This sample code project uses the Compression framework to encode (compress) and decode (decompress) files by dragging them to the app window. The app decompresses files with an extension that matches a supported compression algorithm (that is,.lz4,.zlib,.lzma, or.lzfse), and compresses all other files.

The files are slightly smaller than zlib-compressed disk images, with encoding that is twice as fast and decoding that is three times as fast. This is DropDMG’s recommended format for general use if your files can require macOS 10.11.

Dmg file contains a volume with identifier AppleHFS, which is compressed with various methods (zlib, bz2, etc.), how can I extract a raw, uncompressed HFS volume from DMG file? Right now, it cannot be done with Catacombae - HFSExplorer, due to unknown block type, with the 0x80000007 identifier, which is probably LZFSE compression method, 7z.

Code-sign your.dmg so that macOS knows it can be trusted after download.

You can use 7-Zip on any computer, including a computer in a commercial organization. You don't need to register or pay for 7-Zip.

The main features of 7-Zip are:

High compression ratio in new 7z format with LZMA compression

Strong AES-256 encryption in 7z and ZIP formats
Self-extracting capability for 7z format
Integration with Windows Shell
Powerful File Manager
Powerful command line version
Plugin for FAR Manager

What's new after 7-Zip 16.04:

Minor speed optimization for LZMA2 (xz and 7z) multi-threading compression.
7-Zip now uses additional memory buffers for multi-block LZMA2 compression.
CPU utilization was slightly improved.
7-zip now creates multi-block xz archives by default. Block size can be
specified with -ms[Size]{m|g} switch.
xz decoder now can unpack random block from multi-block xz archives.
7-Zip File Manager now can open nested multi-block xz archives
(for example, image.iso.xz) without full unpacking of xz archive.
7-Zip now can create zip archives from stdin to stdout.
ZIP unpacking code was improved.
7-Zip now can unpack OBJ/COFF files.
7-Zip now can unpack DMG archives that use LZFSE compression method.
7-Zip now doesn't allow update operation for archives that have read-only attribute.
7-Zip command line: @listfile now doesn't work after -- switch.
Use -i@listfile before -- switch instead.
new -sse switch to stop archive creating, if 7-Zip can't open some input file.
7-Zip now reserves file space before writing to file (for extraction from archive).
It can reduce file fragmentation.
Internal changes in code.

The BUGs were fixed:

7-Zip could add unrequired alternate file streams to WIM archives,
for commands that contain filename wildcards and -sns switch.
Extracting from tar with -si switch didn't set timestamps for directories.
Some bugs were fixed. 7-Zip could crash in some cases.

What's new after 7-Zip 18.00 beta:

7-Zip now can unpack DMG archives that use LZFSE compression method.
7-Zip now doesn't allow update operation for archives that have read-only attribute.
The BUG was fixed: extracting from tar with -si switch didn't set timestamps for directories.
Some bugs were fixed.

Home > Resources > Make Bootable USB Installer from DMG

(0 comments)

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.

There is also the possibility of converting the file into a format more suitable for Windows, which is the ISO file format for disk images. Considering the above, let's look at different ways to create a bootable drive from a DMG file on a Windows computer.

Part 1: Convert DMG to ISO and Make Bootable USB from ISO

Since Windows doesn't offer native support for DMG files, you can first convert the file to ISO. Why? A lot of easier to find an app for making a bootable USB from ISO file. The easy way to do this is to use Command Prompt. Don't be intimidated by the non-GUI environment even if you don't have any experience. If you follow the steps below, you can convert any DMG file to ISO and then create a bootable USB using the converted file.

Step 1: Open Command Prompt by typing cmd in the Run windows and hitting Enter.

Step 2: In the command interface, go to the directory in which the DMG file is saved. You can do this by using the 'cd' command followed by the file path, then pressing Enter. For example, if your disk image is in D: and Command Prompt is currently in 'C:', then type 'd:' (no quotes) and press Enter. If it is in a subfolder, type 'cd subfolder', and so on.

Step 3: Use the following command to convert the DMG file to ISO:

hdiutil convert /path/sourceimagefile.dmg -format UDTO -o /path/targetmage.iso

Step 4: Once the ISO file has been created, you can use a burning tool to create the bootable USB drive. To do that, continue with this guide.

Cons:

File damged or broken after conversion.
Failed booting from burned USB disk.
May not work with the latest DMG file.
Complex and take more time.

Part 2: Create Mac OS X Bootable USB Installer from DMG

Androidphonesoft DMG Editor is a powerful software application for Windows that will allow you to manage the non-native DMG format even if you have no experience. The interface is uncluttered, and you can even use the tool to view files, extract them, edit the DMG and even copy it to a disk. The burn function has one of the highest success rates in the industry, which makes this an ideal utility for our purpose.

Created by the talented team of developers at Androidphonesoft, DMG Editor is currently the most intuitive Windows app for handling Apple's disk image format. Each of its functions have been tested on various Windows versions, with different types of DMG files and on different PC brands. This thorough testing means no wasted DVDs or corrupted files. As long as your DMG file is in good shape, you can directly create a bootable disk.

Step 1 Install DMG Editor

Download and install DMG Editor on your Windows PC.

Step 2 Plug in USB Drive

Launch the application and click on the 'Burn' section. You will also see other modules such as Edit, Extract.

Step 3 Load DMG File

Now import the DMG file by clicking the 'Browse' button and choose the USB drive name.

Step 4 Start Burning DMG to USB Drive

Click 'Burn' button at the bottom of window to start burning DMG file to USB drive. Once it get started, it displays a progress bar and you have to wait for the task to be finished. Usually, it takes 20 minutes depending on how large the file is.

In a few moments, your bootable USB flash drive will be ready for use. Since you haven't done any conversion, you can use this directly on a Mac for program installation, which you cannot do with the first method.

Part 3: Create Bootable USB from DMG in Windows Via PowerISO

Another well-known disk image utility is PowerISO. Apart from being ideal for burning ISO files, it can also burn a DMG file to USB to create a bootable drive. There are some settings that you have to keep in mind when burning with this software, but it's easy to get the hang of it once you do it a couple of times.

Step 1: Download PowerISO and install it in your Windows PC. Launch the app and insert a USB drive into a free USB slot in your computer.

Step 2: You can import the DMG file directly by clicking on ‘Burn' in the toolbar or going to Tools >Burn. In the Burn window, select the DMG file from the Source File section.

Step 3:Now review the settings to select the burn speed. The default will be the maximum your hardware can handle, so you can reduce that. You can also choose to finalize the disk and verify it. Finalizing means you can't save any more files on the drive, but it primarily applies to DVDs and CDs. Choosing ‘Verify' will prompt the software to execute an additional process after the burning is done. Any errors in the bootable USB will show up at that point.
