Hi, I was just wondering a few things. First, what is a.dmg file? And second, after I install an app using a.dmg file, can I delete the.dmg file without affecting the app? Thanks so much:). Once the Basesystem.dmg file is ran on your Mac, it may begin performing different malicious activities. These may be of all tpes, but the main one is spyware and virus actions. The bad news here is that once you try to delete Basesystem.dmg, the Mac asks to enter the password and identify as an administrator.

A DMG file is Apple's equivalent of an ISO installation file or disk image. It usually contains all the information required to install a program on a Mac computer running Mac OS X or macOS. It is also a container to hold macOS installation image. If you want to create a bootable macOS bootable disk, the first step is to burn DMG to USB or DVD.

However, native support for DMG files is only available on Apple's desktop operating system. For Windows or Linux, you will need to use different methods. For example, if you want to burn a DMG file to USB on a Mac, it's as easy as using the built-in Disk Utility tool. On Linux and Windows, you obviously have to use other ways. This article explains how to burn a DMG file to a USB flash drive on a Mac, a Windows computer and a machine running Linux.

Method 1: How to Burn DMG to USB on macOS or Mac OS X

If you have a Mac, then Disk Utility will help you create your bootable USB drive. Since this is a native application, no downloads are required. The built-in tool will be able to directly burn the DMG file to a disk or drive. You simply have to follow the process as described below:

Step 1: Open Disk Utility by going to Applications >> Utilities and clicking on the tool.

Step 2: You should be able to see all the drive names in the left-side panel. Now open a Finder window and drag your DMG file into Disk Utility. Drop it in the blank area below the drive names on the left panel.

Step 3: You can now insert your USB drive and wait for it to appear in the drives list. Next, click on your mounted DMG file on the left panel and click on ‘Burn' in the top toolbar. When you see the ‘Burn Disk In:' message, click on the USB drive.

The DMG file will now be burned to the USB drive, and you can use it to do program installations. Bluestacks for mac download. Disk Utility has a good burn success rate, so hopefully you won't have to repeat the process to get it right.

Method 2: How to Burn DMG to USB in Windows 10 (Bootable)

Since Windows doesn't natively support DMG files, you will need to first download and install a utility that can handle such disk images. The best software for the job is WizDMG, a Windows-based desktop solution for authoring Apple's disk image files in a non-Mac environment.

WizDMG requires no technical expertise to use. The clean interface only shows the user the necessary functions, and all the heavy lifting is done at the back end. One of the unique features of this increasingly popular software is the amount of beta testing it has gone through. Extensive and gruelling tests with different storage media brands and Windows versions have made this one of the most reliable DMG utilities for Windows. With one of the industry's highest burn success rates, it's no wonder that WizDMG is emerging as the leader in its class.

Step 1 Install WizDMG

Download WizDMG to your Windows PC and install the program by following the setup instructions in the wizard.

Step 2 Load DMG File into WizDMG

After launching the program, you'll see various options on the home page. Click on 'Burn' to kick off the process. Now click on 'Load DMG' to add the file to the program, and insert a USB flash drive.

Step 3 Start Burning DMG to USB

The drive will be automatically detected by the software, so all that's left is to click on 'Burn' and wait for your drive to get ready.

The USB drive will contain the DMG image you selected, and this can now be a portable boot drive to install that particular program on any Mac computer.

Method 3: How to Burn a DMG File to USB in Linux

The process of burning a DMG to USB in Linux is a little more complicated since it requires converting the file to an ISO before burning it to a drive. It also requires command line executions, but if you own a Linux machine you may already be familiar with command line work. Please note that in order for the USB drive to be bootable, the original DMG must have boot information. In here, we take Ubuntu Linux as an example.

Step 1: Download and install dmg2img by using the following command: sudo apt-get install dmg2img

Step 2: Convert the DMG to IMG with the following command: dmg2img sample.dmg

Step 3: Change the filename of the resulting .img file to .iso. Remember, this is still an IMG file, but it will have a .iso extension. Use the command below to do this: mv sample.img sample.iso

Step 4: Insert the USB drive, but make sure it is not mounted. If it is, you can unmount it with the following command: sudo umount /media/

Make sure you know the file path to the mounted USB drive. Although external drives are generally mounted in /media in Linux, it could be in a different location. To check, you can use this command: lsblk

This command reads the sysfs file system and shows you information about block devices. Your drive can usually be identified by the size, but make sure you use the correct disk name, not the partitions within the disk.

Step 5: You can now burn the DMG to the USB drive with the following command:

sudo dd bs=4M if=sample.iso of=/dev/sdX %% sync

If the original DMG file was bootable, then this .img version on your USB will also be bootable. The process looks a bit complicated, but it should work as long as you follow the steps described above.

