说明
最近使用Mac电脑，发现Git不知道怎么升级，查了一下，特此记录
步骤
首先，在terminal执行
which git
/usr/bin/git会显示
/usr/bin/git再执行
git --version会显示
git version 2.37.1 (Apple Git-137.1)这个时候用的Xcode上的Git，再执行
brew install gitHOMEBREW_BREW_GIT_REMOTE set: using https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/brew.git as the Homebrew/brew Git remote.

To relink, run:
brew unlink git && brew link git关闭terminal，重新查看git版本，执行
git --version会显示如下：
git version 2.39.2此时已经是当前最新版本了，再核查路径：
which git显示如下：
/opt/homebrew/bin/git显示路径与原来的Git安装路径一致。至此，Git版本升级完毕。
