Instructions on how to hibernate with a swapfile
Macbook Pro C2D
Same problem with MacBook 2,1... I use Zenwalk so for me it's standby vs. hibernate. Standby works, hibernate does not.
My hibernate script actually runs standby if hibernate fails. As this was the case I never really saw the hibernate errors, I just assumed it was working. One thing that tipped me off was the first time I ran the hibernate script from the terminal vs. a gui option. It does sound like you've seen some error output, but I wonder if you could get more by opening a terminal and running whatever your hibernate binary is. For me it's:When I ran that I finally saw all of it's vomit and realized that it wasn't working as I thought. I haven't tried to fix it... I just settled for standby. I'm interested in seeing if there's a resolution, though!Code:sudo /usr/sbin/hibernate
