Hello, Try the Mac OSX Unleashed book by Ray and Ray. It is a UNIX Superbible specifically for the Macintosh. About 1000 pages of geek stuff. Get the version that matches your OS. There is no simple language for under the hood. However, try the Missing Manual series (O'Reilley) for your OS if you feel intimidated [ see below ] by the Ray and Ray book. Actually, just go to your nearest Borders or Barnes and Nobel and browse the Macintosh section. Then browse the UNIX section. I know there is a Macintosh for Unix users type of book out. As you approach the Macintosh book section....SHOW NO FEAR....The Ray and Ray book can smell newbie fear from a distance of 3 book categories away...you cannot hide in the map section.... Other posters have listed some internet resources so have fun.... John F.

I am looking for recommended resources (have done the Google/search option) for simple language (ie non-programmer) for the basic behind- the scenes stuff in OSX. I would like to start playing in terminal to modify and/or understand what is happening under the hood. Any assistance would be appreciated.
