Understanding the Process
Before we dive into the steps, let’s understand the fundamentals. We’ll be using a tool called TransMac, which allows us to work with Mac disk images (DMG files) on a Windows machine. This tool enables us to create a bootable USB drive with the Yosemite installer, making it possible to boot your Mac from the USB drive.
Gathering the Necessary Tools
To create a bootable USB drive for Mac OS X Yosemite from Windows, you’ll need the following:
- A Mac OS X Yosemite installer DMG file: This file can be downloaded from the Mac App Store or from a reliable source online.
- A USB drive: Ensure it has at least 8 GB of free space. Format it to FAT32 using your Windows computer before proceeding.
- TransMac: This software is available for purchase from the TransMac website. A trial version is also available, which allows you to test the software before committing to a purchase.
Step-by-Step Guide
Now, let’s get started with creating your bootable USB drive:
1. Download and Install TransMac: Download the TransMac software from the official website and install it on your Windows computer.

3. Mount the Yosemite Installer DMG: Locate the Yosemite installer DMG file on your computer. Drag and drop the DMG file onto the TransMac window. TransMac will mount the DMG file, making its contents accessible.
4. Create a Bootable USB Drive: Right-click on the USB drive in TransMac and select “Restore with Disk Image.” In the pop-up window, select the Yosemite installer DMG file from the list of available disk images. Click “Restore.”
5. Wait for the Process to Complete: TransMac will begin copying the Yosemite installer files to your USB drive. This process can take some time, so be patient.
6. Eject the USB Drive: Once the process is complete, you’ll receive a notification. Safely eject the USB drive from your computer.
Boot Your Mac from the USB Drive
With the bootable USB drive created, you can now boot your Mac from it. Follow these steps:
1. Restart Your Mac: Turn off your Mac and restart it.
2. Hold Down the Option Key: As your Mac starts up, hold down the **Option** key.
3. Select the USB Drive: A list of bootable devices will appear. Select the USB drive with the Yosemite installer and press **Enter**.
4. Follow the On-Screen Instructions: The Mac OS X Yosemite installer will launch. Follow the on-screen instructions to install or reinstall Yosemite on your Mac.
