[...] Today, 06:19 PM I don't think OSX hybernates like you are used to with windows… it kind of sleeps and hybernates at the same time. To get just hybernate you would want to look into something like this article talks about Hibernating your MacBook, a zero-software approach | Wheadon's Words; Mark's Mutterings [...]

There is a DeepSleep Widget that will hibernate your Mac or MacBook with one click. Check it out http://www.axoniclabs.com/DeepSleep/

Oli: that could be because you have “Use secure virtual memory” turned on in System Preferences->Security->General? If you have, try turning it off and see if that fixes things?

I can’t help with the problem of it waking itself up though — unless something’s squeezing the MacBook enough to press a key?

I find that when I have my MacBook set to enter deep sleep, it never comes out of it correctly. The machine always crashes.

On a related note, the MacBook’s started waking itself up for apparently no reason too

I was under the impression that when secure VM is set and you attempt to set the hibernatemode to an incorrect setting, that it will default to hibernatemode 0.
Actually secure VM is only an issue in a very small number of cases, since it was only in its first implementation that OSX handled SVM and smartsleep badly. To get around this, Apple added hibernatemodes 5 and 7, which are the same as 1 and 3 respectively, but for secure VM. They write an unencrypted VM image, even if you have SVM selected in preferences. If you refuse to update your OS, the script can easily be made to work by adding a few more if/else statements to include hibernatemode 5 and 7. This should not be an issue with updated OSX.v installs, where hibernatemodes 0-3 work just fine with SVM.

Easier still, just use smartsleep pref pane.

But do not use that on Macs with secure virtual memory [so presumably unticking "Use secure virtual memory" in System Preferences->Security->General will do the trick --mcw]

Well, there is an AppleScript application to manipulate the way your MacBook sleeps (and it also support “hibernate now” feature):

Alternately, one can just use the SmartSleep Pref Pane.

All good stuff. For the purposes of the article I wanted to avoid pmset and keep things entirely physical -- hence the visual way of figuring out if the machine is using sleep mode 3 rather than running pmset -g for example. People who use sudo pmset -a 1 to make the MacBook hibernate next time it sleeps (and use almost no power) need to remember to run sudo pmset -a 3 next time they switch on, or the MacBook will hibernate every time the lid's closed from then on. But in summary: the software that's missing from OS X as standard is this: something that tells the system to hibernate now, but doesn't change the default sleep behaviour -- something you click on when you know you've leaving the MacBook for a while and you would like it to consume no power in the mean time. The nearest to this that Mac OS X supports is Shut Down... which just isn't the same.
