[Max.1974]

 

 

DMG Creator 

This tool creates a macOS DMG installer with a drag-and-drop window (your app on the left, Applications folder on the right).

---

📦 Requirements

• macOS (tested on 10.13+ up to Sonoma/Tahoe).

• No extra dependencies (uses built-in hdiutil and osascript).

---

▶️ How to Use

1. Prepare your app
   Place your .app bundle (or any file/folder) in a convenient location (e.g., Desktop).

2. Run the DMG Creator

   • Double-click the create-dmg executable.

   • The script will open in a Terminal window automatically.

3. Drag & Drop your app
   When prompted, drag your .app file into the Terminal window and press Enter.

4. Choose the DMG name

   • Type the desired name (without extension).

   • If left empty, the app’s name will be used.

5. Wait for Finder setup
   A temporary DMG will mount and open in Finder.
   You’ll see your app icon and an Applications shortcut side by side.

6. Confirm layout
   When the DMG window looks correct, return to Terminal and press Enter.

7. Done 🎉
   The final DMG will be created on your Desktop.
   Example:

   DMG created at: /Users/YourName/Desktop/MyApp.dmg

🧹 Cleanup

All temporary files are automatically removed after the DMG is created.

Nice, But What Do You Do With The DMG Once It's Created?

Hi @STLVNUB This application aims to save an app or a folder into a DMG for distribution. It’s widely used to package EFI or any file you want to preserve, unlike a ZIP.

It makes things much easier, especially for those who often create apps and want to distribute them.

@STLVNUB 

I’m sorry my friend, for the delay.

To change the icon, you need to open the application with Command + I, then press Command + C (copy) on the icon you want.

After that, open the folder where you want to place the icon in the same way, and press Command + V to paste it into the empty icon field.

And you also can use the Image2Icon app for this.
