Although I may not encounter these situations myself, I grant that they make Safe Sleep more useful. However, several people pointed out usage scenarios in which someone might be delighted to have a copy of their RAM cached to disk, even if it meant taking a minute extra for their laptop to sleep. When Safe Sleep Is Good - In my earlier article, I complained that cases where Safe Sleep would actually be valuable are rare, at least for me, making it all the more irritating that saving RAM to disk is the default. If you don’t like waiting almost a minute before moving your computer every time you put it to sleep (and I certainly don’t), you must go to considerable effort to change that behavior. This default setting can be modified only by mucking around in Terminal or with The RAM is cached so that if, later on, your battery drains completely, you can return to your previous state quickly (a bit slower than waking up from ordinary sleep, but much faster than restarting), without having lost any unsaved work. Here, then, is the rest of the story (or as much of it as I know at the moment).Ī Quick Review - In Apple’s current implementation of Safe Sleep, simply putting your laptop into (ordinary) sleep mode triggers it to save a copy of your RAM onto disk – taking up as much as 4 GB of disk space and delaying the onset of sleep by as long as 49 seconds (depending on your laptop’s configuration), during which, Apple’s documentation cautions, you must not move your computer. Now it seems that even the follow-up needs a follow-up, as new information has emerged and various helpful hints have been offered.

It provoked lots of discussion on TidBITS Talk, not to mention numerous email messages, prompting me to write a follow-up post on my personal blog.

My recent article “ Stewing Over Safe Sleep” () seems to have touched a nerve.
