pmset -g

I removed sleepimage, but after some time /private/var/vm/sleepimage appears again. Bug?

Did you disable it with sudo pmset -a hibernatemode 0 ?

If you don't then it will re-appear

Sorry, move this topic in https://forums.macrumors.com/forums/155/.

10.8.2 changed the way this worked, and removing the sleep image is not enough (for some stupid reason). After removing the sleep image, create a new file there, and make it unmodifiable:

sudo pmset -a hibernatemode 0
sudo rm /private/var/vm/sleepimage
sudo touch /private/var/vm/sleepimage
sudo chflags uchg /private/var/vm/sleepimage

Yes, this solved the problem. I'm doing this to optimize SSD.

Which model computer are you using? I get a sleepimage file on a new Mini but don't see it on Mac Pros.

Ah ok, I expect to see it on laptops but not on a Mini.

I noticed this problem with the reappearing sleepimage today and got somewhat frustrated. Glad I could go right here to these excellent forums and get a workaround. Thanks!

Hi

For me (Mac Mini Late 2012) none of the above solutions work. Only when I entered

sudo pmset -a hibernatefile /dev/null/sleepimage

(or what ever you like as name of the image), everything is working now as I expect and like it.

The steps in post #3 worked for me with my late 2012 Mini.

holy crap I made a thread about this two days ago and got flamed to **** over it. Good to see it is an actual issue and my question was valid, thanks for the responses everyone.

sudo pmset -a hibernatemode 0
sudo rm /private/var/vm/sleepimage
sudo touch /private/var/vm/sleepimage
sudo chflags uchg /private/var/vm/sleepimage

Thank you very very much!

Yeah, in 10.8.2 Apple changed how sleep image is dealt with. And I can't imagine writing 16GB to the SSD every time my laptop sleeps would do any good for the SSDs longevity.

yeh mine was writing 2.4GB and i was pretty annoyed about that. What a silly move by Apple.
