Are you looking to install macOS X on a new Mac or even dual-boot your Windows PC? Or perhaps you need to troubleshoot a Mac issue and require a bootable macOS installer? Regardless of the reason, knowing how to create a USB bootable macOS X on Windows is a valuable skill.
This comprehensive guide will walk you through the process step-by-step, making it easy for even novice users to create their own bootable macOS installer. We’ll cover everything from the necessary tools and downloads to troubleshooting tips, ensuring a smooth and successful experience.
What You’ll Need
Before we begin, let’s gather the essential tools and files:
- Windows PC: You’ll need a Windows PC to create the bootable USB drive.
- macOS Installer: Download the macOS installer file from the Mac App Store (or from a trusted source). You can find the installers for various macOS versions, including Catalina, Mojave, High Sierra, and Sierra, on the Apple website.
- USB Drive: Choose a USB drive with at least 8GB of storage space. Ensure it’s empty or has data you’re willing to erase, as the process will format the drive.
- Third-Party Tool: We’ll be using a free and reliable tool called **TransMac** to create the bootable USB drive. You can download it from their website.
Downloading the macOS Installer
The first step is to download the macOS installer file. Here’s how:
1. Open the Mac App Store: On your Mac, open the App Store application.
2. Search for macOS: In the search bar, type “macOS” and press Enter.
3. Select the Desired Version: From the search results, choose the macOS version you want to install.
4. Download the Installer: Click the “Get” button to download the installer file.
If you’re unable to download the installer from the Mac App Store, you can find older versions on the Apple website. Be sure to download the installer from a trusted source to avoid malware or corrupted files.
Preparing the USB Drive
Now, let’s prepare the USB drive to be bootable:
1. Connect the USB Drive: Connect the USB drive to your Windows PC.
2. Launch TransMac: Open the TransMac application.
3. Format the Drive: In TransMac, select the USB drive from the list of available drives. Click the “Format Disk” button and choose the following settings:
- File System: Mac OS Extended (Journaled)
- Volume Name: Give your bootable drive a descriptive name (e.g., “macOS Installer”).
4. Confirm Formatting: Click “Format” to proceed. This will erase all data on the USB drive, so make sure you’ve backed up any important files.
Creating the Bootable USB Drive
With the USB drive formatted and ready, we can now create the bootable installer:
1. Open TransMac: Launch TransMac if you haven’t already.
2. Select the USB Drive: Select your USB drive from the list.
3. Mount the Installer: Drag and drop the macOS installer file (DMG file) onto the TransMac window. This will mount the installer image.
4. Restore Disk: Click the “Restore Disk” button in TransMac.
5. Select Source and Destination: Choose the mounted installer image as the source and your USB drive as the destination.
6. Start Restoration: Click “Restore” to begin the process. This may take some time, depending on the size of the installer file and your computer’s speed.
Verifying the Bootable Drive
Once the restoration process is complete, it’s essential to verify that the USB drive is bootable:
1. Eject the USB Drive: Safely eject the USB drive from your Windows PC.
2. Connect to Mac: Connect the USB drive to your Mac.
3. Restart the Mac: Restart your Mac and hold down the **Option** key (or **Alt** key) during startup.
4. Select the USB Drive: You should see the USB drive listed as a bootable option. Select it and press Enter.
If everything is working correctly, your Mac should boot from the USB drive and display the macOS installer screen.
Troubleshooting Tips
If you encounter any issues during the process, here are some common troubleshooting tips:
- Check USB Drive Compatibility: Ensure that your USB drive is compatible with your Mac and that it’s not a USB 3.0 drive. Older Macs might not support USB 3.0 drives for booting.
- Download a Different Installer: Try downloading a different macOS installer version. Sometimes, older or newer installers might be incompatible with your computer.
- Try a Different USB Drive: Use a different USB drive and try the process again.
- Run Disk Utility: If your Mac fails to boot from the USB drive, run Disk Utility (from the macOS installer) and check for errors on the USB drive.
- Verify the USB Drive is Bootable: Check if the USB drive is formatted correctly and if the installer image was restored properly.
