macOS Network Diagnostics & Information Tool Bash Script

This Bash script collects detailed network information on a macOS system by querying system utilities (like route, ifconfig, and ipconfig) and formatting the output with colored text for easy reading. It reports data such as the default gateway, active interface, IP address, subnet mask, broadcast address, MAC address, DNS servers, public IP, and average ping latency
