As a Mac user, you may have encountered situations where you need to access a disk image (also known as a .dmg file) to install software, update your operating system, or troubleshoot issues with your computer. But, where exactly do you find these mysterious files on your Mac? In this article, we’ll delve into the world of disk images and explore the various locations where you can find them on your Mac.
What are Disk Images?
Before we dive into the process of finding disk images, let’s take a step back and understand what they are. A disk image is a digital replica of a physical disk, such as a CD, DVD, or USB drive. It’s a single file that contains the entire contents of the original disk, including files, folders, and even the disk’s structure. Disk images are commonly used to distribute software, operating systems, and other digital content.
Disk images can be created using various tools, including Apple’s built-in Disk Utility app. They can also be mounted on your Mac, allowing you to access the contents of the image as if it were a physical disk.
Where to Find Disk Images on Mac
Now that we know what disk images are, let’s explore the various locations where you can find them on your Mac.
Downloads Folder
One of the most common places to find disk images is in your Downloads folder. When you download a software installer or a disk image from the internet, it’s often saved to this folder by default. To access your Downloads folder, follow these steps:
- Click on the Finder icon in the Dock to open a new Finder window.
- Click on the “Downloads” folder in the sidebar.
- Scroll through the list of files and folders to find the disk image you’re looking for.
Desktop
Another common location for disk images is on your Desktop. If you’ve downloaded a disk image and saved it to your Desktop, you can find it there. Simply click on the Desktop icon in the Finder sidebar or navigate to your Desktop using the finder window.
Applications Folder
Some disk images may be stored in the Applications folder, especially if they’re related to software installers. To access the Applications folder, follow these steps:
- Click on the Finder icon in the Dock to open a new Finder window.

- Click on the Applications/Utilities folder in the Finder sidebar.
- Double-click on the “Disk Utility” app to open it.

Other Folders and Locations
In some cases, disk images may be stored in other folders or locations on your Mac, such as the Documents folder, the Pictures folder, or even an external hard drive. If you’re unable to find the disk image in the above locations, try searching for it using Spotlight or checking your other folders and devices.
Tips for Working with Disk Images

What are disk images on a Mac?
Disk images are virtual replicas of physical disks or folders that contain a collection of files and data. They are essentially a single file that contains all the data from a physical disk, such as a CD, DVD, or hard drive. Disk images can be used to store and distribute large files, create backups, and even install operating systems.
Disk images are commonly used on Macs to create bootable installers for macOS, distribute software, and store large files. They can be mounted on a Mac just like a physical disk, allowing users to access the contents of the image as if it were a real disk. Disk images can be created using the Disk Utility app on a Mac, or using third-party software.
Where are disk images usually stored on a Mac?
Disk images are not stored in a specific location on a Mac by default. When you download a disk image, it is usually saved to the Downloads folder, but you can store it anywhere on your computer. However, it’s a good idea to keep your disk images organized by storing them in a specific folder, such as a “Disk Images” or “Downloads” folder.
You can also store disk images on an external hard drive or cloud storage service, such as iCloud or Google Drive. This can be useful if you need to access the disk image from multiple devices or want to free up space on your Mac’s internal hard drive.
How do I create a disk image on a Mac?
To create a disk image on a Mac, you’ll need to use the Disk Utility app. You can find Disk Utility in the Applications/Utilities folder, or use Spotlight to search for it. Once you’ve opened Disk Utility, select “File” > “New Image” > “Blank Image” and choose the size and type of disk image you want to create.
You can then add files and data to the disk image by dragging and dropping them into the Disk Utility window. Once you’ve added all the files you want, select “File” > “Save” to save the disk image to your Mac. You can also use third-party software to create disk images, such as ETCH or DiskMaker X.
How do I mount a disk image on a Mac?
To mount a disk image on a Mac, simply double-click the disk image file (.dmg, .iso, or .img). The disk image will then be mounted on your Mac, and you’ll be able to access the contents of the image as if it were a real disk. You can also use Disk Utility to mount a disk image by selecting “File” > “Open” and choosing the disk image file.
Once the disk image is mounted, you can access the contents of the image by clicking on the disk image icon on your desktop or in the Finder. You can then copy files from the disk image to your Mac, or run software installers from the image.
How do I burn a disk image to a physical disk on a Mac?
To burn a disk image to a physical disk on a Mac, you’ll need a blank DVD or CD, and a disk burner such as the SuperDrive. You can then use Disk Utility to burn the disk image to the physical disk. Select “File” > “Open” and choose the disk image file, then select “Burn” and choose the physical disk as the destination.
Follow the on-screen instructions to complete the burning process. You can also use third-party software, such as Roxio Toast, to burn disk images to physical disks.
Can I delete a disk image after mounting it on a Mac?
Yes, you can delete a disk image after mounting it on a Mac. However, you’ll need to unmount the disk image first by dragging the disk image icon to the Trash or by right-clicking (or control-clicking) on the disk image icon and selecting “Eject”. Once the disk image is unmounted, you can delete the disk image file by moving it to the Trash and emptying the Trash.
Be careful when deleting disk images, as they may contain important data or software installers that you need to keep. Make sure you have a backup of the disk image or its contents before deleting it.
Can I use disk images on other devices, such as PCs or mobile devices?
Disk images are specific to Macs and cannot be used directly on PCs or mobile devices. However, you can convert disk images to other formats, such as ISO files, that can be used on PCs or other devices. You can use third-party software, such as ETCH or DiskMaker X, to convert disk images to other formats.
You can also use cloud storage services, such as iCloud or Google Drive, to store disk images and access them from other devices with an internet connection. However, you’ll need to ensure that the device you’re using has the necessary software to mount and access the disk image.
