Tunnelblick on macOS Big Sur
> 关于Tunnelblick在新的macOS Big Sur中使用说明

If you are using macOS 11 Big Sur, you should use the latest version of Tunnelblick. You should enable Tunnelblick to automatically check for updates (on the "Preferences" panel of Tunnelblick's "VPN Details" window). You can also download the latest version from Tunnelblick Downloads.

> 首先确保你使用的是最新版本Tunnelblick.

The following is the current status of issues that have been seen using the latest version of Tunnelblick on macOS Big Sur.

> macOS Big Sur 系统中使用Tunnelblick会发生以下问题

To report an issue, please follow the instructions at Tunnelblick Issues.

CAN'T FIX: Tunnelblick's Tun and Tap system extensions do not load.

If your configuration requires a Tun or Tap system extension, connecting to your VPN will fail if an appropriate system extension is not loaded.

> 上面的几段话的意思就是，关于VPN的两种方式，TAP和TUN 会发生不能加载问题。

macOS Big Sur 11.0.1 does not allow Tunnelblick to load its Tun or Tap system extensions. Apple says that as a workaround "during development" one can temporarily disable System Integrity Protection to allow these system extensions to load when logged in as an Admin user. This workaround may not work in a future version or update of Big Sur — see The Future of Tun and Tap VPNs on macOS.

> macOS在未来Tap 和 Tun 的VPN模式在mac下被认为是破坏系统完整性的扩展，因此被禁用，目前只能通过**开发期间**模式，暂时禁用系统的完整性保护来确保加载vpn的扩展。

Note: If you are using a Tun VPN, you can modify your OpenVPN configuration file so it will work without the "Tun" system extension. See The Future of Tun and Tap VPNs on macOS.

FEATURE: Tunnelblick disables loading of Tun and Tap system extensions.

This is actually, really, truly a feature, not a bug!

> Tunnelblick 会在以后增加一个不再使用tun的特性。本人使用过程中，发现它的Tun模式还是可以继续使用之前的配置文件链接的，Tap模式则不行。**以下为解决办法：**

When running on macOS Big Sur, Tunnelblick forces the settings on Tunnelblick's "Advanced" settings window to "never load" system extensions. You can override that behavior and allow the settings to act normally, which is useful if you have disabled SIP and/or your version of Big Sur allows Tunnelblick to load the system extensions. You can override the behavior by executing the following command in Terminal:

> 强制覆盖Big Sur 的默认不加在系统扩展，改为正常加载,具体命令如下：

```shell
# 覆盖
defaults write net.tunnelblick.tunnelblick bigSurCanLoadKexts -bool yes
# 恢复
defaults delete net.tunnelblick.tunnelblick bigSurCanLoadKexts
```

> 官网文章的后半部分说明了一下无法修复的情况，无法修复的情况可能是使用了IPv6协议的VPN，在工作中目前还未使用到，因此此处不提。

觉得不错，点个赞？
