Implement a prank that changes the desktop background to a goat image using an Arduino USB dongle. The image should be downloaded from a remote server using curl or wget and set as the wallpaper on macOS.

Example Implementation

void changeDesktopBackground() {
    // Command to download the goat image
    Keyboard.print("curl -o /tmp/goat.jpg http://example.com/goat.jpg");
    Keyboard.press(KEY_RETURN);
    delay(1000);

    // Command to change the desktop background
    Keyboard.print("osascript -e 'tell application \"Finder\" to set desktop picture to POSIX file \"/tmp/goat.jpg\"'");
    Keyboard.press(KEY_RETURN);
    delay(1000);
