I am pretty sure it is run by the encryption chip, in point of fact. I
can't find the documentation on it though. Regardless, it is run by
cycles that would otherwise be idle. So, zero cost.

Your ignorance on the definition of ad hominem is quite spectacular.
Calling an idea stupid is not an ad hominem attack.

Anyway, I'm done with you. If you continue to post stupid hacks, I will
continue to reply to them warning others not to try them, but this
thread has passed the point of anything useful. Feel free to fuck up
your own computer however you want.

Don't you have a bit of a history of having weird behavior on your Macs?
Strange problems no one else has?

Hmmm...
