Mac update to resolve homebrew slow

Reference: Mac OS solve the problem HomeBrew update the X-slow

brew command under mac although very easy to use, but slow to update when met, one thing is very suck.

The easiest solution is to replace domestic sources.

Here we use USTC source (of course there are many other sources, self search), as follows:

1. Replace brew.git

cd "$(brew --repo)"
git remote set-url origin https://mirrors.ustc.edu.cn/brew.git

2. Alternatively homebrew-core.git and homebrew-cask.git

cd "$(brew --repo)/Library/Taps/homebrew/homebrew-core"
git remote set-url origin https://mirrors.ustc.edu.cn/homebrew-core.git

cd "$(brew --repo)/Library/Taps/homebrew/homebrew-cask"
git remote set-url origin https://mirrors.ustc.edu.cn/homebrew-cask.git

3. To perform the update

brew update
