DMG Canvas lets you create and build disk images using the slick WYSIWYG designer. Simply drag and drop your files into place, add text, images, and change the background image for the mounted window, and you can even add stylized license agreements to your disk images, which — believe us — is a massive pain otherwise. A DMG file is Apple's equivalent of an ISO installation file or disk image. It usually contains all the information required to install a program on a Mac computer running Mac OS X or macOS. It is also a container to hold macOS installation image. If you want to create a bootable macOS bootable disk, the first step is to burn DMG to USB or DVD. Make a folder with the files your DMG will contain. Open Disk Utility (It's in /Applications/Utilities/) Go to File New New Image from Folder (Cmd + Shift + N) Choose the folder containing you files. To create a bootable USB drive from a DMG file on Windows, you will need to have the right utility. That's because DMG is not native on Windows. It is the Mac equivalent of an ISO file that has been in use since Apple transitioned from the IMG format with Mac OS X. A DMG file, like ISO, can be used to install macOS operating system or Mac apps.
First, review this introductory article: Create a bootable installer for macOS. Second, see this How To outline for creating a bootable El Capitan installer. Simply replace the Terminal command with the one from the preceding article by copying it into the Terminal window. You will need an 8GB or larger USB flash drive that has been partitioned and formatted for use with OS X.
Drive Partition and Format
- Open Disk Utility in the Utilities' folder.
- After Disk Utility loads select the drive (out-dented entry with the mfg.'s ID and size) from the side list.
- Click on the Erase tab in the Disk Utility toolbar. Name the drive, 'MyVolume'. <---- IMPORTANT!
- In the drop down panel set the partition scheme to GUID. Set the Format type to Mac OS Extended (Journaled.)
- Click on the Apply button and wait for the Done button to activate. When it does click on it.
- Quit Disk Utility.
