购买了全新的 Macbook Air，然后成功安装了 Ubuntu 14.04 64 位，但主要硬件不兼容，例如 WiFi 卡和鼠标垫无法像在 OSX 中那样顺畅运行。如何修复 WiFi，因为我的 MacBook Air 上没有其他网络接口。
选项：这是我的安装方法：
步骤1：在 Mac OSX 10.9.2 上打开磁盘实用程序，我调整了 80GB 的 Mac 空间和 40GB 的未分配空间
第2步：可选：refind-bin-0.8.0.zip，基本上它是一个 GUI 可启动屏幕，如果我不安装它，也没有什么大不了的，因为 Ubuntu 有自己的 TUI GRUB 菜单。很困惑所以无论如何都安装了它。

步骤3：下载用于可启动 USB 的 Ubuntu 14.04 64 位 ISO
$ hdiutil convert -format UDRW -o ubuntu-14.04-desktop-amd64.img ubuntu-14.04-desktop-amd64.iso

注意：有线弹出窗口出来了，按“忽略”
$ diskutil eject /dev/disk1
Disk /dev/disk1 ejected
步骤4：重新启动并用 USB 启动，执行我选择“其他”的分区来创建 Ubuntu 分区，并通过选择 EFI 完成 Ubuntu 设置
启动 Ubuntu 后无法使用 WiFi，也没有其他方式可以上网，所以切换回了 Mac OSX
