If you want to do it from the command line, you can use hdiutil like so: hdiutil create -volname WhatYouWantTheDiskToBeNamed -srcfolder /path/to/the/folder/you/want/to/create -ov -format UDZO name.dmg Man hdiutil for more details.
First, mount the dmg image : sudo hdiutil attach <image>.dmg The image will be mounted to /Volumes/<image>. Mine contained a package which i installed with: sudo installer -package /Volumes/<image>/<image>.pkg -target / Finally unmount the image: sudo hdiutil detach /Volumes/<image>.
All volumes, including DMGs, are mounted in /Volumes. You can get a list of mounted volumes by typing ls /Volumes in Terminal. You can navigate to a Disk Image using cd /Volumes/nameOfImage.
The problem appears to happen when you unmount the image using umount. Remount the image (either using hdiutil attach or just double click the image) and use the command hdiutil detach it again. This will unmount and eject the image. hdiutil detach /Volumes/<your image>
From the DropDMG manual: Sparse bundle disk images appear as a single file but are actually stored as a folder with many files inside. This makes it more efficient to back them up using Time Machine or other backup utilities, as only the changed parts need to be copied. Additionally, sparse bundle disk images work well with the Compact ...
Technically, a .pkg is not a file, but a folder. So maybe collecting it into a single file is essential for downloading.
Renaming .cdr to .iso is a bad advice. An .iso has a slightly different format that allows PC users to play the DVD as well. A way to convert a .cdr to an .iso is: $ hdiutil makehybrid -iso -joliet -o [filename].iso [filename].cdr
The error message is pretty unclear, but one reason might be that you are not connected to the power outlet. Compacting a disk image might be a long and intensive task, and sometimes the OS denies it when you are running on battery to avoid any risk of data loss. If you are positive that you have enough battery power to complete the task, you may overrun ...
.dmg files are disk images, similar to an .iso file. You can think of them like a virtual CD. You put it into the CD drive (mount it), and its contents appear on your computer. When used for software downloads, they are simply a way to bundle up files, like in a ZIP archive. Their advantage is that it's possible to customize the design (e.g. Finder window ...
Yes, Disk Utility can do this. Use Convert then select your dmg file. In the Save As dialog that follows, select DVD/CD master. Disk Utility will insist on saving the new ISO as a .cdr file, but it is really an ISO. You can rename it to .iso in the Finder, if you like. At http://osxdaily.com/2012/07/18/convert-dmg-to-cdr-or-iso-with-disk-utility/ there are ...
You should be able to mount the .dmg using: hdiutil attach /path/to/file.dmg And then copy its contents (which appears in /Volumes) where ever you like.
I've been interested in this question since Nov 2012 and even set up a FreeNAS VM to reproduce the issue. I eventually gave up but since the question has been resuscitated I will share what I found out back then and in the last hours (luckily I didn't delete the VM) and what I think the cause for this issue is. I have also found a workaround. My setup ...
The hard-drive looking thing on the desktop is a mounted disk image; the .dmg file is the file where the data for the image is. To get rid of the image, unmount it. There are three four five good ways to do it: Drag the disk to the trash. The trash will turn into an eject icon while dragging. Highlight the disk on the desktop and select File > Eject in ...
Data on DMG image can be checked for integrity with Disk utility. You can make it mandatory for the user to agree to license before mounting dmg. It could be locked from modification. You can easily add hidden files and folders on DMG. You can make background image. You can make it safe from stripping during transit through non-metadata aware file systems ...
An application on a Mac is just a folder full of files with a .app extension. However, OS X hides this fact from you and displays the folder as a file with an icon. Now when you download something it's very uncomfortable to download folders (without a download manager). Therefore this "App Folder" has to be put inside a single file somehow. This can be done ...
This is exactly what a dmg does. To create one use Disk Utility and hit the New Image icon. Then choose the size, encryption and choose the image format as one of the sparse images. Even if you choose a large size it will only take up space according to what you save in it.
Sparse bundle disk image is an optimized form of the sparse disk image. It optimizes intentionally to reduce network load upon backup of changes to the filesystem at the expense of time and space. Specifically it uses a hashing function to store bits of data across a large directory structure which allows changes to be isolated in smaller band files. When ...
A lot of applications (bundles) for OS X don't need an installer in contrary to almost all Windows apps. They are distributed inside an .dmg. To properly "install" them just open the .dmg and copy the app file to /Applications or /Applications/Utilities. A lot of images already contain a soft link to the Applications folder to be more convenient for the ...
An article written by someone else who did that: http://blog.whitehatsec.com/cracking-aes-256-dmgs-and-epic-self-pwnage/ The author did get his cracked, but had to borrow a supercomputer to do so even after he got custom software designed to use partial knowledge of the password he had chosen. It shows how hard a general cracking effort would be, but ...
A .dmg file is kind of like an USB stick in a file and can be handled more or less the same way. To install from a .dmg file you usually do the following: double click the .dmg to make its content available (name will show up in the Finder sidebar), usually a window opens showing the content as well drag the application from the .dmg window into ...
I have an external hard drive with several installers on it. All you need to do is make several partitions, each large enough for the disc you're imaging. (My drive has 10.4 Tiger PPC, 10.5 Leopard PPC, 10.5 Leopard Intel, and 1.6 Snow Leopard on it, and I have a Lion USB flash drive.) I made the images using Disk Utility's Restore feature. Select the ...
Dreamweaver CC came in two major versions: the initial CC release (v13) and the CC 2014 release (v14). From the file names, you can infer which is which. As for a "full installer", there is no such animal now. You install CC apps individually through the Creative Cloud Manager which downloads and installs the selected app(s).
You can not install XCode on any version of Windows, it only runs on OS X.
It doesn't matter what type the DMG is as VMware Fusion cannot install OS X Yosemite by booting it or even booting the Install OS X Yosemite.app downloaded from Apple as that's not how it works in VMware Fusion. VMware Fusion must first make an Installer Image from the Install OS X Yosemite.app and install from the Image it creates. Have a look at: ...
In Finder you can show or hide the disks and other devices Go to the sidebar and mouse over DEVICES you get to the right text that says Show or Hide. Click on that word to toggle the display of the devices.
DropDMG I use and recommend DropDMG since it has many features that make it useful for sharing software such as scripting the building of a DMG file directly from my CI server when I promote a build using the included CLI tool dropdmg. Above: Many options for configuring a DMG file, including layouts and showing a license when opening the DMG.
It depends on your viewpoint: a file written to an encrypted disk image is immediately written encrypted to the HDD/SSD where the disk image resides. Since the file system of the unlocked disk image is still mounted, the file appears as "unencrypted". So a user, who can access the raw HDD/SSD only, can't read/decode the file content, but a user with the ...
Some step by step instructions can be found here. After opening Disk Utility: Click the New Image icon Place the contents of folder/directory into the newly created disk image.
After Mountain Lion is installed, your Mac auto-deletes "Installer Mountain Lion.app". So before installs or upgrades like that, you must make a backup (compress it and move file compressed to anywhere, where you put storage data). And now, you need to download "Installer Mountain Lion.app" again from the App Store.
A DMG can be set to display a license agreement before it will allow you to open it. This is normal and nothing to be alarmed about. Once you accept the license agreement, it will mount and open the normal Finder window showing its contents. See this thread on Cocoa Builder. There is no way to disable it and nothing is being auto-run.
