I run the latest OS X Lion on my MacBook Air. Whenever I put it to sleep and then wake it up it eats up a lot of space.
I believe all this space goes into the system cache which then again I keep deleting via OnyX. This again makes it impossible to reboot properly. If I reboot after completing a cache cleaning via OnyX then everything starts crashing: browsers, every application.
Then again I reboot and things work fine.
How do I avoid this space being eaten up? What tool is safe to use to free up this cache space?
pmset -g | grep hibernatemode
when run from a Terminal?
