How to Burn ISO Files to DVD

On Mac

1. 
   Insert a blank DVD into your Mac's CD slot. Since most Macs don't come with a built-in disc slot, you will likely need an external DVD reader to do this.

   1. You can buy an external disk reader from Apple for less than $90.
   2. To attach an external DVD reader to your Mac, connect the DVD reader's cable to your Mac's USB port (on the left side of a Mac laptop or on the back of an iMac desktop monitor).
2. 
   Make sure you know where your ISO file is. The burning process is simplest when the ISO file is somewhere easy to access, such as your Mac's desktop.
3. 
   Open Spotlight

   

   . Click the magnifying glass icon in the top-right corner of the screen. A search bar will appear.
4. 
   Type disk utility into Spotlight. This will search your Mac for the Disk Utility app, which is what you'll use to burn the ISO file.
5. 
   Click Disk Utility. It's a grey hard drive icon with a stethoscope on top of it. You should see it at the top of the Spotlight search results.
6. 
   Click Burn. This radioactive symbol-shaped icon is at the top of the window. A pop-up Finder window will appear.
7. 
   Select your ISO file. Click on the ISO file's location folder (e.g., Desktop) on the left side of the Finder window, then click the ISO file to select it.
8. 
   Click Burn. It's in the bottom-right corner of the window. This will close the Finder window.
9. 
   Click Burn when prompted. This option is in the drop-down window at the top of the Disk Utility window. Clicking it prompts the burning process to begin.

   1. Depending on the size of the ISO, burning can take anywhere from a few minutes to a few hours.
10. 
    Click OK when prompted. You'll see this in the lower-right corner of the completion window. Doing so concludes the burn process.
