Things to know before proceeding
Before you dive into this guide, you’ll need a few things:
- A broken Mac computer with Mac OS X.
- A trial copy of the TransMac software.
- One high quality USB flash drive with 16GB of storage.
- A copy of Apple’s macOS (DMG file).

How to create Mac OS X bootable USB installation media
Before you can use TransMac, you may first need to partition your USB flash drive with a GPT partition, as a normal MBR partition may not work. To do this, you’ll need to use the Diskpart command-line utility on Windows.
Setting up GPT partition
To set up a USB drive with a GPT partition, use these steps:
- Open Command Prompt with administrative permissions.
- Type the
diskpart
command and press Enter. - Type the
list disk
command to view a listing of drives connected to your computer and press Enter. - Type the
select disk
command followed the number assigned for the USB flash drive (e.g.,select disk 4
), and press Enter. - Type the
clean
command and press Enter. - Fusion 360 custom tool for mac. Type the

command and press Enter to complete the task.

Creating USB install media
To create a bootable media to install Mac OS X, use these steps:
- Download and install a copy of TransMac, which is the software that will make everything happen. TransMac is a paid software, but it has a 15-day trial solution, that give us more than enough time to move the DMG files to the USB drive from Windows. (If you want to support the developer, you can purchase the full version.)
- Insert the USB drive that you’ll use to fix your installation of OS X. Remember that all the data in the USB will be erased. Make sure you take off any important documents.
- Right-click the TransMac software icon and Run as administrator. You’ll be prompted to Enter Key or Run, because we’ll be using it once, click Run.
- On the left pane, you’ll see all the Windows PC drives listed, right-click the USB drive you’re intending to use to reinstall Apple’s OS X and click Restore with Disk Image.
- In the warning dialog box, click Yes.
- Use the Restore Disk Image to Drive dialog box to browse for the DMG file with the installation files for Mac OS X Yosemite in this case, and click OK to create a bootable USB of the operating system.Now, you’ll have to wait a long time. No kidding. It could take one or two hours to complete the process depending on your computer and other variables.
Once your bootable USB installation media is ready, remove it and insert it into your Mac, power it on, holding down the Option key, and select the USB you just created to reinstall Mac OS X.
