Thanks for the Script and the launchd plist file. I think the reason while Apple has not implement the feature that only at the end on the battery source the suspend to RAM will be enabled is the battery replacement.

Thanks! This is great. I’ve produced a launchd plist which will run the script every 10 minutes. Put the (root executable) script in /usr/local/sbin/hibcontrol and the following in /Library/LaunchDaemons/localhost.hibcontrol.plist and do

sudo launchctl load /Library/LaunchDaemons/localhost.hibcontrol.plist

no need for cron file.

Stephen,

Here is an Apple article on scripting that may be of help:

John: That is weird, and offhand I have no explanation. Did you also delete the sleepimage file?

My macbook swutched from safesleep to ‘sleep’ always shutting down, and when powered on then restoring memory. I set hibernatemode=0 and now it sleeps and wakes fast, but still takes 30 seconds to go into sleep. Weird?

Derek (and others): Have you read my second TidBITS article on this topic? That article, rather than this blog post, was intended to be the last word on this subject, and it goes into more detail than I can here.

I wish I had the time to spell out every step of the process for getting this working in Terminal, but I’m afraid I don’t. Luckily, though, there are lots of resources out there on the Web already that do a fine job of explaining things like scheduling cron jobs, and I’m sure a few Google searches will provide the necessary info.

But I do want to emphasize that all of this is really only intended for computer geeks, not ordinary, nontechnical folk. This really is highly technical stuff, and I can’t recommend it for people who aren’t already familiar with Unix. That was really the point of my first article: not how to do this, but a lament that this is the only way it can be done, and thus available only to propellerheads!

I enjoyed the article, and have followed the TidBITS Talk discussion. I was glad to see your mention of summarizing and correcting the important points in your blog. So, here I am at the blog, and the only two comments posted so far each ask for more information on implementing your proposed script. There were two similar requests in the TidBITS Talk thread, and two or three answers given.

I recognize that you can’t provide a Terminal tutorial here, but I think it would make this blog entry vastly more useful to many more people, if you added a little more information. Adding the implementation instructions that have already appeared in TibBITS Talk would make your blog entry a complete resource for most readers interested in this subject.

Please consider revising your blog entry once more, to include information on implementing the script via the system chrontab, and perhaps via Greg’s approach, and other variations already detailed in TidBITS Talk. Make this blog entry a complete resource for understanding and responding to the issues that your TidBITS article raised.

Thanks,

Derek Rof

No problem. I’m going to bookmark Greg’s script and study up. At some point in the future I’ll come far enough that I’ll be able to get it up and running.

Stephen:

I mean no disrespect, but if your knowledge of the command line is that limited, you need more assistance than I have the time to provide. So sorry!

Joe:

That’s the article that actually brought me to your blog for what I hoped would be a more complete description of how to implement the script. Any help explaining how to set it up in terminal (even something as simple as making my way around the directory structure) would be greately appreciated.
