Blank process name in Activity Monitor on OS X Mavericks

Solution 1:

Try clicking the "info" button and then running a sample on the process. For me, the process turned out to by iStatLocalDaemon.

Solution 2:

I usually have process like this on my "Activity Monitor" too, and there is no additional information related to it when I push the "Info" button.

First I get the PID showed at the "Activity Monitor", in your example, is

31602

In my case, it was the 725 PID.

I went to the "Terminal" and looked up for that PID manually, using ps command:

ps -ea | grep 725

The result was:

  725 ??         0:00.13 com.apple.activititymonitor.helper

Now I have an idea about what the process without name is :)

I hope this can resolves your doubts.

Best Regards.
