Have you tried running "top" in Terminal to see if the process
names show up there?  This will give us a little more information
on how deep the problem goes, and it is also a partial substitute
for Activity Monitor.  You can read about it at

<http://developer.apple.com/documentation/Performance/Conceptual/PerformanceOverview/InitialEvaluation/chapter_5_section_2.html >


You could also try these things, in order:

Try logging in as another user or Guest, and see what happens.
If Activity Monitor works for other users, see what startup items
you have running.

Ordinarily it doesn't do much good, but this looks like a good
time to launch Disk Utility.app (in the Applications/Utilities
folder) and verify your hard disk and repair its permissions.

Boot into Safe Mode and see if the problem persists there.  If
Activity Monitor works there, then the problem is most likely
due to a kernel extension you added or a startup item.

Finally, you might try updating/reinstalling/uninstalling Audio Hijack,
since it reportedly has caused various bizarre system problems.


Give us more information:  which version OS X are you using?
Have you done any system "enhancements" besides Audio
Hijack, such as Application Enhancer (APE) from Unsanity?

Subject: Process name (null) on OS X

There is a curiosity I've noticed lately. Beside the symbols for the
Thunderbird, Sunbird, and Audio Hijack applications in Activity Monitor, it calls the process name (null) instead of their names. These apps seem
to be working properly and quitting them a restarting them does not
help. I did a little Googling and did not find anything helpful except
that the system is not recognizing their names.
Does anyone know what's going on?