The Bottom Line:

As we can see, burning DMG to USB on Mac is the easiest solution as you don't need to install any other tools or type command to complete the task, which could be annoying for some users. How about the Mac was broken and you want to create a bootable macOS disk to repair the computer? That depends what kind of computer you get at hand. Just follow the steps listed above according to the computer model.

Can We Delete Dmg Files After Installation

Copyright © 2015 AndroidPhonesoft. All Rights Reserved. Android is a trademark of Google, Inc

One of the aspects where Macs differ from Windows PCs the most is when it comes to installing applications. On Macs, you need mount a disk image and then unmount it and delete once the installation is finished, which can be a bit of a hassle, especially if you have to test many apps in a short amount of time.

Thinking of that, this time we’ll share a couple of neat little workflows that you can implement on your Mac using Automator. With any of them, every time you are done with an app installation on your Mac, you’ll be able to eject/unmount and delete the disk image in just a couple of clicks.

Let’s get started with how to set up these nice Automator workflows.

Delete DMG Files Automatically When You Eject Them

Step 1: Open Automator and choose to create a new document. From the available document types that show up on the dialog box, select Service.

Step 2: At the top of the right panel, make sure to choose from the dropdown menus the options ‘no input’ and ‘Finder’ respectively so that the end result is as the one pictured below.

Step 3: Next, on the left panel of Automator, search for the Run AppleScript action and drag it to the right panel. An AppleScript window will show up with some placeholder code in it.

Delete that code and instead copy and paste the following one in the script box:

tell application 'Finder'
set selection_list to selection
if (count selection_list) < 1 then
display dialog ¬
'Please select a volume mounted from a disk image.' with title ¬
'No Selection Found' with icon stop ¬
buttons ['OK'] default button 1
return
end if
set my_selection to item 1 of selection_list
set my_kind to kind of my_selection
set my_name to name of my_selection
if my_kind is not 'Volume' then
display dialog ¬
'Please select a volume mounted from a disk image file.' with title ¬
'Selection is not a Disk Image' with icon stop ¬
buttons ['OK'] default button 1
return
end if
set volume_list to paragraphs of (do shell script 'hdiutil info grep ^/dev/disk grep -o '/Volumes/.*')
set source_list to paragraphs of (do shell script 'hdiutil info grep ^image'-'alias grep -o '/.*')
set match_found to false
repeat with v from 1 to (count volume_list)
if '/Volumes/' & my_name = item v of volume_list then
set match_found to true
exit repeat
end if
end repeat
if match_found is not equal to true then
display dialog ¬
'The selected volume does not appear to be a Disk Image.' with title ¬
'Could not find Disk Image' with icon stop ¬
buttons ['OK'] default button 1
return
else
set my_source to POSIX file (item v of source_list) as alias
move my_source to the trash
eject my_selection
--reveal my_source
end if
end tell

Step 4: Now save this Automator service and give it a name that is easy to remember.

Step 5: Once this is done, every time you have a disk image mounted, all you have to do is select it and on the Finder menu select Services and then Eject and Delete (or whatever you named the service you just created) and the disk image file will be both unmounted and deleted with one click.

Now, let’s take a look at another Automator workflow that achieves the same objective doing exactly the opposite.

Eject DMG Files Automatically When You Drag Them To the Trash

As you can see from the title, this Automator workflow allows you to achieve the same purpose, except that in reverse, so you can avoid this message every time you drag to the trash a mounted DMG file.

Here are the steps to create it.

Step 1: Create a new document in Automator and select Folder Action from the available document types.

Step 2: At the top of the right panel, select Other… from the dropdown menu. Then, on the dialog box that pops over, type ~/.Trash to work with that folder.

Step 3: Next, on the left panel, drag the Run Shell Script action to the right panel. On the two dropdown menus that show up, select /usr/bin/python and as arguments respectively.

Step 4: Replace the placeholder script in the script box with the following one:

import string, os, sys
lines = os.popen('hdiutil info').readlines()
should_eject = False
for line in lines:
if line.startswith('image-alias'):
path = line.split(':')[1]
image_path = path.lstrip().rstrip()
if image_path in sys.argv:
should_eject = True
elif line.startswith('/dev/') and should_eject is True:
os.popen('hdiutil eject %s' % line.split()[0])
should_eject = False
elif line.startswith('###'):
should_eject = False

Once done, save the Folder Action and quit Automator. Now, whenever a DMG file is mounted, all you’ll have to do is drag it to the Trash and it will be unmounted at the same time.

Cool Tip: You can also create keyboard shortcuts for these actions by following the instructions at the end of this tutorial.

And there you go. Two different workflows to enable a very convenient feature on your Mac. Now all left to do is just choose which one you find more convenient. And the best of all? In both cases you’ll learn a bit more about Automator. Enjoy!
