Guide to prepare macOS Sierra bootable install USB on Windows 10/8/7
NOTE: The guide was originally written to prepare macOS Sierra bootable USB but it works with the latest macOS Mojave as well.
Step 1: Connect a USB drive with at least 16 GB of storage space to your Windows PC and move all data from USB drive to a safe place as the drive will be erased while preparing macOS Mojave bootable USB.
Step 2: Visit this page of TransMac and download the latest version of TransMac software on your PC. TransMac is a paid software but the 15-day trial copy can be used to prepare bootable USB without any issues. That said, if you often need to prepare macOS bootable USB from Windows, you should go ahead and buy the software.
Once the TransMac is downloaded, double-click on the setup file to run the installer and get it installed on your PC.
Step 3: Run TransMac software as administrator. To do so, type TransMac in Start menu search box, right-click on TransMac entry in search results, and then click Run as administrator option. When you see the TransMac Trial dialog box, Click Run button.
Alternatively, you can navigate to TransMac entry in Start menu, right-click on it, and then click Run as administrator option.
Step 4: Once TransMac is launched, in the left pane of the program, you will see the connected USB drive that you want to use to prepare macOS Mojave bootable USB. Right-click on the USB drive and then click Format Disk for Mac option.
Click Yes button when you see the warning dialog box.
This is because, if you have been using a USB flash drive with Windows operating system, the USB drive is likely using MBR partition type. So we need to partition the USB drive with GPT partition first before transferring the DMG file to the USB drive.
Step 5: Clicking Yes button will open Format Drive for Mac dialog box where you need to type a name for the drive. Since we are preparing Mojave bootable USB, let’s name the drive as Mojave install drive.
When you see the warning message again, click Yes button to continue and format the drive for Mac.
Step 6: Once the format is done, right-click on the USB drive again, and then click Restore with disc image option.
Click Yes button when you see the following warning dialog box.
Step 7: Clicking the Yes button will open Restore Disk Image to Drive dialog box. Under Disk image to restore section, click the small button with drive icon on it (refer to the picture below) to browse to macOS Mojave DMG file. Select the DMG file and then click Open.
Finally, click OK button.
Step 8: When you see the warning dialog box, click the Yes button to begin preparing your macOS Sierra bootable USB. The bootable USB should be ready in about 30 minutes. In our test, the tool took close to 45 minutes, though.
Once the bootable USB of Mojave is ready, you can connect it to your Mac device and begin installing macOS Mojave from it. Good luck!
How can I make a bootable Windows installation USB on Mac OS X? After upgrading to macOS Mojave, you may find that Boot Camp Assistant is no longer supported and thus creating a bootable USB turns out to be a little bit challenging. In this tutorial we’ll show you how to create Windows 10 bootable USB from ISO on Mac, by using the Terminal or third-party software like UNetbottin.
Method 1: Create Windows 10 Bootable USB on Mac Using UNetbottin
UNetbootin is a free, open source utility that allows you to create bootable USB drives on Windows, Linux, and Mac OS X. If you’ve downloaded Windows 10 ISO image, here is how you can create a bootable Windows installer USB on Mac using UNetbootin.
- Plug a USB drive into your Mac and open Disk Utility. Select your USB drive from the left panel and click on Info button. Note down the device name since we will need that later.
- Next, download and launch the UNetbottin utility. Select the “Diskimage” radio button, click “…” to select a bootable ISO image.
- After locating your Windows 10 ISO file, click on Open.
- Choose Type as USB Drive and select the device name of your USB drive (you probably would’ve noted it down earlier, so refer to that). Click OK to start installing to the USB drive.
- This process takes several minutes or longer, depending on the size of your selected ISO image.
Method 2: Create Windows 10 Bootable USB on Mac Using Terminal
Of course, if you prefer not to use third-party software, you can still use the excellent Terminal app, which is a little bit more involved, but no additional software needs to be installed. Follow these steps:
- After connecting a USB drive to your Mac, open a Terminal window and type diskutil list to display all the disks attached to your machine. You have to figure out the disk identifier of the USB drive you need to format. In my example, my USB drive is mounted as “disk2” and it’s about 32GB.
- Next, run the following command to format your USB drive and name it “WIN10“, where # is a placeholder for the disk identifier of your USB drive.
diskutil eraseDisk MS-DOS 'WIN10' GPT disk#
- Now, mount your Windows 10 ISO image with the command below, assuming it’s saved the Downloads folder. In my case, it is mounted as a volume named “ESD-ISO“.
hdiutil mount ~/Downloads/your_windows_10_image.iso
- Finally, run the following command to copy all the files from the mounted ISO to your USB drive.
cp -rp /Volumes/ESD-ISO/* /Volumes/WIN10/
This command will take a while, and once it finishes, you can disconnect the mounted ISO with this command:hdiutil unmount /Volumes/ESD-ISO
- Now you should be able to boot from the USB to install Windows 10 on your Mac or Windows machine.
Conclusion
These should be the easiest ways to create a Windows 10 bootable USB from ISO on Mac, without using Boot Camp Assistant. No matter which method you prefer, be sure that you backup any important data on your USB drive, as the procedure of creating bootable USB will delete everything on it.
