Flutter is currently on a mission to become a true “write-once, run anywhere” technology. iOS and Android platforms are extensively supported and it’s already possible to build macOS applications using Flutter.
DMGConverter is a disk image (.dmg,.cdr,.iso) creation and conversion tool which is simple and easy to use. It is a very useful tool for the collective processing of more than one file and every folder, and it can deal with all the fundamental processing with the drag & drop of the file/folder.
ℹ️ This post solves a very technical issue – if you’re interested in learning more about Flutter and why to use it, this article provides a higher-level overview and explains why we are building our AI-assistant with Flutter.
Building and running a macOS application with Flutter has become quite easy in the last few months. Unfortunately, the tooling around Flutter Desktop applications still lacks some essential features – but be assured that the maintainers of Flutter are already working on most of them.
Preferred HandBrake settings: Leave Sizing, Aspect Ratio. Use filters or optimal settings for the type of video you’re working with. Some encoders, like h264 in HandBrake, offer special settings and filters geared towards the type of movie or video you’re working with. Acadience® is a proprietary name referring to the work of Roland Good, Ruth Kaminski, and Dynamic Measurement Group, Inc. The intent of DMG is to make the current Acadience Reading assessment tools and materials downloadable from this website (the “Acadience Reading Materials”) available to schools, school districts, and multi-district agencies for the limited purposes,. An EXE or DMG file will be included with the installer. The name of the file will be such as setup.exe. Otherwise, the user can launch the respective files from the delivered content. Next, choose the option Install. There will be a drop-down menu for the preferred language. The user can choose the desired language.
Shipping a Flutter Desktop application to customers
One of the essential features currently missing is the capability to build a macOS Installer (usual a .dmg file) for distribution. By default, Flutter builds a .app file, which can be executed straight away:
Building a .dmg with Flutter
But what, if you would like to distribute an installer?
There is a great project called “create-dmg” out there, which can be installed using Homebrew (refer to the project’s README for other setup methods):
To give it a try, switch to the /build/macos/Build/Products folder after building your macOS application.
Customizing your installer
To make your installer more fancy, you can customize the volume name, volume icon, and installer background. You just need to fiddle with the icon placement and text size and you’ll end up with a few command lines:
The script automatically prepares the DMG installer with the desired settings. Don’t be spooked by some windows automatically appearing in the process:
Even more fancy with Retina support
By default, the background image does not support retina resolutions and might look a bit blurry. Fortunately, it’s possible to use a TIFF image instead of PNGs / JPGs. Just create a @2x version of your background image with twice the resolution. On macOS you can use tiffutil to create a retina-ready background image for your installer:
There are a few more options to consider when using create-dmg. For example, you can attach your own EULA / license. Keep in mind, that this manual step (of creating a DMG installer) might be obsolete in future versions of Flutter. But for today, this enables you to get up and running with your own, distributable Flutter desktop application in no time.
Learning how to create a bootable macOS installation disk can be helpful in a variety of situations. Rather than download and install a new OS from Apple's servers each time, it can be used for multiple installations on different machines. It can also help in situations where the operating system is corrupted or installation from app store shows errors.
To create a bootable macOS installation disk, you have to burn the DMG file to a USB drive as CD/DVD is not available for Mac computers. Here's how to do it from text commands and using a purpose-built software called WizDMG. You will first need to download the DMG file for the macOS version you wish to install. For example, if you want to create a bootable macOS Mojave installer, you will need the DMG file for macOS Mojave. Once the file has been downloaded to your PC, you can proceed with one of the bootable disk creation methods shown below.
Method 1: How to Create Bootable USB Installer for Mac via Commands
macOS (formly named Mac OS X) is just a variant of popular Unix based operating system. This means a lot of daily and advanced tasks on Mac can be done via text commands such as creating bootable USB installer for Mac. However, this could be a lot of challenges if you had no clue about commands and I suggest taking a look at the other solutions in this post to avoid messing up the computer with the wrong commands.
Step 1. Search macOS name in app store (Mojave, High Serria, EI Capitai). Click 'Get' button to download the installer image on your Mac. The downloaded file will be located in Application folder.
Step 2. When the download is completed, the installation windows opens automatically, just close the window and go to Application folder. You will find a file started Install, such as Install macOS Majave.
Step 3. Now connect an external flash drive with more than 16G free space. And backup the data in that USB drive as the installer erase all content from it. Open Disk Utility app and format the USB drive with APFS or Mac OS Extended.
Step 4. Open the Terminal app and copy-and-past the following commands to make a booatble USB installer from macOS image:
For Majove: sudo /Applications/Install macOS Mojave.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume
For High Serria: sudo /Applications/Install macOS High Sierra.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume
For EI Capitan: sudo /Applications/Install OS X El Capitan.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume --applicationpath /Applications/Install OS X El Capitan.app
Step 5. Input the admin password when being prompted. And wait for the booatable disk being created. When it is done successfully, you will receive a message shown in above screenshot.
Unconfortable with text commadns and prefer doing it in a simple way? The second suggestion is more user friendly!
Method 2: How to Make Bootable USB from macOS with WizDMG
WizDMG fills a huge gap in Windows not supporting DMG files. It is a desktop utility supporting Windows and Mac. It allows you to directly burn DMG files to disk in order to create a bootable macOS Mojave installer or a boot disk for any macOS version.
WizDMG offers an intuitive interface with no clutter and full functionality to handle DMG files. Apart from burning such disk image files to DVD/CD or USB, it also gives you edit options where you can add and remove files from within the DMG file, rename DMG files and even create DMGs from files and folders on your desktop. This software application has been created for novice users as well as experts. It is easy to use, has a very high burn success rate and will help you create a bootable macOS installer in no time. Follow the instructions below:
Step 1Install WizDMG
Download WizDMG from the official website and install it on your PC. Launch the program and select the 'Burn' option in the main interface.
Step 2Create Bootable USB from macOS Install Image
Click on Load DMG to import the macOS installation file into the application. Insert a USB (16G free space) and click on the 'Burn' button next to the appropriate media type.
The important thing to remember here is that you now know how to create a macOS installer in Windows. There aren't a lot of options out there because of the compatibility issues between Mac and Windows environments. That means converting DMG to ISO and back again to DMG leaves the door open for corrupted files and incorrectly burned bootable media, which defeats the whole purpose because it might not even work in the end.
Method 3: Create macOS High Serria/Mojave Bootable USB on Windows 10/7
Another way to create macoS bootable disk on Windows is using a tool called DMG2IMG along with Windows command prompt. It requires a bit of a workaround, but even novice users can learn to burn a DMG file to a disk to create bootable media for a macOS installation. Just make sure you follow the instructions below carefully.

Step 1. Download DMG2IMG and install it in your Windows PC. Open File Explorer and go to the folder containing the DMG2IMG program, then right-click and select 'Open command windows here.'
Step 2. Type the following command and hit Enter: dmg2img [sourcefile.dmg] [destinationfile.iso]
Step 3. Now that the DMG file has been converted to ISO format, you can use the following command to burn it to a disk. Before that, insert a disk into the optical drive: isoburn.exe /Q E: 'C:UsersUsernameDesktopdestinationfile.iso'
Step 4. This command utilizes the Windows native disk image burner to burn the ISO to the disk in your optical drive. The ISO file can't be used directly in macOS, but it can be mounted as a virtual drive. Once you do this, you can convert it back to DMG using Disk Utility in Mac. You can then use this as your bootable macOS installer.
As you can see, this is a bit of a workaround because DMG files aren't natively supported in Windows. Likewise, ISO files aren't fully supported in macOS.
