The threat extends beyond accidental errors. When AI writes the software, the attack surface shifts: an adversary who can poison training data or compromise the model’s API can inject subtle vulnerabilities into every system that AI touches. These are not hypothetical risks. Supply chain attacks are already among the most damaging in cybersecurity, and AI-generated code creates a new supply chain at a scale that did not previously exist. Traditional code review cannot reliably detect deliberately subtle vulnerabilities, and a determined adversary can study the test suite and plant bugs specifically designed to evade it. A formal specification is the defense: it defines what “correct” means independently of the AI that produced the code. When something breaks, you know exactly which assumption failed, and so does the auditor.

macOS completes the MacBook Air experience, with incredible features and built-in apps, such as Safari, Photos, Messages, and FaceTime, that enable users to get even more done. With macOS Tahoe, a beautiful design with Liquid Glass lets users personalize their Mac in new ways with color options for folders, app icons, and widgets.6 Apple Intelligence adds powerful features with groundbreaking privacy at every step — including Live Translation in Messages to communicate across languages, updates in Reminders that automatically categorize the most relevant actions, and more powerful Shortcuts actions that tap directly in to Apple Intelligence models to create automations, such as extracting information from a PDF and adding key details to a spreadsheet.3 Continuity features include the Phone app on Mac, which lets users relay cellular calls from their nearby iPhone, and they can stay on top of notifications with Live Activities, which open in iPhone Mirroring so users can take immediate action right from their Mac.7 Additionally, for video calls, a new Edge Light effect provides a pleasing fill light to evenly illuminate a user’s face in any lighting condition.
