Mac OS X 10.11 El Capitan ISO: Click to Download.
- Also, the converted file may have an additional.dmg extension added to it by Mac OS X. Don’t worry, it’s normal. Step 4: Get the device number for USB drive The next thing is to get the device number for the USB drive.
If you’re still using a Mac OS X the time will come when your computer won’t boot, or a problem may arise where you can’t take control of the device, and booting from an OS X installation media will be required.
This is why it’s recommended that you make a Mac OS X bootable USB when your Mac is in working conditions. However, if you find yourself on a scenario where your device (iMac, MacBook Pro, Air, Mac Pro or Mini) is not responding and you happen to have a Windows 10 device, then you can still be able to make a USB bootable installation media for your Mac OS X to reinstall the operating system using the Recovery Assistant.
These instructions will also work for Windows users who are running Mac OS X on a virtual machine and need to upgrade to the latest version. For instance, to OS X Yosemite.
Requirements
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).
Now that you have all the necessary ingredients, you’re ready to make a Mac OS X bootable USB using the DMG file of the operating system with the steps below.
Create Mac OS X bootable USB installation media
Before you can use TransMac, you 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 10.
Setting up GPT partition
Use these steps to set up a USB drive with a GPT partition:
Open Start on Windows 10.
Search for Command Prompt, right-click the top result and select the Run as Administrator option.
Type the following command to open Diskpart and press Enter:
Type the following command to determine the USB flash drive and press Enter:
Type the following command to select the storage and press Enter:
Quick tip: Theselect disk 1command as an example, but you have to replace 1 with the number of the flash drive you want to use.Type the following commands to delete everything from the USB thumb drive and press Enter:
Type the following command to convert the drive into a GPT partition and press Enter:
Type the following command to select the new partition and press Enter:
After you complete the steps, the USB flash drive from MBR to GPT format, you can use the steps below to create a bootable USB installation media to install Mac OS X.
Create USB install media
Use these steps to create a bootable media to install Mac OS X:
Download and install a copy of TransMac.
Quick note: 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 the Run option.)
On the left pane, you’ll see all the Windows PC drives listed, right-click the USB drive that you’re intending to use to reinstall Apple’s OS X and select the Restore with Disk Image option.
In the warning dialog box, click the Yes button.
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 the OK button 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.
If you’re having issues trying to create a bootable media, you can get a USB flash drive that comes with Mac OSX ready to install.
Looking for the best ISO to USB burner for Mac? It's possible, but ISO is not native file type in Mac OS X or macOS environment, so you need to use workaround methods or employ a third-party ISO burning utility for Mac to get this done. This article covers three ways to burn ISO to USB stick on a Mac computer, powered by macOS Catalina, Mojave, High Serria and earier Mac OS X systems.
The first thing you need to know is that you can't use an ISO disk image file on a Mac, since Apple primarily uses the DMG format. However, if you merely want to burn ISO to a USB stick, that's definitely possible. The only thing you can't do is run an ISO file on an Apple computer. Let's look at the various ways to burn ISO to USB on a Mac machine.
[Notice]: There are different types of ISO images (Windows, Linux, Raspbian OS, etc.) and they apply different booting schemes. So basically, there is not a perfect software out there that can burn all ISO images successfully. You should try another suggestion if one failed.
[Update 1]: If you have any question during ISO burning process, please check out the FAQ Part at the end of this article.
[Update 2]: New version of UUByte ISO Editor for Mac now supports large Windows 10 ISO image (over 5GB) and macOS Big Sur.
Part 1: How to Burn ISO to USB on Mac with Terminal Software
Terminal is Apple's command line equivalent of Command Prompt in Windows and Terminal in Linux. Using this command line utility, you can burn an ISO file to an external DVD or USB disk. If you did not t have any experience with text command, then this is not recommended because it is too risky to damage the local disk with wrong input. Terminal allows you to do several system-level operations, so don't input anything other than the commands specified in the process outline shown below:
Step 1: Click Terminal icon from the Dock. Or Go to the Applications folder on Mac and find the Terminal app in Utilities folder.
Step 2: Copy the ISO file in a convenient location so your command doesn't have to be too long. Saving it to desktop or downloads folder is usually a good idea. Make sure you remember the name of the ISO file because it will be used in the command.
Step 3: If your ISO file is in your Desktop, then run the following command (press Enter after typing the command): cd desktop
Step 4: Now run the following command (hit Enter after typing): hdiutil burn filename.iso
Step 5: Once you run the command, your ISO file will be burned to the USB drive in your default optical drive. If you haven't inserted a disk, you will be prompted to do so. There is no need to run the command again after inserting the USB.
Cons:
- Dangerous and not safe for beginners.
- Sharp learning curve.
- Bad support for USB 2.0 device.
- Lower success rate.
If you want to avoid any kind of command line work and if you're running one of the newer versions of macOS, then it's better to use a third-party software like the one described in Part 2 below.

Part 4: Frequently Asked Questions
How To Burn Mac Dmg To Usb In Windows
Q: Why file copying process failed?
The USB will be formatted to FAT32 in order to create a working Windows partition on Mac. This means you can not copy a file larger than 4GB. This is one of the biggest issue with FAT32 file system. We noticed that the latest Windows 10 ISO downloaded from Microsoft.com will over 5GB and the install.wim file is obviously larger than 4GB. That's why file copying process faile during burning process. The solution is to download an old version of Windows 10 from other sources.
Q: Why my USB drive is not bootable by using hdiutil command?
It is a common case for Windows ISO image because this command does not write Windows bootloader to USB drive. You have to format the drive to FAT32 first in Disk Utility.
Q: Can not select USB drive in UUByte ISO Editor?
If the USB drive could be recognized by Mac but not in UUByte ISO Editor, then it is highly possible that your Mac is in Dark Mode. To fix this, please switch to Light mode instead.
Q: Should I format USB stick to NTFS?
No. Mac can only see USB drive formatted with exFAT or MS-FAT. NTFS is not supported by Mac in default. So you can not write ISO image to NTFS USB on Mac. FAT32 is more recommended!
