  • A USB flash drive or other secondary volume formatted as Mac OS Extended, with at least 14GB of available storage
  • A downloaded installer for macOS Big Sur, Catalina, Mojave, High Sierra, or El Capitan

Download macOS

  • Download: macOS Big Sur, macOS Catalina, macOS Mojave, or macOS High Sierra
    These download to your Applications folder as an app named Install macOS [version name]. If the installer opens after downloading, quit it without continuing installation. To get the correct installer, download from a Mac that is using macOS Sierra 10.12.5 or later, or El Capitan 10.11.6. Enterprise administrators, please download from Apple, not a locally hosted software-update server.
  • Download: OS X El Capitan
    This downloads as a disk image named InstallMacOSX.dmg. On a Mac that is compatible with El Capitan, open the disk image and run the installer within, named InstallMacOSX.pkg. It installs an app named Install OS X El Capitan into your Applications folder. You will create the bootable installer from this app, not from the disk image or .pkg installer.

Use the 'createinstallmedia' command in Terminal

  1. Connect the USB flash drive or other volume that you're using for the bootable installer.
  2. Open Terminal, which is in the Utilities folder of your Applications folder.
  3. Type or paste one of the following commands in Terminal. These assume that the installer is in your Applications folder, and MyVolume is the name of the USB flash drive or other volume you're using. If it has a different name, replace MyVolume in these commands with the name of your volume.

Big Sur:*

Catalina:*

Mojave:*

High Sierra:*

Mac

El Capitan:

* If your Mac is using macOS Sierra or earlier, include the --applicationpath argument and installer path, similar to the way this is done in the command for El Capitan.

A bootable installer doesn't download macOS from the internet, but it does require an internet connection to get firmware and other information specific to the Mac model.

For information about the createinstallmedia command and the arguments you can use with it, make sure that the macOS installer is in your Applications folder, then enter the appropriate path in Terminal:

A .DMG file is a container file commonly used to distribute applications for Mac OS X. Installing software from one of these requires you to mount the image and move its contents to your computer’s “Applications” directory.

One of the most common mistakes I see among new Mac users is fumbling with how to install and open .dmg files or new software. The process for installing new applications on your Mac can be confusing at first because it differs greatly from Windows’ software installation process. Nevertheless, the Mac method of installing software is actually quite simple and intuitive once you are accustomed to it. If your desktop is littered with DMG files and white “drive”-looking icons, read on!

What are .DMG Files?

DMG stands for Disk Image, and is a format commonly used to distribute files and applications among Apple computers. A DMG file is like a virtual DVD or hard drive. They can be “mounted” on your Mac in order to work with their contents, or even burned to an actual physical disc.

In order to understand the concept of a DMG disk image, think of a storage volume such as a CD, DVD, hard drive, or external drive. A DMG file is like one of these devices in that it serves as a means to encapsulate documents, images, software, and other files. The difference is that with a DMG, there is no physical storage medium. There is only the DMG file, which can be written to a hard drive, burned to a CD or DVD, or sent over the Internet.

In order to work with the contents of a DMG file, you must mount the the disk image to your system. This may sound daunting, however “mounting” a DMG file with Mac OS X is no more complicated than double-clicking it’ icon. The operating system will load the load image and place a new icon both on your desktop, and in the sidebar of the Finder. The icon will have the same name as the DMG, and you’ll be able to browse through its contents like any other folder.

Once you are done working with the contents of the file, you will want to remove or “unmount” it from your system. Do this by opening the Finder and clicking the eject icon next to the virtual drive’s icon. Or, go to the Desktop, click once on the icon, and press CMD+E.

How to Install and Open .dmg Files on a Mac

Software installation with Mac OS X is very different than in the Windows world. On a Windows PC you run an installer, tick off a few checkboxes, and wait for the progress meter to reach completion. There usually is no such “installation wizard” on a Mac &emdash; you simply drag and drop the program into your computer’s “Applications” directory. The trick is that most Mac applications are distributed as images called DMG files, and many new Mac users end up running applications directly from the image instead of installing them to the “Applications” directory.

Enough explanation, here’s how to install an OS X app from a DMG file:

  1. Find the downloaded file, which usually ends up in your Desktop or Downloads folder.
  2. Double-click the .DMG file to mount it. A new Finder window showing its contents should appear.
  3. If the window also contains a shortcut icon to “Applications”, drag and drop the app onto the shortcut.
  4. If not, double-click the mounted volume on your desktop and drag the app icon from there to the “Applications” icon in the Finder sidebar.

Further Explanation

Alright, that was the abridged version. Here’s the long version. I’ve just downloaded the DeskLickr application, and the DeskLickr_1.2.dmg is sitting on my desktop. I double-click it and a new icon labeled “DeskLickr 1.2” appears on my desktop. Here’s what my desktop looks like at this point:

Since most of the time a new Finder window also pops up when the image is ready for use, this one is now sitting on my desktop:

Different applications are going to show you slightly different Finder windows. Each application’s designers like to add their own artwork. Glitter aside, most applications are trying to tell you the same thing. See the arrow pointing from the DeskLickr icon to the “Applications’ shortcut? It’s telling you to drag and drop the icon into that folder. Once you’ve done so, the app will be installed.

If a program doesn’t provide a shortcut to the Applications folder, you’ll need to pop open a new Finder window. Press CMD+N to open a new window, then drag the program over to “Applications” in the left-hand side of the window.

House Cleaning

Once the new program is installed it’s time to do some house cleaning. You no longer need the disk image you downloaded, so follow these steps:

Installing Dmg On Mac From Terminal

  2. Eject the disk image (not the .DMG file). Click on its desktop icon, then press CMD+E.
  3. Delete the .DMG file by dragging it to the trash.

That’s it! Your new Mac application is ready to use. But wait…
