timdoug's interesting tidbits

Little bits of technical documentation and such. Hopefully helpful.

My 2007-era MacBookPro3,1 doesn't fully go to sleep / cannot wake from sleep with 10.8!

Yep, I had a reason to break out my old MBP and install the newest version of OS X on it. It works wonderfully for a five year old box (the SSD sure helps!), except for not being able to sleep properly. What worked for me was disabling "safe sleep" a la this hint.

sudo pmset -a hibernatemode 0
sudo nvram "use-nvramrc?"=false
Then restart. You can also remove /private/var/vm/sleepimage to save some space, which is nice.
