Many applications are distributed as disk images, a compressed binary format. If you double click a disk image in the Finder, it is mounted automatically. Once mounted, installation of the application is typically done by dragging an icon to the Applications folder. The same can be accomplished from the command line using two commands, hdiutil and cp.

The following steps show the installation of a popular VNC client for OS X called 'Chicken of the VNC'. It can be used as a remote desktop client for Linux, Mac, or Windows hosts.

The download file is named 'cotvnc-20b4.dmg'. Here are the steps needed to install it remotely from the command line.
note: this technique can be used from a local Terminal window or a remote SSH connection.

Mount the disk image

The first step is to mount (or attach) the disk image. From the command line, use:
hdiutil mount cotvnc-20b4.dmg
I received the following output:

A mounted disk image appears on the Desktop, in the Finder, and more importantly shows up as a directory in /Volumes. In this case, the last line of output from hdiutil showed exactly where the disk image was mounted.

Sometimes when a disk image is mounted, it will prompt you to agree to a license first. In that case, the text that would normally appear in a GUI dialog box instead appears in the Terminal window. Once you scroll to the bottom of the agreement, you can type in Y to continue or N to stop. The Firefox disk image is one example of a package that displays a license before mounting.

Install the application

Use the cp command to copy the application to /Applications:
sudo cp -R '/Volumes/Chicken of the VNC/Chicken of the VNC.app' /Applications

How To Install Dmg Without Admin

The -R switch means to copy recursively, in other words, copy everything from that location including all subdirectories and files below. It is important to leave off the trailing '/' from the 'Chicken of the VNC.app' directory, or the command will not copy the directory itself, just the contents. After entering your password, the application will be installed and ready to use.

Most applications can simply be copied to the /Applications directory. However, some are distributed in a .pkg format and must be installed using the installer command instead of cp. To install a .pkg, use this command:
sudo installer -package /path/to/package -target '/Volumes/Macintosh HD'

Unmount the disk image

To tidy up, return to your home directory and unmount the disk image:
cd ~
hdiutil unmount '/Volumes/Chicken of the VNC/'

You should see this message after the unmount:
'/Volumes/Chicken of the VNC/' unmounted successfully.

Installing applications from a .dmg package at the command line is not something you need to do every day. But it is a nice tool to have if you want to install an application on a remote server or script the installation of a package to a group of desktop Macs.

A macOS USB installer saves much time when you want to install the OS offline on two or more Macs. Also, it helps in recovering a system after a startup failure. It is easy to make a macOS USB disk from the full installer downloaded from the App store; Apple provides clear-cut instructions for the same. However, people use this feature only when they have a problem with their computer, mainly when their system is not booting up. In this post, we explore the ways to make a bootable macOS USB for Catalina 10.15 and others from Windows PC and Mac.

Make macOS Catalina 10.15 USB installer on Windows PC

TimeMachine is the safest option to recover a broken Mac in the offline mode. If a backup is not there, you have to go for a clean installation either from a bootable USB/DVD drive or the Internet. In my case, I lost the boot partition of my iMac and didn’t have a TimeMachine backup. Internet recovery was showing up, but it kept on failing to download the OS files from the servers. As it is my only Mac, I had no option left, until I found the method to use a Windows PC to create a Mac OS bootable USB installer. I did this for making a macOS High Sierra USB drive, and later I was successful in reinstating my iMac. As of now, the OS is Mojave, but the process given below is compatible with all editions of macOS including the upcoming macOS Catalina 10.15.

Step 1: Download macOS Catalina [DMG] for Windows

As said in the beginning, a Mac is must for creating bootable macOS USB disk. If you think about doing it from Windows, the options are limited. The cross-compatibility of extensions for the two OS are entirely different. Luckily some Windows applications support a bootable macOS disk format, DMG. Hence, If we can download macOS DMG file, then it possible build the USB installer from Windows environment.

Most of the sites talking about the bootable macOS USB installer on Windows is not guiding on how to download the required DMG files for the method. Check our page to download macOS Catalina installer installer in DMG format for Catalina, Mojave and High Sierra.

Step 2: Partition USB disk on Windows to make it bootable on Mac

Here we are creating a UBS installer for Mac on Windows. So make sure that we keep the partition of the USB disk to have an appropriate scheme. Converting the USB disk to have a GUID partition table (GTP) is recommended for this method work effectively.

Connect the USB disk to Windows and run the above-given commands in the correct order. It cleans and converts the USB disk to GUID partition table if it is using MBR or something else.

Step 3: Make bootable macOS Catalina USB installer on Windows 10

When the Internet recovery is stuck and fails to download the OS files, you could use Windows to make a bootable macOS USB installer. Out of the two or three software for handling macOS installer [dmg] in Windows, Transmac is the best one. Transmac is not free, but the developers offer a 15-day trial period, and that is sufficient for one-time use. Now let’s move on to the steps to create macOS Catalina USB disk on Windows.

1. I already have the macOS Catalina 10.15 dmg file on my Windows desktop.
2. Install the Transmac 12.4 trial for Windows; download here.
3. Right-click on Transmac icon, and select to run it with Admin privileges.
4. As shown in the screenshot, right-click on your USB disk and pick the option Restore with Disk Image.
5. Point the Windows Explorer to the location where you have the bootable macOS DMG file.
6. Wait until the software completes restoring the USB disk with Install macOS Catalina app.
7. The disk is ready when you see the message “Restore Complete”.
8. If you click on the just-made USB installer on Transmac, you could see the macOS Catalina 10.15 files present in the drive.
9. Now safely remove the USB and connect it it the Mac you would like to recover.

Here we focus on preparing macOS Catalina 10.5 USB installer on Windows. But this method is same and applicable for Mojave, High Sierra and all previous versions up-to OS X Lion.

The recovery partition in a Mac helps in restoring it from TimeMachine or the Internet when there is a system failure. It keeps the essential apps like Disk Utility, which aids in re-installing a fresh copy of macOS. However, this partition gets deleted when you change your Macs hard disk to SSD or like. A bootable macOS USB installer comes helpful in such situations. It is also useful when you want to install macOS on a couple of offline systems without wasting bandwidth and time.
