for a particular version in the store. Make sure that once you download the file, it doesn't automatically start the installation. If it does, quit the process. You need the installation files, which will be deleted if the OS is installed.

Part 2: Burn macOS DMG File to USB Drive

This step requires some care because you can't create bootable media by just copying a DMG to a USB stick. You will need a disk authoring software that can write the DMG file with all relevant boot information to make it bootable. If you cannot boot from the drive you create in this step, you can't proceed with the installation. You can use the third-party apps to burn DMG to USB and follow the steps shown below:

Step 1: Get the DMG file from the Mac App Store.

Step 2: Install and launch DMG to USB burning utility such as UUByte DMG Editor, and insert a USB drive with at least 12GB of space (for macOS 10.14 Mojave; some require up to 16GB.) Since the drive will be formatted for the macOS installation, make sure you back up any important information that's already stored there.

Note: Your USB may need to be formatted with Disk Utility before it can be used to create bootable media. To do this, go to your USB drive within Disk Utility and click on the button or tab that says Erase. Now fill out Name, Format and Scheme fields, click Erase and Done. The format should be set to Mac OS Extended (journaled) and the scheme, if required, should be GUID Partition Map.

Step 3: Import the macOS installer and click the Burn function after selecting the appropriate USB drive.

Step 4: You may need to specify certain parameters such as burn speed, but in most applications, you can leave the default values as they are.

What you now have is a bootable USB drive containing the macOS installation files in the DMG format. The next step is to boot your Mac from this installer, and there's a special way to do that.

Part 3: Boot Mac from USB

You can now insert your USB drive into the Mac you want to install macOS on. Restart the Mac, but when you hear the startup chime, hold down the Option (alt) key on your Mac until you see the Startup Manager. Several drives will be displayed, but only the ones that have bootable media installed. Pick your USB drive using a double-click with the mouse pointer or by using the arrow keys and Return (enter) on a keyboard. Now the Mac is booting from external USB.
