macOS 14 (Sonoma) 存在[一个小问题](https://github.com/hwdsl2/setup-ipsec-vpn/issues/1486)，可能会导致 IKEv2 VPN 每 24-48 分钟断开并重新连接一次。其他 macOS 版本不受影响。首先[检查你的 macOS 版本](https://support.apple.com/zh-cn/HT201260)。要解决此问题，请按以下步骤操作。
-**注：** 应用此解决方案后，更新后的 VPN 服务器配置可能不适用于 Windows 或 Android 客户端。对于这些客户端，你可能需要在 `ikev2.conf` 中将 `pfs=yes` 更改回 `pfs=no`，然后运行 `service ipsec restart` 或重启 Docker 容器。
+**注：** 如果你在 2023 年 12 月 10 日之后安装了 IPsec VPN，则无需执行任何操作，因为已经包含以下修复。
-1. 编辑 VPN 服务器上的 `/etc/ipsec.d/ikev2.conf`。首先将 `pfs=no` 替换为 `pfs=yes`。然后找到这些行 `ike=...` 和 `phase2alg=...`，并将它们替换为以下内容，开头必须空两格：
