First macOS Tahoe 26.5 Beta Now Available for Developers

Apple released the first macOS Tahoe 26.5 beta for developers to test.

Developers can download the beta from System Settings > General > Software Update after enabling Beta Updates.

The update arrived six days after macOS Tahoe 26.4 and is developer-only for now, with a public beta expected in one to two weeks.

macOS Tahoe 26.5 could include Apple Intelligence Siri features, though some reports say features may be held for iOS 27.
