As someone recently employed by a Golden Arches franchise, I will attest to using only "table salt" to salt french fries. More specifically, I'd load the fry salting device from a 4-lb paper box of commercial non-iodized table salt [1].
If you'd like to verify this fact at your local McDonalds go ahead and order some fries "no salt" and do the salting yourself. As a bonus, you'll also most likely ensure you get fresh fries. Don't do this in the drive thru, as it's kind of an asshole move. 3:20 for fresh fries.
