众所周知, MacBook Pro是不用关机的 🐶
然而最近一段时间, 早上合盖, 中间并没有打开过, 晚上再看的时候, 电量基本都会下降 10-30% 不等, 经过查询搜索, 总结如下
查询阻碍进入深度睡眠(唤醒)的原因
pmset -g 查看 sleep 那一行, 会有 sleep prevented by 的字样, 我看到的是sharingd, 根据字面意思, 应该是分享服务, 但是经过检查, 所有分享功能都已经关闭. 我回忆了一下, 也有尝试过合盖前把平时比较耗电的Chrome、IDE、虚拟机啥的都关掉, 还是会掉电
推断可能不是这些前台程序导致的唤醒, 节能选项里也是没有开启小憩的
最后, 找到了 https://github.com/xinstein/PleaseSleep, 并在今天进行了简单测试, 晚上回家后一看, 卧槽, 电量100%, 惊了!!!
脚本的一点问题
时间有点久了, 脚本里提到的 Sleepwatcher 已经从 2.2 更新到了 2.2.1 因此需要小小修改一下, 把代码贴到这里做个备份
