How to Create a DMG Disk Image on My Mac

Creating a DMG disk image on Mac has become a very useful function for those who want to have a new device to store information.

The DMG format is probably one of the most widely used extensions among Apple computers. Especially when applied to a removable drive like a CD. Since it allows the data to be copied, deleted or modified after carrying out the conversion.

For the benefit of all, through the systems that the computers operate, this style of tools can be created. But in addition, there are third-party programs that help facilitate this process.

When it comes to Mac computers, they also have a quality that allows them to create this type of disk image in DMG format. So that your users can take advantage of its features.

That is why in the following article we will talk a little about how you can use a CD to generate a removable storage device and the ways to create it through a Mac.

With what software can you create a DMG disk image to store files?

The operating system designed by the Apple company is currently in high demand, due to its high level of security and usefulness when performing some type of task.

As mentioned previously, there is the possibility of using any disk without information and transforming it into a storage medium , which will operate in the same way as a pendrive: removable and with absolute manipulation of its files.

But to achieve this, it must first be designed within a computer, a task that is quite simple within a Mac, since it has “Disk Utility” . This program is the one that will allow you to create the DMG disk image.

Steps to create a disc image from a CD

The “Disk Utility” program allows you to create a varied classification of disk images, based on the possible needs that the user faces when using it.

Among them, there is the possibility of inserting a CD into the computer and using its storage space as a memory base for the DMG disk image .

In this way, the removable disk will be configured in the way you want, and in turn uses the disk’s memory in its entirety to save files.

Starting to configure the disk image

Once you have inserted the CD into your computer, you can begin the procedure to create the image file. To do this, look through the library of “Disk Utility” programs, or remember that you can use “Finder” to find it quickly .

When you open the program, the sidebar of the home screen will allow you to choose between the disks that are currently connected to the computer. Select the one you will use.

At the top is the toolbar, which has a “File” tab that you must click to choose “New Image” and ” Image from X” .

Said “X” refers to the CD that you have inserted into the computer and previously selected to convert to a DMG disk image .

Set the details for the disc in question

Mainly, choose a filename for the image you are going to create. This will be visible every time the CD is inserted into a computer.

Mac computers have a characteristic when they make this type of creations, since they generate a backup within the computer . Based on which they will open the file folder each time it needs to be used. Therefore, the second detail tries to establish the address, where said backup will be saved within the PC system.

Within the “Format” section comes the essential aspect within this creation. Since that is where it is stated that you want to create a DMG disk image. Carrying out it is very simple, just drop down the menu and select the desired extension.

Finally, and only if necessary, you also have the option of encrypting the disk to give it greater security . You will finish by pressing the save button and selecting “OK”. Creating a DMG disk image on Mac has never been easier! You can have a new storage tool fully available to you.
