Finding a bootable macOS DMG file that actually works can be a headache. Many DMG files floating around the internet are either corrupted, incomplete, or just won’t boot. That’s why we’ve put together a list of fully tested and verified macOS DMG files to save you time and frustration.
Heads up! Don't grab the DMG file straight from Apple—it won’t boot your Mac. It’s just a container for the .pkg installer, meaning you’ll have to extract it manually. And to make things worse, you can’t even do this on a Windows PC.
Our team has personally tested these files to ensure they are bootable, reliable, and ready to use for creating a macOS installation USB. Whether you’re reinstalling macOS, setting up a virtual machine, or repairing your system, you can trust these downloads to get the job done. The table below lists all the available bootable DMG files for different macOS versions.
