What is mdworker?

I don't know why my Mac book pro is working so slowly. I wondered if I had somehow gotten MacDefender downloaded and realised it was malware... I couldn't find it in the Applications but I did find mdworker. I don't know what that is. Could it be related to MacDefender?


I am very frustrated with the performance of my Mac recently and I don't know what to do about it.


HELLLLLPPPPPPP!

mdworker is system software that takes care of spoltlight indexing. it's perfectly normal, and if this is a new machine (or a machine you've just added a lot of files to) then mdworker will be busy for a while indexing. best thing to do is to leave your computer on for a couple of hours and let it get done, and after that it will only pop up occassionaly to deal with new material.

It sounds to me as if you need to reset the SMC (System Management Controller).


The SMC has nothing whatsoever to do with the mdworker process. Resetting it makes no sense in the context of this discussion. Further, note that you're replying to a topic that is more than a year old. The person you're replying to has not posted anything here since that time, and is probably not still here.
