概括
我的 MacBook Pro 一直没有进入休眠状态，例如，在包里放了几个小时后，它仍然很热。以下是上次发生这种情况时 pmset 日志中的一些信息。关键行如下：
在这里盖上盖子：
2019-05-22 21:47:04 -0700 Sleep Entering Sleep state due to 'Clamshell Sleep':TCPKeepAlive=active Using Batt (Charge:70%) 9808 secs
...然后我打开它后，它报告了这个：
2019-05-23 07:59:52 -0700 DarkWake DarkWake from Standby [CDN] due to EC.DarkPME ARPT/HID Activity: Using BATT (Charge:55%) 2 secs
我尝试了以下方法：
- 检查活动监视器中是否存在任何妨碍睡眠的事情，没有。
日志活动看起来有点奇怪，它报告电池电量为 70%，然后才变为 55%，所以也许还有其他问题。

答案1
检查“设置/节能器”，确保电池供电时未启用 Power Nap。我甚至在插入电源时也禁用了它。
另请查看与“地址簿同步”相关的此答案：https://apple.stackexchange.com/a/237552/334268
长话短说
看来您的 Mac 在 00:30 从轻度睡眠状态唤醒了一次，持续了将近一分钟，然后在 07:59 打开盖子时从待机状态唤醒。
此外，如果您在此之前没有打开它，它似乎会在 09:00 再次被唤醒：
2019-05-23 00:30:31 -0700 Notification Next immediate inactivity window start:'2019-05-23 00:30:00 -0700' end:'2019-05-23 09:00:00 -0700'
默认情况下，mac 会配置为处于轻度睡眠状态 3 或 4 小时。在此期间，它们可以执行同步等后台任务。
日志中有趣的部分从 开始Assertion status system-wide:。
如果我的解释正确的话，似乎您进行了云照片同步，耗时不到一分钟：00:00:48 BackgroundTask named: "com.apple.cloudphotosd.darkwake.sync"，对应于此条目：
2019-05-23 00:30:31 -0700 Assertions PID 2111(cloudphotosd) Released BackgroundTask "com.apple.cloudphotosd.darkwake.sync" 02:43:56 id:0x0xb00008301 [System: PrevIdle DeclUser IntPrevDisp kDisp]
还有一个地址簿同步：00:00:32 BackgroundTask named: "com.apple.AddressBook.ScheduledSync。
最后一个被标记为PreventUserIdleSystemSleep，所以它可能是罪魁祸首。或者两个同步都占了 15%。
在 55% 之前报告 70% 可能是系统实际轮询电池当前值之前的故障。我看到这种情况甚至在打开盖子时在用户界面中发生。登录前电池会显示最后记录的值，登录后会显示真实值。
