DMG Canvas 4.2.3 is a visual disk image design tool for the Mac. It gives developers the ability to create professional, branded DMG files with custom backgrounds and layouts, one-click code signing, built-in notarization, and automation support for repeat software releases.

Download DMG Canvas 4.2.3 Overview

DMG Canvas is a disk image design and creation tool for macOS. It is created for developers, designers and software distributors who want to package apps in a branded, polished way before release. DMG Canvas gives you a real canvas – a visual editor where you can drag and drop your app icon, background image, other files and text, position them as you like, and then export them into a complete, ready-to-distribute disk image, instead of manually editing the appearance file of a disk image, one file at a time. Besides layout design, DMG Canvas also handles the technical aspects of professional distribution: one-click code signing of a disk image, so that it is trusted as safe by both macOS as well as end-users, and notarizing the disk image and its contents to satisfy Apple’s post-Catalina security requirements (this requires the installation of Xcode). The app also supports Retina-ready design elements, Dark Mode-aware backgrounds and automation – including the ability to generate an Xcode Post-Archive build script, or using Apple’s Shortcuts app to automatically build a disk image as part of a release pipeline. Version 4.2.3 continues to polish the app. It’s about 18.5 MB and can be installed directly or with Homebrew (brew install --cask dmg-canvas). DMG Canvas requires macOS 11.0 or later. Disk images created with DMG Canvas will however work with OS X 10.4 and later, regardless of the macOS version it was built with.

Key Features

Visual Editor workspace Design the entire appearance of a disk image right on a canvas – put the app icon, a background, other files and text exactly where they should be when a user opens the mounted disk image. Custom Backgrounds and Icons Placement You can use a graphic editor to create a background for the disk image window . The size and position of this background can be adjusted by hand . You can also use a solid color rather than an image and you have control over the size of icons within the window . Support Retina Ready Designs If you target OS X Lion and later, you can add crisp, high-resolution Retina images and text to disk images and they will look sharp on modern high-DPI Mac displays. One Click Code Signing Code sign a disk image in one click, satisfying macOS Gatekeeper requirements and reassuring the OS and end users the disk image is safe. Built-In Notarization Notarize the disk image and its contents directly within the app to meet Apple’s post-Catalina security requirements, the process requires Xcode to be installed on the building machine. Dark Mode Aware Backgrounds When using the None/Default background option, the disk image window automatically adapts its appearance to the user's system setting — dark gray background with white file names in Dark Mode, versus the standard light appearance otherwise. Maximum Backward Compatibility Disk images built with DMG Canvas are carefully constructed to look and work correctly all the way back to OS X 10.4, regardless of which macOS version was used to create them. Automation Support Automate disk image creation with the Shortcuts app on Apple, or create an Xcode Post-Archive build script to automatically build a disk image as part of an existing release workflow. Install Homebrew Support DMG Canvas installs directly with Homebrew in a single cask command, fitting neatly into a developer’s existing command line tooling.

Step 5: Include Retina-Ready Assets Make sure to provide high resolution Retina versions of your background and text elements so they will look crisp on modern displays. Step 6: Set up Dark Mode Behavior If using the None/Default background option, confirm the disk image window will correctly adapt its appearance between light and dark system settings. Step 7: Signing the Diskimage Apply code signing with a single click before distribution, ensuring compatibility with macOS Gatekeeper and building trust with end users. Step 8: Notarizing the Disk Image Apple security requirements in macOS Catalina, using built-in notarization process (install Xcode).
