Apple has rolled out the fourth Release Candidate for macOS Tahoe 26.7 and macOS Sequoia 15.8 to developers and public beta testers. The updates arrive shortly after the company's "Surprise and Shine" event, where it unveiled the iPhone Duo, iPhone 18 Pro, and iPhone 18 Pro Max.

Both macOS versions focus on bug fixes and performance improvements rather than new user-facing features. Apple has accelerated its security patch cycle thanks to advances in AI-assisted security research, making these updates particularly important for users.

The RC build for macOS Tahoe 26.7 is labeled 25G229, while macOS Sequoia 15.8 RC 4 carries build number 24H23. Final public releases are expected within the coming days.
