Hence, very funny. good points from you guys.   Anyways the OP made a comment on us this forum.

I have read all the replies, and I sincerely want to thank those of you who took me seriously and gave good suggestions.  As for the rest of you, I really expected that hackers would understand what I'm going through.  At any rate, you put the kabosh on the book I hoped to write about my ordeal with being hacked.  If you can't believe it, how will non-hackers?  No wonder my children just believe I don't know anything about computers--so do hackers! 

I guess you could say I am giving up for now.  As long as you know I'm stupid now I might as well ask, "Google the OP" ??  Is OP like Tiger 10.4?  I did Google that and did find others that had been hacked into servers like mine. 

Who is Edsager Dijkstra?  That quote is fascinating.  I want to read more.

Finally, while I was enjoying my  Knoppix Live CD and was locked out of my OS by the hacker, I returned one day to find he had erased the disk.  Unfortunately the only disks I had to reinstall with were the two he had previously put scripts
on, believe it or not.   I could not uncheck the boxes where the scripts were and when I tried to install it with the scripts but without the 25 languages, 20 different printer drivers, and all the other crap he added onto the installation, it wouldn't install saying things were missing in the "Optional packages."  Desperate to use my own computer again, and hoping against hope that his erasing the disk was a farewell gesture, I let the whole installation go through the way it was, putting certain things in his private/etc. files and all.  I have since attempted to fix this using disk utility repair and verify, and by manually moving files around.

I looked around and thought he was gone.  Then I noticed the network was locked and once again I didn't have permission to open any part of it including the library.  When I press the option key while booting, this time I don't just see his scrawny disk that serves as his network but a big padlock.  Many other things are off limits and locked.   He has also managed to set up computer so that I can no longer get my Live CD's to boot by pressing C or Shift-Option-Cmd-Del.  Not even the install disk will boot.  I know in Windows this can be changed by resetting the BIOS.  In Mac, I haven't a clue and can't find one for how to change this.  Can anyone tell me?

I also called AT&T and the assholes want $120 to give me a new IP, preferably dynamic, even though the wireless hacker is using my AT&T connection as I write this.  They haven't the faintest shred of interest in my being hacked on their lines.  They offer no help.  They want another $120 before they will even discuss my problems further.

Should I just accept that this hacker has a perverted attachment to me and my computer and will be here until the RAM or computer dies?  Apparently he did get more RAM because the memory is fine now.  I am getting ready to revise my novel on it, and I need to add that file and my other writing files from my son's external drive. 

I found some old notebooks that showed that this same hacker has been on my case at least since January of 2008.  I only bought the computer that month.  How is that possible if the computer was really new from the Apple Store?

If you're sick of my saga, I guess I can't blame you.  I'm sick of it too.  I just want to write in peace and solitude and manage my own computer.  But I feel wiped out.  If I buy new installation disks, or install a Linux OS, lock up everything, get a router which I don't have now, pay for a new dynamic IP and get a new IP carrier, etc. who is to say that he won't come back?  I feel so f**king defeated. 

Can I get an encouraging word or have I used up my welcome?   Maryellen

You really need a professional. If you want this thing to end. It would cost you but problem solve. We really can not help you if keep on mixing up the technical jargons with using other shortcut stuff we are using... Till then MsRefusnik

Professional help means going an extra mile in meeting security professionals from Security Conferences such as Defcon; Shmoocon; or Bsides Las Vegas. They might help you. Mam  since your boot sequence is in first priority(CD) once you load in a Live CD which is Knoppix it would really boot CDs do not confuse yourself. I am begging you. Ask consulting firms.
