DropDMG makes it easy to create a professional disk image for your app. Disk images pack entire folders or disks into a single compressed file, either for transport across the Internet or simply for backup or archival. They are Apple's preferred format for distributing Mac software and the only archive format whose contents you can directly access in the Mac Finder—no extraction or third-party software required.

Supported Operation System
• macOS 10.13 or later
• Apple Silicon or Intel Core processor
