DMG files make app installations on macOS a lot quicker and easier. However, there have been several reports from users about the .dmg file not opening on Mac. There are different versions to this error, but the end scenario is the same: for some reason, users are unable to open the .dmg file on Mac. This guide will discuss why some users have trouble opening a DMG file and how to resolve this issue.
Installing a DMG file on Mac should be as easy as double-clicking the file and dragging the app to the Applications folder. However, the process is not as smooth for some Mac users because they are not able to open the DMG file to start with. According to user reports, the download process was completed and there were no issues with unzipping. But when it comes to opening the unzipped files, nothing happens. Some users who encounter this issue get the resource temporarily unavailable error while others noted no activity happening no matter how many times the file is clicked.
When the user tries to open it, either the options are grayed out or nothing happens when any of the options are clicked. This error has caused the affected Mac users to be frustrated. The users who encountered this error tried to redownload the file using a different Mac and the DMG file seems to be working fine, which means that the problem lies with the device itself. But what causes DMG files to not open on Mac?
Some users noted that they cannot open the .dmg file on Mac after updating to Catalina, but there are also those who encountered this error when running an older version of macOS. This means that the problem is not unique to Catalina but it is something that affects the entire macOS system.
If the right-click menu is grayed out or nothing happens when you click any of the Open With options, you can try mounting the file using Terminal instead. Drag the file to the Desktop and follow the steps below:

DMG file is used by Apple Mac OSX Disk Image files. Mac OS X natively support DMG files with the bundled AppleDisk Utility, and can mount and treat them as though they are physical diskvolumes. Mac OS Classic originally used the IMG file format for the samepurposes, though this has now been superseded by DMG format.
DMG files are similar in nature to otherdisk image files such as ISO in that they contain a folder and file structurewhich can be mounted and treated like a physical volume. As well as browsingthe contents of a DMG file, it can also be used as the source to create CD orDVD copies. However, DMG files can use a variety of different file systemsincluding HFS, HFS+, Linux and Fat32, and are usually compressed, which maymake them incompatible with other software on other operating systems such asWindows. DMG files are often used to distribute software in the same manner asan EXE file is used for the Windows platform, and may be password protected toprevent unauthorized users mounting and using the image.
You can open DMG file in Mac OS Xusing the Apple Disk Utility, which is bundled as part of the operating system.However, the DMG file format is new to OS X and as such is not compatible withprevious versions of Mac OS. DMG files are specific to Mac OS X, though can beopened in Windows using an application such as TransMac. Additionally, toolssuch as IsoBuster and DMG2ISO can be used to convert DMG files to more recognizableformats such as File extension ISO or File extension BIN, which can be opened using a wide range ofapplications or burnt straight to disc using software such as Roxio or Nero.
Full support for the normal zip format, with additional support for AES encryption, Zip64 extensions for large files, Mac OS extensions of many different kinds, and several unusual compression methods. Can also extract .EXE self-extracting files using Zip.
This format is also used by many other Microsoft formats, meanings that you can use The Unarchiver to extract internal data from DOC and PPT files, and others. There is probably no reason to do this, but you can.
I downloaded a dmg file by canon for their digital photo professional software (from their offical website here). I am running Mac OS Catalina 10.15.6 on a MacBook pro and have an eos 70D camera. The file mounts, but when i then try and open the mounted installation file it seem to crash before opening. It starts extracting the files and I see an icon open for a split second down next to the trash icon but then it disappears completely and nothing actually opens properly. I have tried looking everywhere for info online, but it's all directed towards how to actually mount the file - but in my case it seems to be mounting just fine. I've tried different canon downloads too (eg eos utility etc) and the same thing happens. I've also downloaded the files multiple times and tried different ways of mounting them but still experiencing the same problem. I have no idea what's going on!
You may need to reinstall macOS over top of itself in case some system files have become corrupted or damaged. You can boot into Recovery Mode using Command + R where you can select to "Install macOS". Or you can create a bootable macOS USB installer. This should not affect your data, but you should definitely make sure you have a good backup first just in case something goes wrong.
With WinZip for Mac 2.0 or later, you can right-click (or press CTRL and click) your saved Zip files and use the Context Menu to unzip them. Click on Services at the bottom of the Context menu, then choose Unzip, Email as Zip File and Add to Zip.
If you press command and click on the item in the download bar, it shows the item in the finder. At that point, simply pressing command-O (or double-clicking the dmg file) will mount it and open it in a new window in the foreground.
With WinZip for Mac 2.0 or later, you can right-click (or press CTRL and click) your saved RAR files and use the Context Menu to unzip them. Click on Services at the bottom of the Context menu, then choose Unzip.
DMG is a file of Apple Disk Image. The Apple Disk Images are disk image files commonly used by the Mac OS X operating system. When opened, an Apple disk image is "mounted" as a volume within the Finder. Several Apple proprietary disk image formats can be used to create these images, including the Universal Disk Image Format (UDIF) and the New Disk Image Format (NDIF). Apple disk images usually have the .dmg file extension.
Apple disk images allow secure password protection as well as file compression and hence serves both security and file distribution functions; they are most commonly used to distribute software over the Internet.
Universal Disk Image Format (UDIF) is the native disk image format for Mac OS X. Disk images in this format typically have a .dmg extension. New Disk Image Format (NDIF) was the previous default disk image format in Mac OS 9, and disk images with this format generally have a .img (not to be confused with raw .img disk image files) or .smi file extension. Files with the .smi extension are actually applications that mount an embedded disk image, thus a "Self Mounting Image", and are intended only for Mac OS 9 and earlier. A previous version of the format, intended only for floppy disk images, is usually referred to as "Disk Copy 4.2" format, after the version of the Disk Copy utility that was used to handle these images. A similar format that supported compression of floppy disk images is called DART. Apple disk image files are published with a MIME type of application/x-apple-diskimage.
Different file systems can be contained inside these disk images, and there is also support for creating hybrid optical media images that contain multiple file systems. Some of the file systems supported include Hierarchical File System (HFS), HFS Plus, File Allocation Table (FAT), ISO9660 and Universal Disk Format (UDF).

Again, just because you can extract a DMG file in Windows, or even convert a DMG to a Windows-readable format, doesn't always mean that the contents of the DMG file will suddenly become compatible with Windows. The only way to use a Mac program or a Mac video game in Windows is to download the Windows-equivalent version. If there isn't one, then neither converting nor extracting a DMG file will be of any use.
Drive redirection is supported for remote resources, so that you can save files created with a remote application locally to your Mac. The redirected folder is always your home directory displayed as a network drive in the remote session. 2ff7e9595c
