1.待机
计算机在待机状态时,内存中的信息未存入硬盘中,计算机可以被迅速唤醒。如果断电,内存数据将丢失无法常唤醒。
2.休眠
计算机在关闭前首先将内存中的信息存入硬盘,唤醒时将硬盘上的数据重写回内存。休眠状态下的唤醒速度比待机慢,好处是休眠后可以断电。
在Mac中就只有睡眠一种待机模式了。默认情况下Mac的睡眠相当于windows的待机模式。虽然Mac mini的待机功耗非常低,不过长期待机浪费的电加起来也不少,对产品寿命也会有些影响。实际上Mac已经提供了对休眠功能的支持,稍微做些设置即可将睡眠的默认行为由待机改为休眠。
Mac的睡眠方式说明:
0.(quick): Default sleep behavior on most Apple computers. RAM is still powered on while
sleeping. Wake up is fast. Safe sleep is disabled.
1.(deep): Hibernation behavior. System is totally shut down while sleeping. RAM contents
are dumped to disk. Wake up is slow.
3.(safe): Default behavior on Powerbook HD and later computers. RAM is still powered
on while sleeping. Wake up is fast. Safe sleep is enabled, so RAM contents are

5.(deep): Same as mode 1 for systems with encrypted virtual memory.
7.(safe): Same as mode 3 for systems with encrypted virtual memory
注: 我使用5的时候无法正常唤醒,因此不建议使用5&7
查看当前的睡眠模式: pmset -g | grep hibernatemode

现在你知道关机、待机和睡眠之间的区别了吧,为了更好的保护我们的电脑,和减少不必要的电量耗损,我们在不使用电脑时,应该尽量将它关机或者设置成睡眠模式。
