Hibernate between OS X and Bootcamp Win 7
- by Willem
Wouldn't it be great if someone wrote a guide or an app which allowed you to switch instantly between OS X and Windows using Hibernate in both OS:s?
Windows 7 already has an option "Hibernate" which allows you to boot back to your OS X partition, but OS X does not exactly offer the same.
However, there are possibilities here. It seems that the recent Mac's have 3 different kinds of sleeping mode:
Sleep: Low power consumption, RAM still active.
Legacy Safe Sleep: No power consumption(?), writes RAM to disk and shuts down (is this the same as Hibernate?)
Safe Sleep: Writes RAM to disk and enters sleep mode. If battery level drops too low it goes into Hibernate (is this Hibernate the same as #2 in this list? This is the Hibernate I will be referring to int he rest of this post)
It seems that I am unable to force my MacBook Pro (Late 2011) OS X 10.7.3 into a true hibernate using either command line or apps that are supposed to do this. I believe the Mac should show that white loading bar whilst waking up if it was truly put into hibernate (which it does not).
But I can get this white bar to show by letting my battery level drop to 0% so there is obviously a system function for it (obviously, duh! :).
When Win 7 goes into hibernate it shuts down completely and you can then boot into OS X on startup. On OS X however, hibernate forces you to wake up into OS X. Can you hack this so that you're allowed to select boot partition after OS X hibernates?
Would it be possible to use the true hibernate system functionalities of Win 7 and OS X to create a kind of instant switching between the two? Imagine this on a quick SATA-3 SSD like my 180GB Intel 520.
