DMG Canvas For Mac

Disk images are among the most popular app distribution methods on macOS, and developers need to create a new one for each release as efficiently as possible. If they can make it look great in the process, that's just another way for their software to stand out.

DMG Canvas is an app that can help you out in a number of ways. It allows you to design high-quality disk image layouts using backgrounds and text, as well as notarize and code sign your DMGs. What's more, it supports automation to speed up the creation of disk images for future releases.

As the app's name implies, it presents you with a canvas where you can place an app and other files, a background, images, and text. There are many tools to help you arrange and customize them, so it's pretty easy to get things to look just right.

Everything can be personalized, from the window's dimensions to the position and size of various elements, fonts, colors, and alignments. Most of the work is done with drag and drop, so it takes no expertise to speak of.

If you want users to agree to a license before viewing the disk image's contents, you can add one for each of the supported languages.

DMG Canvas also allows you to notarize disk images, which is a requirement starting with macOS Catalina in order to ensure applications are clean. You can easily notarize the image and its contents, provided Xcode is installed.

To ensure Gatekeeper doesn't enable extra security features for your disk image, it's also a good idea to code sign your DMGs, which this app can help you with.

Last but not least, DMG Canvas allows developers to speed up disk image creation using the integrated dmgcanvas command-line tool. This can be added to your build workflow so that a DMG file will be created whenever you build an application in Xcode.

With all that in mind, DMG Canvas really is an excellent choice for developers. It offers everything you need to prepare an app for distribution, and it is surprisingly easy to use.
