These advanced steps are primarily for system administrators and others who are familiar with the command line. You don't need a bootable installer to install macOS, but it can be useful when you want to install on multiple computers without downloading the installer each time.

DMG file is a compressed file format being used widely on Mac computer. Windows OS doesn't natively support DMG disk image files, so if you need to create a bootable USB drive from a DMG file, mostly for bootable Mac OS X or macOS installation USB, you need a special utility to help you complete the task.

Download a macOS installer.* You can find the appropriate download link in the upgrade instructions for macOS Catalina, macOS Mojave, macOS High Sierra, macOS Sierra, and OS X El Capitan.
- If the macOS installer opens after downloading, quit it without continuing installation.
- macOS Sierra and El Capitan download as a disk image that contains an installer named InstallOS.pkg or InstallMacOSX.pkg. Run this installer before continuing.
- If downloading macOS Catalina, macOS Mojave, or macOS High Sierra for the purpose of creating a bootable installer, your Mac must be 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.
Then find the installer in your Applications folder as a single ”Install” file, such as Install macOS Catalina.
Use the 'createinstallmedia' command in Terminal
- Connect the USB flash drive or other volume you're using for the bootable installer. Make sure that it has at least 12GB of available storage and is formatted as Mac OS Extended.
- Open Terminal, which is in the Utilities folder of your Applications folder.
- Type or paste one of the following commands in Terminal. These assume that the installer is still 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.
Catalina:*
Mojave:*
High Sierra:*
Sierra:
El Capitan: - Press Return after typing the command.
- When prompted, type your administrator password and press Return again. Terminal doesn't show any characters as you type your password.
- When prompted, type

to confirm that you want to erase the volume, then press Return. Terminal shows the progress as the bootable installer is created. - When Terminal says that it's done, the volume will have the same name as the installer you downloaded, such as Install macOS Mojave. You can now quit Terminal and eject the volume.
* If your Mac is using macOS Sierra or earlier, include the
--applicationpath
argument, similar to the way this argument is used in the commands for Sierra and El Capitan.Use the bootable installer
After creating the bootable installer, follow these steps to use it.
- Connect the bootable installer to a compatible Mac.
- Use Startup Manager or Startup Disk preferences to select the bootable installer as the startup disk, then start up from it. Your Mac will start up to macOS Recovery.
Learn about selecting a startup disk, including what to do if your Mac doesn't start up from it. - Choose your language, if prompted.
- A bootable installer doesn't download macOS from the Internet, but it does require the Internet to get information specific to your Mac model, such as firmware updates. If you need to connect to a Wi-Fi network, use the Wi-Fi menu in the menu bar.
- Select Install macOS (or Install OS X) from the Utilities window, then click Continue and follow the onscreen instructions.

One of the most common mistakes I see among new Mac users is fumbling with how to install 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. https://nnnuwb.weebly.com/dmg-mori-ntx-2000-lost-spindle-orientation.html. 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. Dmg icon before and after. Or, go to the Desktop, click once on the icon, and press CMD+E.
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: Yandere simulator download mac.
- Find the downloaded file, which usually ends up in your Desktop or Downloads folder.
- Double-click the .DMG file to mount it. A new Finder window showing its contents should appear.
- If the window also contains a shortcut icon to “Applications”, drag and drop the app onto the shortcut.
- 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.
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:
- Close any Finder windows that have been left open.
- Eject the disk image (not the .DMG file). Click on its desktop icon, then press CMD+E.
- Delete the .DMG file by dragging it to the trash.
That’s it! Your new Mac application is ready to use. But wait…
