Not reliably. You might infer that Ctrl-Alt-Del has been used by the way
that certain operations behave, but that's fairly error-prone.

I don't know about Mac. Linux has some support for Ctrl-Alt-Del on the
console, and the optional "Magic SysRq" feature. But there's no easy way
to detect these (if the sequence is recognised by the kernel, it's not
reported by the usual mechanisms).
