To build a disk image from a disk or a linked device, use the Disk Utility in macOS. A file called a disk image (.dmg file) has the appearance and functionality of a mountable device or volume.

Why should you worry about disk images?

Disk images can be made from your hard drive or a USB flash drive, although they are often copies of specific optical media. There are several benefits to adopting them, including the following, according to Faronics, a firm that "delivers software that helps manage, simplify, and protect multi-user computer settings."

You don't have to configure each computer separately or install the entire operating system from the start because you can duplicate one system to several identical machines. Multiple Macs can display the same image.

Since you can create as many distinct images as you desire, they are practical for incremental backups.

Files are created from images. You don't have to keep the actual hardware around if you only want or need to preserve the data from a Mac. Simply build and store an image of that drive.

Disk image creation on M2-Chip Mac

You may build a disk image that holds the information and empty space on a physical disk or attached device, such as a USB device, using the Mac's Disk Utility, which can be found in the Utility folder inside the Applications folder on your Mac's hard drive. The disk image will be 80 GB in size and contain both data and free space. For instance, if a USB device or volume is 80GB in size and contains 10GB of data. The disk image can then be restored to another volume.

This is how:

  • Data is squeezed, resulting in a disk image that is smaller than the original data. There is a read-only disk image.
  • After creating a disk image, you may add files to it using read/write access.
  • DVD/CD master: Compatible with outside applications. Regardless of whether they are used or not, it contains a duplicate of every sector on the disk image. All data is precisely replicated when you make additional DVDs or CDs using a master disk image.
  • Click the Encryption pop-up menu, then select an encryption option to encrypt the disk image.
  • After selecting Save, click Done.

Disk Utility mounts its disk icon on your desktop and in the Finder sidebar and produces the disk image file where you placed it in the Finder.
