I have a Mac Book Pro, first generation. It is running 10.6.4. I usually keep it running. I put it into hibernation mode (i.e. it writes the state to disk and powers down) when I need to put it to sleep.
I have a ~100GB hard drive. Now I only have about 3.5 GB free. I've noticed that recently i get the low disk warning quite a bit and when I check sometimes it dwindles down to a few MB. I figured that it might have been my browsers (Chrome, Safari) caching stuff. I clear the cache and it frees up some space. But I never get back to 3.5GB.
So, I decide to shutdown and restart. Every time I do that I see that indeed I get back to about 3.5GB free.
My question is how do I figure out what is slowly eating up my disk space? Have people out there experienced these symptoms? What was the cause and how did you deal with it?
