EasyDMG by Jeff for Mac

After setting EasyDMG as your default app for opening DMGs (instructions below - but it's just "click the button"), opening any DMG will automatically:

• Mount the DMG
• Copy the app to /Applications folder
• Open Applications and highlight the new app, ready for you to run it. Or open the app directly
• Unmount the DMG
• Trash the DMG (optional via Settings)

Features

• It's EASY!: Set EasyDMG as your default DMG handler and forget about it.
• It's simple: After setting as your default, the app only runs when opening a DMG. Doesn't take up space in your dock or menubar, it's gone until you need it
• It's fun: Enjoy the hamster progress bar if enabled 🪄
• It's native: Built with Swift for MacOS, it's quick and seamless
• Flexible settings: Choose between progress window, notifications, or silent mode
• Save disk space: Optionally moves DMGs to Trash after successful installation. No more old DMGs sitting in your downloads folder!
• Safety third: If EasyDMG encounters anything unusual (license agreements, multiple apps, pkg installers), it opens the DMG and lets you handle it manually. It only automates the simple, common case.
• Automatic updates: Built-in Sparkle integration for easy updates

If there's anything weird, like a .pkg or an installer, EasyDMG simply falls back to manual control and lets you handle it. 98% of the time (according to rigorous studies, obviously) a DMG is simple and is completely handled in a second. No more dragging the little app icon into the little folder, like a peasant.
