我有几台配备双 SSD 的 iMac，它们都安装了 Ubuntu 16.04 LTS 和 MacOSX。众所周知，问题是 MacOSX 安全补丁中有一个错误，禁用了 BCM57765 卡。我已按照 MacOS X 上的所有建议步骤操作，但该卡仍未启用。更糟糕的是，我无法再在 Ubuntu 上启用该卡。由于 Ubuntu 是我在这些机器上的主要操作系统，我只关心以太网卡是否能与 Ubuntu 配合使用。我现在只能在这台机器上使用 wifi。
根据我的研究，我确信很多 Ubuntu 用户在 iMac 硬件方面也遇到了同样的问题。
我在这里有一些帖子https://discussions.apple.com/message/31196301?ac_cid=op123456#31196301
希望你们中的一些人能给出一些关于如何再次启用此卡的提示。它之前是可以工作的。我检查了电缆、开关等。它在另一台机器上工作得很好。是糟糕的 MacOS X 更新禁用了此卡。我还运行了诊断程序，该卡绝对没有问题。
先感谢您！
以下是该机器的一些输出：
