In the Disk Utility app on your Mac, choose File > New Image > Blank Image.
Enter a filename for the disk image, add tags if necessary, then choose where to save it.
This is the name that appears in the Finder, where you save the disk image file before opening it.
In the Name field, enter the name for the disk image.
This is the name that appears on your desktop and in the Finder sidebar, after you open the disk image.
In the Size field, enter a size for the disk image.
Click the Format pop-up menu, then choose the format for the disk:
If the disk image will be used with a Mac that has a solid state drive (SSD) and uses macOS 10.13 or later, choose APFS or APFS (Case-sensitive).
If the disk image will be used with a Mac with macOS 10.12 or earlier, choose Mac OS Extended (Journaled) or Mac OS Extended (Case-sensitive, Journaled).
If the disk image will be used with a Mac or Windows computer and is 32 GB or less, choose MS-DOS (FAT); if it’s over 32 GB, choose ExFAT.
To encrypt the disk image, click the Encryption pop-up menu, then choose an encryption option.
Click the Partitions pop-up menu, then choose a partition layout.
Click the Image Format pop-up menu, then choose an option:
Sparse bundle disk image: Same as a sparse disk image (below), but the directory data for the image is stored differently. Uses the .sparsebundle file extension.
Sparse disk image: Creates an expandable file that shrinks and grows as needed. No additional space is used. Uses the .sparseimage file extension.
Read/write disk image: Allows you to add files to the disk image after it’s created. Uses the .dmg file extension.

Create a disk image from a disk or connected device
You can create a disk image that includes the data and free space on a physical disk or connected device, such as a USB device. For example, if a USB device or volume is 80 GB with 10 GB of data, the disk image will be 80 GB in size and include data and free space. You can then restore that disk image to another volume.
In the Disk Utility app on your Mac, select a disk, volume, or connected device in the sidebar.
Choose File > New Image, then choose “Image from [device name].”
Enter a filename for the disk image, add tags if necessary, then choose where to save it.
This is the name that appears in the Finder, where you save the disk image file before opening it.
Click the Format pop-up menu, then choose an option:
Read-only: The disk image can’t be written to, and is quicker to create and open.
Compressed: Compresses data, so the disk image is smaller than the original data. The disk image is read-only.
Read/write: Allows you to add files to the disk image after it’s created.
DVD/CD master: Can be used with third-party apps. It includes a copy of all sectors of the disk image, whether they’re used or not. When you use a master disk image to create other DVDs or CDs, all data is copied exactly.
To encrypt the disk image, click the Encryption pop-up menu, then choose an encryption option.
Click Save, then click Done.
Disk Utility creates the disk image file where you saved it in the Finder and mounts its disk icon on your desktop and in the Finder sidebar.
Important: Don’t create a disk image of a disk that you believe to be failing or that contains corrupted information. The disk image may not serve as a reliable backup.
For technical information about creating a restore disk image, see the Apple Software Restore (ASR) manual (man) page.
Create a disk image from a folder or connected device
You can create a disk image that contains the contents of a folder or connected device, such as a USB device. This method doesn’t copy a device’s free space to the disk image.

In the Disk Utility app on your Mac, choose File > New Image, then choose Image from Folder.
Select the folder or connected device in the dialog that appears, then click Open.
Enter a filename for the disk image, add tags if necessary, then choose where to save it.

Compressed: Compresses data, so the disk image is smaller than the original data. The disk image is read-only.
Read/write: Allows you to add files to the disk image after it’s created.
DVD/CD master: Can be used with third-party apps. It includes a copy of all sectors of the disk image, whether they’re used or not. When you use a master disk image to create other DVDs or CDs, all data is copied exactly.
Hybrid image (HFS+/ISO/UDF): This disk image is a combination of disk image formats and can be used with different file system standards, such as HFS, ISO, and UDF.

Create a secure disk image
What Is A Dmg File Type
If you have confidential documents that you don’t want others to see without your permission, you can put them in an encrypted disk image.
Note: If you want to protect the contents of the system disk, turn on FileVault using the FileVault pane of Security & Privacy Preferences.
In the Disk Utility app on your Mac, choose File > New Image > Blank Image.
Enter a filename for the disk image, add tags if necessary, then choose where to save it.
This is the name that appears in the Finder, where you save the disk image file before opening it.
In the Name field, enter the name for the disk image.
This is the name that appears on your desktop and in the Finder sidebar, after you open the disk image.

