I'd like to know the list of places I can check through to see what programs are automatically starting when I boot Mac OS 10.6. I installed a handful of ports a long time ago on this machine and haven't used it in quite a while, and I want to use Apache HTTPd 2.2 that was installed through the port--NOT the installation that came with OS X. Web Sharing is turned off, but the default installation still starts at boot.
I'm not just looking to find out why this installation is starting--that's only part of my question. I'd also like to know the best method of checking when and where various executables are kicked off at boot time.
