Reinstall My Mac - Problems and steps
把光标移动的速度调到最快：
System Preferences => Keyboard => Key Repeat Rate 调到 Fast
System Preferences => Keyboard => Delay Until Repeat 调到 Short
让Touchpad支持三个指头触摸可以Drag窗口：
System Preferences => Accessiblity => Mouse & Touchpad => Touchpad option => Enable Dragging => Three finger drag
设置中英文切换的快捷键：
System Preferences => Keyboard => Shortcut => Input Source => （把两个都check起来，描述自己看）
把希捷的移动硬盘驱动装好（NTFS_for_MAC），不然时光机不能写入备份，
尽管时光机所使用的分区不是NTFS，但是我发现不装这个驱动，仍然不能写入。
最好是先把命令行代理配置好，不然有些东西下不到或者很慢：
命令行：touch ~/.bash_profile
打开新创建的文件，加入以下几行（根据自己的代理端口配置好）：
export HTTP_PROXY="http://127.0.0.1:1087"
export HTTPS_PROXY="http://127.0.0.1:1087"
export ALL_PROXY="socks5://127.0.0.1:1086"
命令行: source ~/.bash_profile
如果是zsh的话，就是 source ~/.zshrc
使立即配置生效
不过我装nvm的时候，还是需要把.bash_profile 里面nvm自己写入的那段加载脚本，粘贴到.zshrc里面
nvm默认只会加到.bash_profile里面
让Git走sock5 代理（似乎在命令配置过代理之后，git仍然不能走那个代理，所以单独再给它配置）：
git config --global http.proxy 'socks5://127.0.0.1:1086'
git config --global https.proxy 'socks5://127.0.0.1:1086'
想要取消的话可以：
git config --global --unset http.proxy
git config --global --unset https.proxy
命令行： xcode-select --install
安装完之后 curl 执行出现 fail 443 的问题可以解决， 就可以安装 Homebrew 了（ https://brew.sh/ ）
命令行： /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

——————————————————————————————————————————————
装完 Homebrew 之后，最好运行以下 brew doctor，看看有提示什么问题
再来装一个 Oh My ZSH（ https://ohmyz.sh/ ），让命令行更适合开发者：
装完之后： Please look over the ~/.zshrc file to select plugins, themes, and options.
如果要想在 zsh 和 bash 之间切换，方法如下：
命令行：chsh -s /bin/bash
命令行：chsh -s /bin/zsh
还可以在 System Preferences > Users & Groups 用户名上右键 Advanced options 里面修改
还可以查看以下自己的mac支持哪些shell
命令行：cat /etc/shells
- 安装pyenv的时候发现它有这些的依赖：
- brew install pyenv
==> Installing dependencies for pyenv: autoconf, openssl@1.1, pkg-config and readline
用 Homebrew 安装的，被放在这个位置 /usr/local/Cellar/pyenv/1.2.16
安装完成之后，有很多陷阱提示，需要根据情况配置：
————————————————————————————————————————————————————————
==> Caveats
==> autoconf
Emacs Lisp files have been installed to:
/usr/local/share/emacs/site-lisp/autoconf
==> openssl@1.1
A CA file has been bootstrapped using certificates from the system
keychain. To add additional certificates, place .pem files in
/usr/local/etc/openssl@1.1/certs
and run
/usr/local/opt/openssl@1.1/bin/c_rehash
openssl@1.1 is keg-only, which means it was not symlinked into /usr/local,
because openssl/libressl is provided by macOS so don't link an incompatible version.
If you need to have openssl@1.1 first in your PATH run:
echo 'export PATH="/usr/local/opt/openssl@1.1/bin:$PATH"' >> ~/.zshrc
For compilers to find openssl@1.1 you may need to set:
export LDFLAGS="-L/usr/local/opt/openssl@1.1/lib"
export CPPFLAGS="-I/usr/local/opt/openssl@1.1/include"
For pkg-config to find openssl@1.1 you may need to set:
export PKG_CONFIG_PATH="/usr/local/opt/openssl@1.1/lib/pkgconfig"
==> readline
readline is keg-only, which means it was not symlinked into /usr/local,
because macOS provides the BSD libedit library, which shadows libreadline.
In order to prevent conflicts when programs look for libreadline we are
defaulting this GNU Readline installation to keg-only.
For compilers to find readline you may need to set:
export LDFLAGS="-L/usr/local/opt/readline/lib"
export CPPFLAGS="-I/usr/local/opt/readline/include"
For pkg-config to find readline you may need to set:
export PKG_CONFIG_PATH="/usr/local/opt/readline/lib/pkgconfig"
————————————————————————————————————————————————————
按照pyenv 的github说明： https://github.com/pyenv/pyenv#homebrew-on-macos
继续完成配置。
除了前面brew给默认安装的依赖之外，pyenv还有一些依赖：
brew install sqlite3 xz zlib
——————————————————————————————————————————————————————
==> Caveats
==> sqlite
sqlite is keg-only, which means it was not symlinked into /usr/local,
because macOS provides an older sqlite3.
If you need to have sqlite first in your PATH run:
echo 'export PATH="/usr/local/opt/sqlite/bin:$PATH"' >> ~/.zshrc
For compilers to find sqlite you may need to set:
export LDFLAGS="-L/usr/local/opt/sqlite/lib"
export CPPFLAGS="-I/usr/local/opt/sqlite/include"
For pkg-config to find sqlite you may need to set:
export PKG_CONFIG_PATH="/usr/local/opt/sqlite/lib/pkgconfig"
==> zlib
zlib is keg-only, which means it was not symlinked into /usr/local,
because macOS already provides this software and installing another version in
parallel can cause all kinds of trouble.
For compilers to find zlib you may need to set:
export LDFLAGS="-L/usr/local/opt/zlib/lib"
export CPPFLAGS="-I/usr/local/opt/zlib/include"
For pkg-config to find zlib you may need to set:
export PKG_CONFIG_PATH="/usr/local/opt/zlib/lib/pkgconfig"
