+dtrace_externalMethod.py
+
+A script to trace kernel functions related to IOConnectCallMethod using DTrace.
+Prints the PID, full executable path, demangled kernel function name, and user
+call stack for each event.
+
+Requirements:
+    - Must be run as root (sudo).
+    - System Integrity Protection (SIP) may need to be disabled for full
+      DTrace functionality on macOS.
+
+Usage:
+    1. Make the script executable:
+        chmod +x dtrace_externalMethod.py
+    2. Run with sudo:
+        sudo ./dtrace_externalMethod.py
+    3. Press CTRL+C to stop tracing gracefully.
+
+Output:
+    For each relevant kernel call, prints:
+        - PID
+        - Executable path
+        - Demangled kernel function name
+        - User call stack
+
+Graceful termination is handled via signal (SIGINT/SIGTERM).
