I want to install a dmg file on a remote server. All I have is an ssh access. Since a DMG is a disk image, I tried to mount it, but mount does not seem to recognize its format. File says my dmg f. If you need to install it to another location you can, just make sure to remember exactly where, you’ll need to know in an upcoming step. After you’ve installed 7-Zip, double-click (or tap if you have a Windows 10 tablet) the.RAR file you want to open. Select More apps from the menu that appears. Now select Look for another app on this PC; When the “Open With” dialog box appears, double-click your C: drive and then the Program Files folder (as illustrated in the screenshot below). After installing DMG Extractor, all you have to do is double-click your DMG file to open it up. You can browse the files right in the DMG Extractor window if you just want to see what’s inside the DMG file. If you need to extract the file, click the “Extract” button on the toolbar, and then choose one of the extraction options.
If something doesn't quite work right after you've installed macOS Catalina, you can reinstall the operating system so it is a fresh copy. Reinstalling a fresh copy of macOS Catalina will not affect your current settings. Applications and settings will remain the same. Completing this process replaces the core files of macOS Catalina in case something wasn't working right before.
Before you start: Back up your data
- It is a good idea to perform one full backup before starting with a clean copy of macOS Catalina. You can also back up files and documents using a cloud-based storage system like Dropbox, OneDrive, or the easiest: iCloud.
- Make sure the computer on which you're installing a fresh copy of macOS Catalina can be connected to the internet, either via Wi-Fi or Ethernet. This step is important. An Internet connection is needed in order to reinstall the macOS operating system.
- If you are using a laptop, make sure it is connected to a power source.
How to install a new copy of macOS Catalina in Recovery Mode
Recovery Mode is the special salvation of the Mac that first launched with OS X 10.7 Lion. It creates a temporary boot partition that allows you to access certain things on your computer that you might not be able to if your system froze or crashed. It is the easiest way to install a fresh copy of an operating system.
- Connect your Mac to the internet via Wi-Fi or Ethernet
- Click on the Apple icon in the upper left corner of your screen.
- Select Restart from the drop-down menu.
- Hold down Command and R (⌘ + R) at the same time. When you hear the startup chime (or when the screen goes black on newer Macs), keep holding the keys until your computer reboots.
- Click on Reinstall a new copy of macOS.
- Click Continue.
- Click Continue again when the installer window appears.
- Agree to the software terms and conditions.
- Select your hard drive.
- Click Install.
- Complete the installation process.
How to update to Catalina after reinstalling an earlier macOS
When you install the latest operating system from Recovery Mode, sometimes, your Mac will install an older operating system, like High Sierra or Mojave. Once the older operating system installation is complete, you can then download Catalina as a software update.
Remember, you must have an internet connection in order to download a fresh copy of the Mac operating system.
- Open System Preferences.
- Click on Software Updates.
- Click on Update Now.

So you’re running Linux on your computer, maybe Ubuntu, and you have some files with the .dmg extension. In this guide, we’re going to talk about how to open, mount, extract, and otherwise get your files from these pesky DMG images. You could always just extract the files on a Mac, then transfer them back to your Linux machine. But if you really want to do this on Linux, without having to rely on Mac, here’s how to do it.
What are DMG image files?
Simply put, it’s a kind of image file. But not an image like a jpeg is an image. DMG is Apple’s proprietary disk image format, native to Mac OS X. There are actually a whole bunch of different types, format and options within this format. There are options for encryption, compression, and different kinds of partition schemes, among others. Unfortunately, this can make things pretty confusing when we’re trying to gain access to the data contained in one of these images.
DMG images are typically a kind of Universal Disk Image Format (UDIF), although there are others, namely NDIF and SPARSE. Although the .dmg file extension is usually used, they can also sometimes have an .img extension, or in some cases no extension at all. Their MIME type is application/x-apple-diskimage.
The HFS/HFS+ (Mac OS Extended/Journaled) file system is typically used in DMGs. However, this isn’t always the case. You may also sometimes find FAT and ExFAT files systems, as well as variations on HFS.
Does my system support DMG?
Perhaps the biggest hurdle to overcome when trying to work with DMG files is working with the HFS file system (Mac OS Extended). Linux supports HFS through the “hfs” and “hfsplus” kernel modules.
There’s an easy way to test if your system has these kernel modules. Plug in a USB drive formatted with the Mac OS Extended file system. If your particular distribution doesn’t have the appropriate modules, you will likely get an error message. On Ubuntu, you’ll get a popup window declaring “Ubuntu: Unable to mount '.
Alternatively, we can see if the kernel module files are present with find:
We want to see two files: “hfs.ko” and “hfsplus.ko”. If find doesn’t return these files, your system probably doesn’t support HFS.
You could also try “modinfo”:
modinfo hfs
and modinfo hfsplus
should return something like:If you get '
modinfo: ERROR: Module hfsplus not found
' your system doesn’t have these modules.Not all Linux kernels and distributions support HFS. This is especially the case for certain distributions that are a few years old. If you have kernel support for HFS, great! If not, don’t worry. There are still ways to extract data from your DMG files. While it’s nice to have the option to mount the images we’re working with, this is really the only functionality we’re losing without having the hfs and hfsplus modules. The two programs we’re going to use later on (P7ZIP and dmg2img) do not require kernel support to function.
What kinds of DMG images can be opened in Linux?
This guide is about how to open, mount, and extract files from read/write, read only, and compressed DMG image files. The following partition schemes have all been tested with the techniques discussed here.
- Apple Partition Map
- CD/DVD (partitioned)
- CD/DVD (partitioned) with ISO data
- Hard disk
- Master Boot Record Partition Map
- No partition map
This guide does not cover how to handle sparse disk images (.sparseimage), sparse bundle disk images (.sparsebundle), or CD/DVD masters. DMG images with partition scheme types of “CD/DVD” and “GUID Partition Map” do not appear to work with the techniques described here.
Option 1: Mount the DMG
If the Linux distribution you’re on has HFS support in the kernel (Ubuntu 14.04.1 LTS supports it), it’s pretty easy to just mount the DMG image:
We’re using “sudo” because we need root privileges to mount things. The HFS+ file system type is specified with “-t hfsplus”. The “/mnt” at the end of the command specifies where we’re mounting the image.
Unmount the image with
sudo umount /mnt

