How to Create a Mac OS ISO to USB Bootable Drive

In this day and age, having the ability to create a bootable USB drive for your Mac OS installation is an essential step in installing the operating system on your computer. With the rise of USB sticks as a primary means of installing software, it's becoming increasingly important to know how to convert an ISO image into a format that can be written directly onto a USB stick.

Fortunately, Mac OS provides all the necessary tools to accomplish this task with ease. The key is to understand that the file extension of the image won't affect its format, thanks to the hdiutil program which automatically adds the `.dmg` file extension.

To begin, you'll need to convert the ISO image into a UDRW (Read/Write Universal Disk Image Format) using the following command:

`hdiutil convert -format UDRW -o destination_file.img source_file.iso`

This command will create a new image file in the format of your choice, which can then be written onto a USB stick.

The reason why we need to use the UDRW format is that it includes all the necessary files to boot your PC or server. The ISO file you downloaded contains an image of the entire media, including all the installation files and setup tools.

Once you have converted the ISO image into a UDRW format, you can simply copy the resulting image onto the USB stick using your preferred method.

In conclusion, creating a Mac OS ISO to USB bootable drive is a relatively simple process that requires minimal technical expertise. With the right tools and a basic understanding of how to use them, you'll be able to create a bootable USB drive in no time. This method not only provides a convenient way to install your operating system, but it's also more cost-effective than burning a CD or DVD that may become outdated quickly.

Additionally, creating a bootable USB stick is an essential step in today's computing world where many PCs and servers are delivered without a CD/DVD drive. With the rise of Linux distributions offering ISO images for free download, the need to create a bootable USB stick has become more important than ever.

In summary, converting an ISO image into a UDRW format and writing it onto a USB stick is a straightforward process that can be completed using your Mac OS terminal. With this guide, you'll be able to create a bootable USB drive for your Mac OS installation in no time.
