Mac盒盖掉电严重

Mac book pro 盒盖后第二天掉电 40%,而且发烫,原因是有进程阻止休眠。

通过 pmset -g 可以看到阻止的程序是 sharingd

$ pmset -g

通过 pmset -g assertions 发现 sharingd 背后的程序是 接力。也就是你打开 iPhone QQ、微信等程序的时候,可能会提示剪切板来自 macboook-xxx,相当于一个云剪切板,这个功能比较鸡肋,可以去掉。

$ pmset -g assertions

【偏好设置】 -> 【通用】 ,取消 允许在这台Mac和icloud设备之间使用接力-w668

接着运行 pmmset -g 已经找不到组织睡眠的程序了。

$ pmset -g

另外建议盒盖前,把蓝牙、WiFi 都关掉。
