Every weekend, I got this process running on my mac, and it just use up all my cpu to run it. I really upset by it... Can somone know what's going on..?
I don't think it's normal at all...

It's probably a normal maintenace task... btw where did you see this '(null)' process? It doesn't looks like a process name... what does top show in terminal when this happens?

[Big Mac]

It's the Classic environment run amok. Activity Monitor identifies it as null for some strange reason, whereas top shows it as TruBluEnv. Just kill the SOB.

I've run into a "(null)" on my TiPB as well before, and it's happened when Classic has been disabled as well. Also, I've seen the True Blue in the Activity Monitor before, so I'm guessing it could be any number of other things. I used to get null processes all the time when testing my code for some of my computer science classes...just sloppy coding. Anyway, the Classic environment is certainly not the only cause of null processes, so it could be something else.
