I was a Windows only guy for many many years and have been using Macs now for about 3 years full time for personal user and at my prior job it's all I used as well for work. I'm a Sr Systems Engineer however and still work on Windows servers as 95% of my day to day. I'm trying to understand the way things get called or added to be started up when OS X boots. I know in Windows for example, there are a number of locations this can be defined. There's a users start up folder, there's a system wide (all users) start up folder, there are spots in the registry, and there are services. I'm looking to understand at that kind of level but with OS X where any an all daemons (services) and apps get called to start on boot so I can get a better understanding of what's happening and ensure there aren't items that I do not wish to start with the OS each time. Maybe there's even a built in function to find this out or a 3rd party app that makes seeing this info and managing it easier. Thanks!
