问题[mac-mini](ubuntu)

我在 Mac Mini 8,1 上运行 Ubuntu。“未找到 WiFi 适配器”我从 20.04 开始，只升级以获得最新的 Linux 固件，希望能让 wifi 正常工作。我还将内核版本更新为 5.7.1，因为希望能够为这个 BCM4364 排序固件。

$ lspci -vvnn | grep -A 9 Network

    Capabilities: <access denied>
    Kernel modules: brcmfmac

然后我检查它是否正在加载，我可以看到固件在启动后尝试加载，这可能是问题所在。

我认为它已经完成了这项工作，但可能需要启动？我尝试了 modprobe，但它并没有改变我能看到的任何东西。请不要建议任何旧的 Broadcom b43 驱动程序/修复程序，因为它们都与该芯片无关。

我有一个全新的 2020 Mac mini（Intel i3 四核芯片）。我的安装（专用 Ubuntu NO 双启动）因著名而失败；

执行“grub-install /dev/nvme0n1”失败。这是一个致命错误。

我通过启动进入恢复模式并选择“无安全性”和“允许从外部驱动器启动”绕过了 T2 芯片。因此，当我打开 Mac mini 并按下 Alt 键时，它会显示两个图标来选择启动、硬盘驱动器和闪存驱动器。我的闪存驱动器有ubuntu-20.04-desktop-amd64.iso，它已由我工作的 Ubuntu 14.04 LTS 笔记本电脑上的启动磁盘创建者制作成可启动的 USB。

无论我做什么，安装都会失败，Mac mini 随后会启动到功能有限的旧 Grub 2.04。

我无法遵循这个好建议在 mac mini 2018 上安装 ubuntu 18.04，因为我无法以这种方式安装 rEFInd。

我已经尝试了几个 Matt Gadient（传奇）可启动 iso 版本。

我已经使用 gparted 将整个驱动器重新格式化为 gpt 并且基本上从头开始但找不到任何可以让安装程序完成的分区组合（除了在没有 EFI 分区时强制它安装，在这种情况下安装程序不会失败但显然Mac mini 无法启动任何东西）。

我已经从这些页面尝试了几个手动 grub-install 选项，但最常见的错误是 /cow is busy and it cannot be unmounted。

当我使用 boot-repair 启动时，程序运行但它没有检测到任何东西。如果我终端和 lsblk 从该程序中它甚至不显示 nvme0n1 驱动器。

那么，有什么想法可以让安装程序工作或如何手动安装 grub？

我是一名 Ubuntu 新手用户，按照本教程在运行 Ubuntu 18.04 的 Mac Mini 4.1 上使用mbpfan启用风扇管理。

我最初取得了很好的成功，然后尝试将mbpfan变成系统服务。我遇到的第一个问题是安装后我的系统上没有 mbpfan.service 文件，所以我只是从 GitHub下载它，通过 SFTP 将它上传到我的下载文件夹，然后按照指示复制它sudo cp mbpfan.service /etc/systemd/system/。

但这是我尝试执行时的结果sudo systemctl enable mbpfan.service：

Synchronizing state of mbpfan.service with SysV service script with /lib/systemd/systemd-sysv-install.
Executing: /lib/systemd/systemd-sysv-install enable mbpfan
Failed to enable unit: File mbpfan.service: Invalid argument

我有点卡在这一点上，希望能轻推一下。谢谢你。

我的 Mac mini 在没有连接显示器的情况下无法启动。正如我在互联网上的各种论坛上所读到的，如果打开了 SSH，Mac OS X 允许 Mac Mini 在没有连接显示器的情况下启动。显然，EFI 中有一个设置。

是否也可以在 Linux 中应用此设置？
