安装完黑苹果后用的免驱网卡BCM94360CS2 自动睡眠后，后出现蓝牙不能用的情况。必须把蓝牙开关一下才行。经过网上的搜索目前问题已经解决
准备工作
下载sleepwatcher
推荐官网直接下载，地址: https://www.bernhard-baehr.de/。(地址可能需要翻墙才能访问)
安装blueutil
blueutil是一个蓝牙工具，可以通过命令打开和关闭蓝牙，推荐使用homebrew下载
brewinstall blueutil
安装sleepwatcher
首先通过终端进入sleepwatcher的文件夹，以我的为例，版本为sleepwatcher_2.2.1
cd sleepwatcher_2.2.1sudo cp./sleepwatcher /usr/local/sbinsudo cp./sleepwatcher.8 /usr/local/share/man/man8#创建数据文件夹，这个可以自定义，如果选择不同的路径，下面的路径也必须跟着修改mkdir~/.sleep
紧接着创建2个脚本，一个用于启动蓝牙，一个用于关闭，分别把这两个文件放到~/.sleep/
下面是rc.sleep文件，用于睡眠时关闭蓝牙
#!/bin/bash# rc.sleep# Stop Bluetooth Module on Mac OS X## Requires Blueutil to be installed: http://brewformulas.org/blueutilBT="/usr/local/bin/blueutil"log(){# logger -p notice -t bt_restarter "$@"echo"$@">>~/.sleep/sleepwatcher.log}err(){echo"$@">&2echo"$@">>~/.sleep/sleepwatcher.log# logger -p error -t bt_restarter "$@"}log""log"sleep at $(date+"%Y-%m-%dT%H:%M:%S")"if[-f"$BT"];then
if[[$("$BT"-p)==0]];then
log"Bluetooth is off, nothing to do."else
log"Bluetooth on, stopping ..."($("$BT"-p0)&> /dev/null&&echo"Bluetooth Module stopped")||(err"Couldn't stop Bluetooth Module"&&exit 1)log"Successfully stoped Bluetooth"&&exit 0fi
else
err"Couldn't find blueutil, please install http://brewformulas.org/blueutil"&&exit 1fi
下面是rc.wakeup，用户唤醒时打开蓝牙
#!/bin/bash# rc.wakeup# Restart Bluetooth Module on Mac OS X## Requires Blueutil to be installed: http://brewformulas.org/blueutilBT="/usr/local/bin/blueutil"log(){# logger -p notice -t bt_restarter "$@"echo"$@">>~/.sleep/sleepwatcher.log}err(){echo"$@">&2echo"$@">>~/.sleep/sleepwatcher.log# logger -p error -t bt_restarter "$@"}log"wakeup at $(date+"%Y-%m-%dT%H:%M:%S")"if[-f"$BT"];then
if[[$("$BT"-p)==0]];then
log"Bluetooth is off, Starting Bluetooth..."($("$BT"-p1)&> /dev/null&&echo"Bluetooth Module started")||(err"Couldn't start Bluetooth Module"&&exit 1)else
log"Bluetooth on, restarting ..."($("$BT"-p0)&> /dev/null&&echo"Bluetooth Module stopped")||(err"Couldn't stop Bluetooth Module"&&exit 1)($("$BT"-p1)&> /dev/null&&echo"Bluetooth Module started")||(err"Couldn't start Bluetooth Module"&&exit 1)log"Successfully restarted Bluetooth"&&exit 0fi
else
err"Couldn't find blueutil, please install http://brewformulas.org/blueutil"&&exit 1fi
下一步是给这两个文件添加上可执行权限
cd~/.sleepchmod u+x rc.sleep rc.wakeup
成功后，创建文件 ~/Library/LaunchAgents/de.bernhard-baehr.sleepwatcher.plist，粘贴下面内容
<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"><plistversion="1.0"><dict><key>Label</key><string>de.bernhard-baehr.sleepwatcher</string><key>ProgramArguments</key><array><string>/usr/local/sbin/sleepwatcher</string><string>-V</string><string>-s ~/.sleep/rc.sleep</string><string>-w ~/.sleep/rc.wakeup</string></array><key>RunAtLoad</key><true/><key>KeepAlive</key><true/></dict></plist>
最后一步，执行命令
这里是进入~/Library/LaunchAgents 目录下执行下面的命令
launchctl load de.bernhard-baehr.sleepwatcher.plist
执行完后，可能会弹窗请求授权，这时正常通过即可，这时你可以直接直接选择睡眠和唤醒，查看效果。
你可以通过执行命令cat ~/.sleep/sleepwatcher.log查看睡眠和唤醒时启动和关闭蓝牙的日志。
