macOS Sequoia 15.7.3 & Sonoma 14.8.3 Security Updates Released

Apple has released important security updates for two recent macOS versions. macOS Sequoia 15.7.3 and macOS Sonoma 14.8.3 are now available. These updates focus solely on security enhancements and include Safari 26.2. They contain no new features. Apple also separately released the macOS Tahoe 26.2 update, but the company cautions that Tahoe remains “flawed and buggy,” making it difficult to recommend.

How to Install the Updates (And Avoid macOS Tahoe)

It’s crucial to back up your Mac with Time Machine before proceeding. This protects your data and allows easy reversion if needed.

  1. Open the Apple menu and go to “System Settings.”
  2. Navigate to “General” and then “Software Update.”
  3. Ignore the prominent macOS Tahoe 26.2 banner at the top of the screen.
  4. Look below for the macOS Sequoia 15.7.3 or macOS Sonoma 14.8.3 update and select it.

Important Warning: If you click the (i) info button, the system may auto-select macOS Tahoe 26.2. You must manually uncheck Tahoe and ensure your preferred Sequoia or Sonoma update is checked. Double-check your selection to avoid installing the problematic Tahoe release.

The installation will require a system reboot.

Broader Apple Ecosystem Updates

Alongside these Mac updates, Apple has also released:

  • iOS 26.2 for iPhone
  • iPadOS 26.2 for iPad
  • watchOS 26.2, tvOS 26.2, and visionOS 26.2
  • iOS 18.7.3 and iPadOS 18.7.3 for users avoiding the iOS 26 update path

Prioritize Security, Avoid Tahoe

Users on macOS Sequoia or Sonoma should install these security-focused updates promptly. However, careful navigation of the Software Update screen is essential to avoid accidentally updating to the reportedly unstable macOS Tahoe. Always ensure your Mac is backed up before applying any system update.
