Reader Forrest Bourke seems lost in the woods in regard to making disk images compatible with Windows. He writes: How do I make an ISO image? Hybrid image (HFS+/ISO/UDF): This disk image is a combination of disk image formats and can be used with different file system standards, such as HFS, ISO, and UDF. Click Save, then click Done. Disk Utility creates the disk image file where you saved it in the Finder and mounts its disk icon on your desktop and in the Finder sidebar.

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 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 it to a disk, 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.

Part 1: How to Burn ISO to USB With Mac 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.
• USB not bootable.

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.
