Making a Bootable USB from ISO on Mac OSX. Posted on 2015/06/13. Been doing tons of writing images to USB recently and have found these few commands very useful. To do this we first need a ISO image we want to write to USB. In our case this would be the latest Ubuntu release I grabbed. Method #1: Create Bootable USB/DVD on Mac Using Disk Utility.

But before you do anything else, a word of caution: once you've used the OS X installer, it will automatically delete the file you need to make the backup disk, so you'll want to either make a copy of the installer or create your disk before you upgrade. You can use a USB flash drive, external hard drive, or DVD-R disc, but the USB drive is quicker. If you're using a USB drive, it has to be formatted as 'Mac OS Extended (Journaled)' and set to partition type 'GUID Partition Table' in order to work.

This is the image file that contains the information you need to create the backup disk. Step 2: Open Disk Utility (located in your Applications > Utilities folder). Step 3: Drag and drop the ' InstallESD.dmg' into the list of drives on the left and select it. This should make it appear in the Source box on the right. If not, you may have to click the ' Restore' tab as seen below.
