Apple has released the first beta of macOS Tahoe 26.3 to registered developers and public beta testers, marking the beginning of the testing cycle for what is expected to be a stability and security-focused update. The public release is anticipated to arrive in late January 2026.
The first developer beta (build 25D5087f) was released on December 15, 2025, followed by the public beta on December 17. This update comes just days after Apple released macOS Tahoe 26.2 to the public on December 12, maintaining the company's rapid update cadence.
How to Install the macOS Tahoe 26.3 Beta
For Developers:
- Enroll in the Apple Developer Program at developer.apple.com

- Open System Settings > General > Software Update
- Select the beta update when it appears
For Public Beta Testers:

What's New in macOS Tahoe 26.3
Unlike the previous macOS Tahoe 26.2 update which introduced the Edge Light feature for video calls and other notable improvements, version 26.3 appears to be a maintenance release. As of the first beta, no new features have been discovered by developers or beta testers.
This aligns with Apple's typical pattern for ".3" updates, which often focus on:
- Bug Fixes: Addressing issues reported by users since the 26.2 release
- Security Patches: Resolving vulnerabilities discovered through Apple's security research and bug bounty program
- Performance Improvements: Optimizing system resources and enhancing stability
- Compatibility Updates: Improving support for third-party hardware and software
Expected Public Release Date
Based on Apple's historical release patterns, macOS Tahoe 26.3 is expected to launch to the public around the week of January 26, 2026. Specifically, Monday, January 26 is considered the most likely release date.
This timeline is supported by previous years:
- iOS 18.3 was released on January 27, 2025
- iOS 17.3 was released on January 22, 2024
- Apple typically follows a 4-6 week cycle between point releases
The update is expected to be released simultaneously across all Apple platforms, including iOS 26.3, iPadOS 26.3, watchOS 13.3, tvOS 26.3, and visionOS 3.3.
Beta Software Warning
Beta versions of macOS are pre-release software that may contain bugs, stability issues, and compatibility problems. They are intended for:
- Registered developers testing their apps
- Public beta testers willing to report issues
- Testing on secondary, non-critical devices
Do not install beta software on your primary work Mac or any device you depend on for critical tasks.
Context: Recent macOS Tahoe Updates
The macOS Tahoe 26.3 beta follows the release of version 26.2 on December 12, 2025, which introduced several notable features:
Edge Light Feature
The flagship feature of macOS 26.2 was Edge Light, which uses the Mac's display to illuminate your face during video calls in low-light conditions. On newer Macs from 2024 and later, the feature can activate automatically and offers customizable light width and temperature settings.
Other 26.2 Improvements
- Automatically generated chapters in podcasts with embedded links
- Improved filters in the Games library and in-game challenge updates
- Support for connected game controllers
- Navigation improvements in Apple News
- More flexible tables in Freeform
- Favorite Songs playlist in Apple Music Top Picks
Critical Security Fixes
macOS Tahoe 26.2 also addressed 46 security vulnerabilities, including two WebKit zero-day exploits that Apple confirmed were actively exploited "in an extremely sophisticated attack against specific targeted individuals."
What About Older macOS Versions?
Apple continues to support users who haven't upgraded to macOS Tahoe with security updates for older operating system versions:
- macOS Sequoia 15.7.3: Released December 12, 2025 (security-only update)
- macOS Sonoma 14.8.3: Released December 12, 2025 (security-only update)
These security updates addressed 25 vulnerabilities in Sequoia and 21 in Sonoma, including the same critical WebKit zero-day exploits patched in Tahoe 26.2.
Should You Stay on Sequoia or Upgrade to Tahoe?
Some users have reported stability issues with macOS Tahoe and have chosen to remain on Sequoia. If you're considering upgrading:
- Check that all your critical apps are compatible with Tahoe
- Read user reports from people with similar Mac models
- Wait for the 26.3 release if you want a more stable version
- Remember that Sequoia still receives security updates
Note: When updating from Sequoia, be careful in Software Update - Apple displays an aggressive Tahoe upgrade banner at the top. Look below it to find Sequoia security updates if you want to stay on Sequoia.
Testing and Feedback
Apple encourages beta testers to report bugs and issues through the Feedback Assistant app, which is pre-installed on beta versions of macOS. Key areas to test include:
- Compatibility with your essential apps and workflows
- External display connectivity and performance
- Bluetooth and USB device recognition
- Wi-Fi and network performance
- Battery life on MacBook models
- Performance with resource-intensive applications
Looking Ahead
While macOS Tahoe 26.3 focuses on refinement rather than new features, Apple is already working on future updates. The company is expected to continue its regular update cycle throughout 2026, with potential new features arriving in later point releases or being saved for macOS 27, which is likely to be announced at WWDC 2026 in June.
Key areas where users hope to see improvements in future updates include:
- Enhanced Apple Intelligence capabilities
- Improved multi-monitor support
- Additional customization options for the Liquid Glass interface
- Performance optimizations for older Apple Silicon Macs
- Expanded functionality for the Phone and Games apps
