Apple Releases Security Update: Patches for iOS Zero-Day and macOS

Apple released security updates for iOS, macOS, and more to address a new zero-day vulnerability, reinforcing its commitment to user safety.

Patch updates

On January 27, 2025, Apple released critical updates for iPhones, iPads, Macs, Apple Watches, Apple TVs, Vision Pro, and Safari to address a zero-day vulnerability and other security issues.

Key updates include:

iOS 18.3 & iPadOS 18.3: Fixes a zero-day flaw; urgent update for supported devices.
macOS Sequoia 15.3, Sonoma 14.7.3, Ventura 13.7.3: Patches for system stability and security.
watchOS 11.3: Security enhancements for Series 6 and later.
tvOS 18.3 & visionOS 2.3: Performance and security updates.

Apple’s updates address active exploits targeting vulnerabilities discovered in late 2024. These flaws allowed attackers to bypass memory protections, affecting devices with outdated software. Users on older iOS, macOS, or Safari versions were at high risk.

The rollout highlights Apple’s use of Rapid Security Responses to quickly fix critical vulnerabilities without full software updates.

Apple recommends enabling automatic updates for device security. To manually update:

iPhone/iPad: Go to Settings > General > Software Update.
Mac: Open System Settings and select Software Update.
Apple Watch: Use the Watch app on your iPhone, then go to General > Software Update.
Apple TV: Go to Settings > System > Software Updates.
