Profile Mountain Lion's startup Recently my Mac mini became quite slow without a real apparent cause. I'd really like to be able to trace down the cause of this slowness, and I'd like to do it myself, not using a program.

Is there a good Mac OS X resource website that could lead me to that?
Couple things to try:


Start in verbose mode (Command + V)


You'll see a narration of the start up processes.


Open Console and look at your logs.


There's lots of things that can lead to slow startups, but I'd be on the look out for permission and network timeout errors.
