Create Bootable Yosemite USB from DMG

In this article, we will guide you on how to create a bootable Yosemite USB installation media using a Windows 10 computer and a DMG file containing the macOS installation files.

To begin with, you will need a high-quality USB flash drive with at least 16GB of storage. Make sure that the drive is not already formatted with an MBR partition, as this may cause issues when trying to use it on a Mac.

The first step is to create a GPT partition on the USB flash drive using the Diskpart command-line utility on Windows 10. This will ensure that the drive is compatible with macOS.

Once you have created the GPT partition, download and install TransMac on your Windows 10 computer. This software will allow you to restore the DMG file onto the USB flash drive.

To begin the restoration process, right-click on the USB flash drive and select the 'Restore with Disk Image' option from the left pane. Confirm that you want to erase all data on the drive by clicking the Yes button.

Next, click the Yes button again to format the drive on the warning message. Finally, confirm a name for the drive and wait for the restoration process to complete.

Once the restoration is complete, you can insert the USB flash drive into your Mac computer and use it to install, reinstall, or upgrade the operating system to the latest macOS version (Ventura, Monterey, Big Sur, Catalina, or Sierra).

In summary, creating a bootable Yosemite USB installation media using a Windows 10 computer and a DMG file is a straightforward process that requires a few simple steps. By following this guide, you can create a reliable and functional bootable USB drive that will allow you to install, reinstall, or upgrade your Mac operating system with ease.
