一、安装Homebrew
注：Homebrew 类似linux下的yum、apt等包管理软，这里要利用这个包管理软件安装sleepwatcher
1. 创建Homebrew要使用的目录
sudo mkdir /usr/local/Homebrew
sudo mkdir /usr/local/Cellar
2. 同步brew.git库
sudo git clone https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/brew.git /usr/local/Homebrew
3. 添加替身（软链接）
sudo ln -s /usr/local/Homebrew/bin/brew /usr/local/bin/brew
4. 同步core库
sudo mkdir -p /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core
sudo git clone https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/homebrew-core.git /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core
5. 同步cask
sudo mkdir -p /usr/local/Homebrew/Library/Taps/homebrew/homebrew-cask
sudo git clone https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/homebrew-cask.git /usr/local/Homebrew/Library/Taps/homebrew/homebrew-cask
6. 提权
sudo mkdir -p /usr/local/var/homebrew/locks
sudo chown -R $(whoami) /usr/local/Homebrew
sudo chown -R $(whoami) /usr/local/Cellar
sudo chown -R $(whoami) /usr/local/var/homebrew
7. 查看版本号
brew -v
8.更换镜像源(提高下载速度）
cd "$(brew --repo)"
git remote set-url origin git://mirrors.ustc.edu.cn/brew.git
zsh用户：
echo 'export HOMEBREW_BOTTLE_DOMAIN=https://mirrors.ustc.edu.cn/homebrew-bottles' >> ~/.zshrc
source ~/.zshrc #刷新
bash用户：
echo 'export HOMEBREW_BOTTLE_DOMAIN=https://mirrors.ustc.edu.cn/homebrew-bottles' >> ~/.bash_profile
source ~/.bash_profile #刷新
9. 更新源
brew update
10. 建立一些需要的目录并授权
chmod u+w /usr/local/bin /usr/local/share
sudo chmod 777 /usr/local/bin
sudo chmod 777/usr/local/share
sudo mkdir -p /usr/local/Frameworks /usr/local/etc /usr/local/include /usr/local/lib /usr/local/opt /usr/local/sbin
sudo chown -R $(whoami) /usr/local/Frameworks /usr/local/etc /usr/local/include /usr/local/lib /usr/local/opt /usr/local/sbin
homebrew安装完成
二、安装sleepwatcher
brew install sleepwatcher
brew services start sleepwatcher
ps aux | grep sleepwatcher #检查sleepwatcher进程是否已运行
三、配置sleepwatcher
touch ~/.wakeup #唤醒时要执行的命令脚本
touch ~/.sleep #睡眠时要执行的命令脚本
chmod u+x ~/.wakeup
chmod u+x ~/.sleep
四、验证sleepwatcher是否工作
1. 在~/.wakeup文件中写一条命令
vi ~/.wakeup
======================
echo "a" >> ~/sleep.log
======================
2. 使电脑睡眠后再唤醒
3. 查看~/sleep.log文件内容
cat ~/sleep.log #正常的话每睡眠唤醒后会多一行“a”
五、自动调整分辩率
在~/.wakeup中添加一行命令
=========================
source /usr/local/bin/disflick.sh
=========================
希望在唤醒后自动执行之前编本的用于解决闪屏问题的/usr/local/bin/disflick.sh脚本，该脚本的详情见：http://blog.chinaunix.net/uid-8204701-id-5837989.html
未能成功，待解决。有知道的朋友请留言告知，谢谢！
注：使用https://github.com/osy86/HaC-Mini/issues/7介绍的方法，经验证可以实现自动更改分辩率以解决闪屏问题。但此方法较为死板，如：分辩率为1080P的情况下，唤醒后会被自动改为2K。
