我们需要配置成 25 存储到磁盘上，并且清空内存，就是开机慢。
要速度快 请设置成 3
下面是官文的说明
hibernatemode = 0 (binary 0000) by default on supported desktops. The system will not back memory up to
persistent storage. The system must wake from the contents of memory; the system will lose context on
power loss. This is, historically, plain old sleep.hibernatemode = 3 (binary 0011) by default on supported portables. The system will store a copy of mem-ory memory
ory to persistent storage (the disk), and will power memory during sleep. The system will wake from
memory, unless a power loss forces it to restore from disk image.hibernatemode = 25 (binary 0001 1001) is only settable via pmset. The system will store a copy of mem-ory memory
ory to persistent storage (the disk), and will remove power to memory. The system will restore from
disk image. If you want "hibernation" - slower sleeps, slower wakes, and better battery life, you
should use this setting.