If you’re using the encrypted disk image with a Mac computer using macOS 10.13 or later, choose APFS or APFS (Case-sensitive).
If you’re using the encrypted disk image with a Mac computer using macOS 10.12 or earlier, choose Mac OS Extended (Journaled) or Mac OS Extended (Case-sensitive, Journaled).
Click the Encryption pop-up menu, then choose an encryption option.
Enter and re-enter a password to unlock the disk image, then click Choose.
WARNING: If you forget this password, you won’t be able to open the disk image and view any of the files.
Use the default settings for the rest of the options:
Click the Partitions pop-up menu, then choose Single partition - GUID Partition Map.
Click the Image Format pop-up menu, then choose “read/write” disk image.
Click Save, then click Done.
Disk Utility creates the disk image file where you saved it in the Finder and mounts its disk icon on your desktop and in the Finder sidebar.
In the Finder , copy the documents you want to protect to the disk image.
If you want to erase the original documents so they can’t be recovered, drag them to the Trash, then choose Finder > Empty Trash.
When you’re finished using the documents on the secure disk image, be sure to eject the disk image. As long as it’s available on your desktop, anyone with access to your computer can use the documents on it.
To access the data in a disk image, double-click it. It appears on your desktop, and you can add, remove, and edit files on it just as you would with a disk.
With so many privacy threats around, having an extra layer of protection on your Mac is crucial. Luckily, you can keep your private data far from prying eyes by putting it in a password-locked folder.
Let’s see how to password protect a folder on Mac so that no person or app could crack it.
Why you might want to protect a folder with a password
You wouldn’t show your credit card statements in public. So why not protect financial or health information on your computer? If you share your Mac with someone else, password protection will cover up files that you don’t want anyone to see. That also keeps your private data private if you lose your device.
Even if you’re the only user of your Mac, locking and encrypting your sensitive files is a must these days. Did you know that some data-mining apps could spy on your documents and folders? As cybercriminals adopt new tactics and code innovations, there’s no telling if your computer is hacked, until your bank account turns out to be empty.

Putting Files In Locked Dmg Download
To be on the safe side, savvy Mac users regularly check their computers with anti-malware software. My personal favorite is CleanMyMac X, as Apple notarized it on macOS Catalina. It comes with a Malware Removal tool that deals with Mac-specific viruses. Here is how it works:
- Launch the app (get a free version here).
- Choose the Malware Removal tab in the sidebar.
- Click Scan.
- If CleanMyMac X detects a threat, press Remove to get rid of it. If it doesn’t, congratulations! You have no malware on your Mac.
How to password lock a folder on Mac
With Disk Utility, which is available on every Mac, you can encrypt and password protect a folder by turning it into a disk image (DMG). Follow the steps below:
- Open Finder > Applications > Utilities > Disk Utility.
- Go to the File menu > New Image > Image from Folder.
- Select a folder you want to password protect in the dialog box that appears, then click Choose.
- Enter a filename for the disk image and select where to save it.
- Pick a preferred encryption option from the dropdown menu: 128-bit AES encryption (recommended) or 256-bit AES encryption (more secure, but slower).
- Enter and verify your password in a new dialog box. Tap the key icon to open Password Assistant and check how secure your password is. Once you’re done with a password, click Choose.
- Click the Image Format menu and pick ‘read/write’.
- Click Save, then click Done. Now your folder is password-protected.
There is no way to recover the password to password-protected DMG file, so choose the one you won’t forget or write it down in a safe place.
Note that the original folder is still on your Mac. Make sure you have no issues accessing the DMG file, then trash the original folder so that no one gets access to it.
How to lock a folder on Mac without Disk Utility? You can do that with Terminal or third-party apps with similar functionality. Still, I opt for Disk Utility, as this method is relatively fast.
CleanMyMac X’s Privacy tool gathers all your Mac’s private data in one place. With its help, you can clean up your online and offline history, including chat transcripts, browsing traces, Recent Items lists, and even old Wi-Fi networks.
Run Dmg File On Mac
How to use a password-protected folder
Go to the location where you saved the disk image and double-click to open and mount it to your Mac. Enter the password when prompted and press OK. You can optionally check the box to save the password in your keychain.
Once you enter the password, the DMG file mounts in two places: on your desktop and in the Finder sidebar. Click either one of these to open the folder.
To password protect it again, click the eject icon in the Finder sidebar. That’s it!
Hope this step-by-step guide will help you keep your sensitive files safe and private.
