I'm typing this on my brand new 12" PowerBook, and I must say I'm impressed. However, I am used to Linux/Solaris/*BSD, and was wondering if there was some kind of guide or FAQ that details what's different with OS X compared to other UNIX-type systems. Like, what is the root password? Where do my personal preferences get stored? I installed Firefox, and went looking for my .mozilla folder but couldn't find it. Basic stuff like that is what I'm looking for. Thanks.
