macOS 27 Golden Gate Kills Time Capsule Support

Apple's Time Capsule was introduced at Macworld Expo in January 2008, combining a Wi-Fi router with NAS-style network storage designed to work in tandem with the Time Machine backup software. Apple officially ended development on the entire Air Port line in April 2018, with the AirPort Express at $99, the AirPort Extreme at $199, and the AirPort Time Capsule at $299, available only while supplies lasted. The lineup sold out entirely by November 2018. Prior to that, Apple had not updated its AirPort products since 2013. AFP dates back to 1988, when Apple designed a native file-sharing protocol for the Macintosh as part of the AppleTalk networking suite. SMB became the primary file-sharing protocol in OS X 10.9 Mavericks in 2013, and the ability to run an AFP server was removed in macOS 11 Big Sur in 2020. Apple formally deprecated the AFP client in macOS Sequoia 15.5, and, when macOS 26 Tahoe launched, a warning in System Settings confirmed that AFP support and Time Capsule compatibility would end with macOS 27. As expected, the first developer beta of macOS 27 Golden Gate contains no AFP client at all, ending a protocol with more than 40 years of history in the Apple ecosystem. All Time Capsule models rely on AFP and SMBv1, the original Server Message Block version from 1987. From macOS 27 onwards, Time Machine requires SMBv2 or SMBv3, which covers modern NAS hardware but rules out every Time Capsule model in its stock form. macOS 27 also enforces stricter network security requirements, including TLS 1.2 as a minimum, which is a bar that Time Capsule hardware cannot meet. The community response is a GitHub project called TimeCapsuleSMB, created by James Chang, an engineer at Microsoft. Rather than replacing Apple's firmwar
