Part 3: Create macOS Mojave Bootable USB Installer on Windows 10 PC
You have completed the preparation process in above steps and it is time to create a bootable Mojave USB installer from the download dmg file. Unfortunately, the USB would be bootable if just simply copying the dmg file to USB drive without additional actions because the booting code is not written to USB via file copy. Instead, you should use third-party software to help you create a macOS Mojave USB drive from DMG file.
UUByte DMG Editor is such a tool for burning dmg file to USB drive. It will copy all installation files and write boot information to USB drive as well. After burning, the USB is bootable and can be used as a media to install macOS. The following is the details for creating macOS Mojave bootable USB drive.
Step 1: Click the Download button and save the .exe file on your Windows PC; then double click it to start the installation process.
Step 2: Insert a USB drive into the PC and open DMG Editor software from desktop shortcut. Now, click Next button at the right side of Burn module.
Step 3: Now, you need to import the downloaded Mojave dmg file into the program and choose the USB drive name from drop-down menu.
Step 4: When the preparation is done, click Burn button to start burning macOS Mojave dmg file to target USB device. You have to wait for 5-10 minutes for this.
This is one of most reliable ways to create macOS Mojave bootable USB drive on a Windows PC. You can use DMG Editor on latest Windows 10 as well as Windows 8/7/XP.
Part 4: Install macOS Mojave from USB Drive on Mac
After creating macOS Mojave bootable USB drive, it is the right time to install Mojave on your Mac. If possible, make sure taking a backup of important data on your Mac. The installation process will format the drive and this will delete all your personal data and apps from Mac.
To get started, please connect the USB drive to Mac and power on the computer. Keep pressing the Option key and you see the Startup Manager in a few seconds. Click on the USB drive name with your mouse to enter into installation page. Next, select the internal drive and finally click Continue button to begin the installation process.
Note: For installation on a Hackintosh, you need additional tool to configure the boot loader, such as OpenCore or Clover. After that, plug the USB into Hackintosh and set USB as the first boot device in BIOS. By doing this, you will manage to get into Mojave install wizard.
