Apple has released macOS Tahoe 26.6 Release Candidate to developers, marking the final stage of testing before the update reaches all users. The release arrives after several weeks of beta testing focused on bug fixes, security improvements, and system stability rather than new features.
macOS Tahoe 26.6 RC carries build number 25G70 and is expected to become the final public release unless Apple discovers any last-minute issues. With macOS Golden Gate arriving this fall, Apple is now wrapping up the Tahoe update cycle before shifting development attention to the next major version of macOS.
Unlike major macOS releases, macOS Tahoe 26.6 does not introduce any major user-facing features. The update focuses on improving reliability, fixing bugs discovered during testing, and delivering the final round of refinements before the software is released publicly.
macOS Tahoe 26.6 beta timeline
Apple tested macOS Tahoe 26.6 for several weeks before reaching the Release Candidate stage. The update followed a steady beta schedule alongside iOS 26.6, iPadOS 26.6, watchOS 26.6, and tvOS 26.6 releases.
- Beta 1: May 26, 2026
- Beta 2: June 15, 2026
- Beta 3: June 29, 2026
- Beta 4: July 6, 2026
- Beta 5: July 13, 2026
- Release Candidate: July 20, 2026
During the beta cycle, Apple focused on polishing macOS Tahoe rather than adding new functionality. This is expected for a late-cycle maintenance update, especially with macOS Golden Gate already being tested ahead of its September release.
Final update before macOS Golden Gate
macOS Tahoe 26.6 represents one of the final major updates for the current macOS generation. The upcoming macOS Golden Gate release brings the next wave of changes, including deeper Apple Intelligence integration, Visual Intelligence features, and the transition away from Intel Mac support.
For users who are not running beta software, macOS Tahoe 26.6 will mainly deliver a more stable experience rather than noticeable new features. The update is still important as it provides Apple with one final opportunity to address issues before moving fully toward macOS Golden Gate.
If you are enrolled in Apple’s beta program, macOS Tahoe 26.6 Release Candidate is available through System Settings > General > Software Update. While Release Candidate builds are usually identical or very close to the final public version, they remain pre-release software.
Apple is expected to release macOS Tahoe 26.6 to all users soon, making it one of the final updates before macOS Golden Gate launches alongside iOS 27 and iPadOS 27 this fall.
