Apple has rolled out two critical security updates after uncovering zero-day vulnerabilities targeting Intel-based Mac computers.

In a disclosure posted Tuesday, the company detailed its discovery of the flaws and the rapid fixes implemented to protect Mac users. These zero-day bugs — so named because they were exploited before Apple could address them — prompted the release of bug patches for iOS devices and a dedicated macOS software update.

The vulnerabilities stem from Apple’s WebKit and JavaScriptCore, which drive Safari and render web content.

Regardless of the source, the priority for Apple users is clear: update your devices immediately to ensure they’re running the latest software. Here's how:
