I can't remember how I originaly got a hold of them as I've had them a while but try these suggestions as search criteria within LW (look for PDF's in particular):

1. mac osx tips
2. mac osx
3. macosx
4. mac osx.pdf
5. macosx.pdf
6. mac osx bible

I'm sure you get the general idea. I got reasonable results with all of those. At least one good result from each!
