In the early hours of December 13, 2025, Apple rolled out its 26.2 updates across all platforms, including iOS, iPadOS, macOS, watchOS, tvOS, and visionOS. The macOS Tahoe 26.2 update brings the Edge Light feature for video calls in low-light conditions, adds alarm support to the Reminders app, improves Podcasts, and updates AirDrop settings.
At the same time, Apple released macOS Sequoia 15.7.3 (alongside macOS Sonoma 14.8.3) for Macs that cannot upgrade to the latest macOS version. This update is primarily focused on security fixes and system stability improvements, rather than new features.

-

This update ensures that Macs running macOS Sequoia remain secure and stable, even without the latest macOS features.
