As can TechTool Deluxe, which jowilly may have gotten along with AppleCare (If he purchased it).
Only if the Applecare was purchased a year or so back. TechTool Deluxe was dropped from Applecare sometime during the first quarter of 2011. Micromat had dropped all support for it some time before that. Using it in either Snow Leopard or Lion could be risky.
If we knew what it was we were doing, it wouldn't be called research, would it?
