One week after releasing the second macOS Sequoia 15.6 beta, Apple today sent the third beta of the upcoming macOS Sequoia 15.6 update to developers for testing.
Through the System Settings app's Software Update section, developers can choose to participate in the macOS Sequoia beta. To access the beta, you must have an Apple ID linked to an Apple Developer account.
The contents of macOS Sequoia 15.6 are yet unknown, as the first two betas revealed no new features. As Apple concentrates on macOS Tahoe, the newest version of macOS that will be released in the fall, its work on macOS Sequoia is drawing to an end.
