How can I put my MacBook Pro in hibernate mode?
If you want “hibernation” – slower sleeps, slower wakes, and better battery life, you should use this setting. To make a laptop or a desktop Mac always hibernate (suspend to disk), run: Setting hibernatemode to 25 decreases energy consumption during sleep but makes waking up take longer.

For example, to configure your Mac to wait for 60 minutes before it enters sleep mode below 40% battery and for 180 minutes above that threshold, you’d run the following commands: To have your Mac go into standby mode, you can either close the lid, press the power button, or select the “Sleep” option in the Apple menu.

How long does a MacBook Air last in sleep mode?
The MacBook Air has a 54-watt-hour battery, so a full battery should last about three days when in sleep mode (if the Mac does not enter standby mode) and about nine days if the Mac is turned off. The energy consumption in hibernation or standby mode is probably close to the energy consumption when the Mac is turned off.
What happens when you put a Mac to sleep?
This is the default sleep mode for all desktop Macs. Another sleep state found in Macs is safe sleep. It puts the contents of the RAM onto the hard disk each time you put it to sleep. In the event the battery begins to run low while sleeping or is left idle for long time, you won’t lose any work.
What does passing 0 do on MacBook Pro?
Passing 0 disables SafeSleep altogether, forcing the computer into a reg- ular sleep. 0000 0001 (bit 0) enables hibernation; causes OS X to write memory state to hibernation image at sleep time. On wake (without bit 1 set) OS X will resume from the hibernation image.
Why does my MacBook Pro go to sleep?
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 memory to persistent storage (the disk), and will power memory during sleep.
