Calm down, I can fix that

Grandma needs help with her computerizer again.

Aren't Shikagamis compared to computers? That said Ran would definitely kno what to do

But Yukari's supposed to be the uber-mentat who "programmed" Ran. Wouldn't she be way better at this than Ran?

She's the gap youkai, the mistress of vagueness and ambiguity. A functional computer, hell, a smartphone running through its bread and butter algebra with the strict definitions and absolutely defined correct solutions is probably like a warding field against her. Don't forget, she also can't stand Shiki's presence for this reason.
Now, a quantum computer would probably be more down her alley.

When you can program ai capable of programming it's own but not a pc....the pc's probably a mac

"Have you tried turning it on and off again?"

Seriously speaking though, I have no idea what's going on there. It doesn't seem to be the "blue screen of death" thing as far as I know. Can anyone tell me what happens there?
