The main thing is that magic draws from a living being, primarily Metahumanity, to power itself. Machinery lacks that arcane power so can't harness it. Shadowrun does have enchanted items, but, in this case, they draw on the wielder's innate power as well... there are no generic magic swords or magic boots or magical frying pans that can just be turned on and do stuff … they only work while a person, who already has magical power, can wield them. So, magic boots on amagician do things, magic boots on a mundane do nothing, and magic boots stuck on a robot are also not doing a thing.
There have been a few things which "cross the streams" a bit by getting clever... there's a camera which can photograph spirits, for instance, and that camera can be mounted in a drone to allow *it* to get pictures of spirits … but spirits don't show up on normal camera feeds, so if you're remotely piloting a drone, it can fly through a hundred ghosts and you'd never have the slieghtest idea.
It's all backed into the way magic works in Shadowrun.