If you get a wrong fs type message like the one below, it means the DMG file is either of an unsupported type, or it’s compressed. Unsupported images include sparse images, sparse disk bundles, CD/DVD masters, and images with partition schemes of the CD/DVD or GUID Partition Map types.
Use “file” to learn a little more about the image file:
If you get
image.dmg: x86boot sector
that means it’s probably using a GUID Partition Map and isn’t supported. This isn’t good, however, it’s also not too terribly common.Do You Need To Keep Dmg Files After Install Windows 7
What’s more common is to see something like this:
If mounting isn’t working, and this is what you’re seeing with “file image.dmg”, then you’re luck!. Our problems are being caused by compression. Linux doesn’t like to mount compressed DMG images. To get around this little obstacle, we’ll use dmg2img (see below).
Option 2: Use dmg2img for compressed images
So you have a DMG image that you can’t mount because it’s compressed. You’ve done “file compressed_image.dmg” and you got “compressed_image.dmg: bzip2 compressed data”. The fix? That’s easy: use dmg2img to convert it to an uncompressed image. Once you run the image through dmg2img you should be able to mount it no problem.
Don’t have dmg2img? It’s usually pretty easy to get using your distribution’s package management. On Ubuntu, you’d do:
Using dmg2img isn’t very difficult. Type “dmg2img” into the command line followed by the name of the DMG file you want to decompress. The Mac OS X version of Firefox is a good example of a compressed DMG file.
Now mount the resulting .img file:
Option 3: Extract DMG contents with P7ZIP
P7ZIP is awesome. It’s the Linux/BSD version of 7-Zip. Check out their SourceForge page here With it you can literally extract files from any kind of image or archive. Just kidding… It doesn’t really work with every format conceivable. However, it can handle (in alphabetical order): ARJ, CAB, CHM, CPIO, CramFS, DEB, DMG, FAT, HFS, ISO, LZH, LZMA, MBR, MSI, NSIS, NTFS, RAR, RPM, SquashFS, UDF, VHD, WIM, XAR and Z. Impressed? I certainly am!
Installing p7zip is pretty easy using your distribution’s package management system. On Ubuntu with apt-get:
In addition to being able to extract data from compressed and uncompressed images alike, P7ZIP doesn’t require the HFS kernel modules at all. In the example below, we’re going to extract all of the files from “Firefox 33.1.1.dmg”. When we’re done, we’ll have a tidy little folder called “Firefox”.

Invoke P7ZIP to extract archives and images with “7z x”.
![Do you need to keep dmg files after install windows 10 Do you need to keep dmg files after install windows 10](/uploads/1/3/4/3/134385895/169169683.jpg)
Notice that 7z extracted three files: “0.ddm”, “1.Apple_partition_map”, and “2.hfs”. To actually get to the files, we’ll need to run 7z again on “2.hfs”.
We picked “2.hfs” because it was the biggest of the three, meaning it was probably the one with the data. Simple but effective logic. After a few moments, you should have a folder called “Firefox” with all of the files from the original DMG.
