Prerequisites

Before embarking on the creation process, ensure the following prerequisites are met:

• Windows 10 operating system: This guide focuses on creating a bootable macOS USB drive on a Windows 10 system.
• macOS Installer: Obtain the macOS installer file from the Mac App Store or Apple’s website. This installer file is typically a DMG (Disk Image) file containing the necessary installation files.
• USB Drive: Select a USB drive with sufficient storage capacity to accommodate the macOS installer file. It’s recommended to use a drive with at least 8GB of free space.
• Third-Party Software (Optional): While not strictly necessary, using a third-party tool like Balena Etcher can streamline the process and offer a user-friendly interface.

Step-by-Step Guide

Follow these steps to create a bootable macOS USB drive on Windows 10:

Step 1: Download the macOS Installer

• Visit the Mac App Store or Apple’s website and download the macOS installer file. This file will be a DMG (Disk Image) file.
• Ensure you download the correct installer for the macOS version you intend to use.

Step 2: Format the USB Drive

• Using Disk Management: Open Disk Management by searching for it in the Windows search bar.
• Right-click on the USB drive you want to format and select Format.
• Choose FAT32 as the file system and give the drive a suitable name.
• Click Start to begin the formatting process.

Step 3: Mount the macOS Installer DMG

• Double-click the downloaded macOS installer DMG file to mount it. This will create a virtual drive on your Windows system.

Step 4: Copy the macOS Installer to the USB Drive

• Using Command Prompt: Open Command Prompt as administrator.
• Navigate to the mounted macOS installer drive using the cd command. For example, if the mounted drive is named "macOS Installer," the command would be cd /d "D:macOS Installer". Replace "D" with the drive letter of the mounted installer.
• Type the following command: xcopy /s /e /f *.* "D:USB Drive". Replace "D:USB Drive" with the actual path to your formatted USB drive. This command copies all files from the macOS installer to the USB drive.
• Wait for the process to complete.

Step 6: Copy the Boot Files (Optional)

• Using Explorer: Open File Explorer and navigate to the mounted macOS installer drive.
• Locate the "Contents/Resources/Packages/BaseSystem.pkg" file.
• Copy this file to the root directory of your USB drive.

Step 7: Test the Bootable USB Drive

• Restart your Mac and hold down the Option (⌥) key.
• Select the bootable USB drive from the list of startup devices.
• If the USB drive boots successfully, you’ve successfully created a bootable macOS USB drive.

Alternative Methods

While the above method utilizes built-in Windows tools, alternative methods offer a more streamlined approach:
