enb14 Posted November 30, 2005 Share Posted November 30, 2005 I found this so I would like to know if this is possible on OSx86 http://www.macosxhints.com/article.php?sto...58161&lsrc=osxh 1. Open Terminal, and type the following, pressing return after each line: sudo nvram nvramrc='" /" select-dev " msh" encode-string " has-safe-sleep" property unselect ' 2. Now type sudo nvram "use-nvramrc?"=true and press Return. You must now restart the Mac for the settings to take effect. 3. After the restart, go back to the Terminal, and enable hibernation: sudo pmset -a hibernatemode 3 If you use secure virtual memory, see the original instructions for different settings. This command should create a file named sleepimage in /var/vm. 4. Verify that everything worked -- put the Mac to sleep as you usually do, wait a few seconds, then wake it up. Use Console to view the System log, and make sure you see an entry that contains System SafeSleep. 5. Test Safe Sleep -- sleep the machine, wait a bit, then disconnect all power sources. Plug in the power sources again, and watch the new "wake from gray" sequence. Unfortunately for us nvram doesn't exist on intel so my question is if there's another way to enable this?

Lagerstatten Posted January 9, 2006 Share Posted January 9, 2006 It works on my 12" Powerbook, but I'm not sure if it'll work on Intel Macs. The only way to know is to try. I'll get my friend to try it out on his Toshiba laptop. Stay Tuned.

inignot Posted February 24, 2006 Share Posted February 24, 2006 http://matt.ucc.asn.au/apple/machibernate.html goes into detail about why this should work. Hibernate is mostly a software feature, and it can be enabled with an openfirmware command. The nvram call in the previous post sets this openfirmware command, but it seems intel macs can't use nvram. Is there another way to get into openfirmware and mess with stuff? If so, we can hopefully enable hibernation and have a working alternative to suspend.

munky Posted February 24, 2006 Share Posted February 24, 2006 intel macs dont have openfirmware. EFI is whats being used instead on intel macs, whereas our hacked boxes dont even have that. we are {censored} outta luck i think.

REVENGE Posted February 25, 2006 Share Posted February 25, 2006 FYI, some guy also created a control panel applet for Safe Sleeping in PPC OS X. Useful for future reference: http://david.djsiska.cz/index.php?postid=35 BTW, in case you didn't know before, all MacBook Pros have safe sleep mode enabled by default. It is activated in certain situations. Link to comment https://www.insanelymac.com/forum/topic/5134-safe-sleep-hybernate-on-x86/#findComment-62857 Share on other sites More sharing options...

enb14 Posted May 9, 2006 Author Share Posted May 9, 2006 Other link with info: http://www.andrewescobar.com/archive/2005/...sleep-your-mac/ I've tryied them on a hackintoch and doesn't works, if I change sudo pmset -a hibernatemode X with other times, for example 1 it now works like if I were suspended the computer, if I use 2 it works like a shut down. Has anyone got this working on a non mac hardware?
