New to OS X, but I need to write an app that records activity

activity logger, versus a keylogger. I'd prefer not to go to as low
a level as a kernel extension,
Sounds like you could do this with the event tap and window facilities
available in CoreGraphics (CGEvent.h for starters). Look here <http://prefabsoftware.com/

as I'd really like to keep this in user space (but I will, if I have
to). I've done the same thing in Windows (using hooks) and Linux
(X11 using the XRecord extension to the X server), but I know little
or nothing about Quartz, Aqua, Carbon, kernel extensions, etc, etc,
so I'm asking for guidance as to the right layer to target and
technology to use. In the X11 version, the monitor loads from the
Xsession config - that is it starts when the user logs in and runs
only while the user is logged in... ideally I'd like to mimic that.
Can someone with more experience on OS X features give me some
pointers?
Btw, I know this isn't specifically a kernel question, but I figure
the kernel guru's would know best when something shouldn't be done
in a kernel extension. If a kernel extension is the only way to do
it though, then that's the way I'll go.
