Thanks for the response and research, Zingo 156.
Regarding resetting NVRAM / PRAM:
I did several times. No effects other than what is expected.
Regarding, "Can you go into more detail about this: 'I'm terrifed to work on anything worth saving because the files change -- additional text when writing'":
I'm not a writer, yet I know that 'editing is writing', and I write to sketch ideas. Additonal words, altered spelling, and other odd occurences appear when I review my writing after saving. It's as if someone has access to my files and edit my words to discover later -- like a prank.
Regarding firmware updates:
The laptop was updated to 1.7. I called Apple Support, and they informed me that the firmware cannot be reverted once it is updated. I thought about the 'Firmware Resoration CD', however the laptop will not boot from the USB in this instance. Furthermore, I cannot find any information about 'flashing' the firmware, especially a mac; I hope that an Apple Genius can restore the firmware from scratch.
I've also read about that 'rootkit' or whatever it is. There are many mixed opinions about it's validity or accuracy.
Regarding a CD version of 'Linux-Live':
It's a Macbook Air -- no DVD/CD/Optical drive.
Does anyone have ideas about using what exists on a 11" MacBook Air and create a new or custom 'firmware', UEFI code, or whatever? Any hackers who have some experience hacking MacBooks beyond root-level?
