这就是你如何做到的。这适用于第1代，第2代和第3代的rpi。
我将bash函数中的代码分开，以使其更具可读性。
可能存在无关mount/ unmounts，但是大多数diskutil操作导致MacOS自动挂载卷，因此我们需要在继续之前卸载它们，否则命令会导致资源忙。
我们需要安装一些依赖项。这部分并不像我希望的那样自动化。

现在编辑该文件并在以下caveat部分后添加到该文件：
patch do
url "https://github.com/alperakcan/fuse-ext2/files/2576060/0001-Fix-new-Xcode-compilation.patch.txt"
sha256 "a2a8ff14f36754aead1745b4b5f53b0333376d1bf6abe659ec4eacdbb232aceb"
end
现在我们安装依赖项：
brew install \
findutils \
e2fsprogs \
pv
brew install --head ./fuse-ext2.rb
sudo cp -pR /usr/local/opt/fuse-ext2/System/Library/Filesystems/fuse-ext2.fs /Library/Filesystems/
sudo chown -R root:wheel /Library/Filesystems/fuse-ext2.fs
sudo cp -pR /usr/local/opt/fuse-ext2/System/Library/PreferencePanes/fuse-ext2.prefPane /Library/PreferencePanes/
sudo chown -R root:wheel /Library/PreferencePanes/fuse-ext2.prefPane
最后，这是格式化SD卡的脚本。复制粘贴此脚本，使其可执行chmod a+x FILE，并用两个参数调用它DEVICE和MODEL。
该脚本非常智能，可以为您提供DEVICE和MODEL的正确值。
