I cant find this is the rule book but it may be there. but mechanically speaking how do I as a GM factor this in?
I assume this would be consistent but higher probability when considering a wizard compared to a minor talent.

Spellcasters affect technology. Treat it as a compel if you're trying to make their lives difficult, or just a skill check if they're doing it deliberately. (A very easy skill check, as I recall the chart).
If you're talking in terms of non-spellcasters hexing stuff? Doesn't happen. It's pretty explicitly tied to the spellcasting powers -- ritual and channeling, thaumaturgy and evocation.
