Apple rolls out Release Candidates for macOS Tahoe 26.7 and macOS Sequoia 15.8

Alongside macOS 27 developer beta 6, Apple also released the first RCs for macOS Tahoe 26.7 and macOS Sequoia 15.8. Here are the details.

Apple steps up macOS update schedule

Last week, Apple released macOS 26.6.2 beta 1, alongside the first round of betas for iOS 26.6.1 and its counterparts.

The reason for the mismatch is that Apple had released macOS 26.6.1 a few days earlier, alongside macOS Sonoma 14.8.9 and macOS Sequoia 15.7.9, which fixed a serious Screen Sharing bug.

Today, in addition to officially releasing macOS 26.6.2, Apple rolled out Release Candidates for macOS Tahoe 26.7 (25G220) and macOS Sequoia 15.8 (24H16).

The release notes mention only “This update provides important security fixes and is recommended for all users” for macOS Sequoia 15.8, and “This update provides security fixes for your Mac” for macOS Tahoe 26.7.

Although there are no specific details about what’s included in either update, they reinforce the notion that Apple has been accelerating its macOS release cycle to address vulnerabilities uncovered with the help of AI tools.

For macOS Tahoe users, the RC isn’t expected to introduce new features, as Apple’s focus has now turned to macOS 27 Golden Gate and its beta period ahead of the official release in a few weeks.

That said, we are looking into both systems and will report back if we find anything noteworthy.
