macOS Tahoe 26.4 將登入 Keychain 綁定至裝置，無法手動複製到另一台 Mac
macOS Tahoe 26.4 將登入 Keychain 資料綁定至裝置專屬的 Secure Enclave 金鑰，使用者因此無法手動複製後在另一台 Mac 上使用。
情報判讀
訊號摘要
Apple 表示，這項 Keychain 變更可提升 macOS Tahoe 的安全性，因為登入 Keychain 不再能以手動方式轉移到其他 Mac。AppleInsider 也指出，針對 Mac 使用者的攻擊日益複雜，AI 可能促成更多惡意軟體與新入侵手法；不過，來源未說明是否存在替代的移轉方法。
為什麼值得注意
這項變更會直接影響需要在 Mac 之間移轉登入資料的使用者，也可能增加管理多台 Mac 的行政負擔。安全性提高的同時，Keychain 的裝置綁定意味著既有的手動複製流程將不再可用。
