    Is there a way that I can get a true hibernate behavior on a Mac?

    I don't want you to tell me that sleep is the same thing. It is amazing how every time a snobbish mac user will suggest this. Yes they are similar in what they accomplish, but there are differences in how they can be utilized.

    I want to be able to completely unload the OS so that when I turn the computer back on I can boot from a LiveCD but have my OSX windows retained for when I go back to booting OSX. This is exactly what Hibernate on windows allows you to accomplish.

    Is there a way to do this kind of 'save session' on the mac?

    IIRC, some Macs have a "deep sleep" option that I think is more like a true hibernate, but I haven't heard much about it in a while.

    This MacOSXHints article might have a little more info...

    No. It is not possible with the way the OS operates.

    I read that that is more of a macbook feature. Can I, how do I use this on an imac. Specifically I don't have a battery that will tell the OS that it is at only 4% charge or what not.

    Deep sleep is not what he is looking for, the moment you wake the computer it will go back to a previous state, not allow him to boot from another drive.

    AFAIK, there is no equivalent to it.

    So, do you recommend just saving what I can and making all the other necessary preparations, or is there something that can be done? I am switching OS's a lot and many times I'll need to boot into it so even though I use virtual machines, that isn't the solution to everything. I don't want it to be a production every time I need to switch.

    If you are switching OSes, why not use Parallels or Fusion? I believe Fusion will even support multiple versions of OSX running at the same time and they will both support any Intel/x86 OS.

    Use SmartSleep to enable hibernation

    Sure, it is possible. See http://www.jinx.de/SmartSleep.html to enable hibernation, or a combination of sleep/hibernate.

    But not for what he is trying to do, which is have the computer basically reboot and be interrupted to start from another drive before waking up from hibernate.

    As stated, I need things that the virtual machine cannot offer, like direct access to the wireless card, not through NAT. Optionally, I could boot into linux and virtualize OSX as I don't really need anything from OSX, but I have never made a virtual machine running OSX, is it tricky?
