Hi Every1, I 'm New To mac, i have MBP 13'' mid 2012 ,OSX 10.8.4 and i want to Hibernate this mac, in windows I know what hibernate do exactly but I heard that it does not not work the same way on mac, I know i can sleep my mac, but it juice the battery so fast, so How I hibernate my mac ,and does hibernating My mac is dangerous, or sleep mod is enough for mac and why.Thanks
 
Instead of "Hibernation", new Macs use something called "Safe Sleep". Your Mac does this by default.

When you close the lid on your MBP, the system writes the contents of RAM to the Hard Drive and sleeps, but it also keeps the system RAM alive like it would when you traditionally think about system sleep.

As long as the system has power (either battery or A/C), the system will quickly restore from sleep. But if the battery drains, the system will recover from the hibernated save state.

If you want to change how the system functions when put to sleep, check out this link: http://etherealmind.com/osx-hibernate-mode/

Basically, you have to go into the terminal and type a command. This is what DeepSleep does, just in a more friendly manner.

Power Nap is something completely different. It allows the system to periodically wake from sleep to connect to the internet so that things like Mail can be updated even while sleeping.
