I can't find this on the interweb or on this site using search terms like boot or startup, so... I am looking for documentation of the el cap boot process. I have a general interest in the technical aspects of it, and am specifically wanting to learn where to look for all the startup items to make sure my box does not have anything running on it that I don't want. I have a mac internals book from some years ago, but I understand that newer releases of osx are changing the way automatically started items/device drivers are loaded. A variation of this question is what would be a good utility to identify and maintain startup items--preferably free. I am familiar with such utilities for windows, but not aware of the mac equivalent. Any information along these lines is much appreciated.
