To create a Ducky Script (DS) payload for macOS that opens TextEdit and types a message, you need to define a sequence of actions. Here's a simplified overview of the steps:

1. Set Attack Mode: You begin by setting the attack mode for your Rubber Ducky USB device to emulate a keyboard.

2. Introduce Delays: Use DELAY commands to give the system time to respond between actions, ensuring that each command is executed smoothly.

3. Open TextEdit: Use the command to invoke Spotlight (COMMAND SPACE), type TextEdit.app, and then hit ENTER to open the application.

4. Write Text: After opening TextEdit, use STRING to type messages, and ENTER to create line breaks when necessary.

5. Test and Adjust: After deploying the payload to the Rubber Ducky, test it to see if it behaves as expected and make adjustments if necessary, such as changing delay times and ensuring no unwanted dialogs appear.

Here’s a refined version of the payload based on your explanation:

ATTACKMODE HID VID_05AC PID_021E
DELAY 1000
COMMAND SPACE
STRING TextEdit.app
ENTER
DELAY 250
COMMAND n
DELAY 1000
STRING Hell o' World
ENTER
DELAY 1000
STRING Duck you, 
STRING you ducking duck!
ENTER
ENTER
STRING Especially you. 
STRINGLN Yes, you

This payload addresses the initial requirements while enhancing stealth by avoiding unnecessary setup dialogs.
