The automated tracking mechanism builds a detailed personal profile across Intel and Apple silicon hardware by cross-referencing activity in Contacts, Mail, Photos, and Messages. Operating out of the local IntelligencePlatform directory, the system correlates everything from calendar attendance to emergency contacts within dozens of plaintext files. To help users review this undisclosed data collection, researchers developed an open-source tool called iKnow.

Anatomy of Apple's Personal Knowledge Graph
Every Mac since macOS 13 (2022) ships a pair of daemons whose only purpose in life is to build a graph about who you are, who you know, how those people are related to you and to each other, how you communicate with them, where you go, what you do and when. In this post, we look into how this system works and give you a tool to peek into your own graph.
The position
A family fork: one knight on e2 attacks White's king, queen, rook and bishop at once. White's pieces are the household the graph is about; the knight is the store, one move from every one of them. White's own last move, 18.e3
, emptied the square it stands on. White is in check and has one legal reply, Kh1
; then the knight takes the queen. The check falls on the one who accepted the terms. What is lost is someone else.

Armed forces across the globe are heavily upgrading rotary-wing aircraft to deliver precision strikes from extreme standoff distances. By equipping platforms with advanced, extended-range munitions, military planners are blurring the conventional lines dividing traditional aviation, unmanned systems, and cruise weapons. This evolving doctrine significantly increases survivability by letting crews strike valuable land and naval targets well beyond hostile defensive perimeters.
The FIA-certified milestone establishes a high-performance benchmark for battery-powered vehicles, demonstrating that modern electric platforms can achieve extreme velocity previously dominated by conventional supercars. The run serves as an international technical showcase for the company's proprietary battery chemistry and active chassis management systems.
