What you do is send a demand for payment via registered/certified mail with signature required to prove service. If they fail to pay, you haul them back to court for an examination of assets. If they fail to show up for that, then the court will cite them for contempt and now what was a civil matter will have expanded to a criminal element.
Whoever signed for the originally served papers at Apple's corporate HQ will be deemed as an authorized person to receive such communications. If they want to claim their own internal bureaucracy has problems, that's on them. You did your part.
Keep track of any additional expenses involved in collecting the debt as you are entitled to add that to the bill as well. You should also look into whatever interest the law of Minnesota entitles you to as well.
You should have 10 years to collect the judgement and you can file for an extension of the time if need be. Since Apple has assets, you should be able to collect. The only problems I encountered with successful judgements was in trying to collect from people who had nothing to seize, attach or garnish.
I've never dealt with the sheriff in collecting a small claims debt so if you go that route, you'll have to see what their policies are. All I know in a general sense is that one of the powers of a sheriff is to seize property to satisfy judgements. You can try that road if you like!
My information is based on business law classes taken in the mid-1970's in Oregon and on experiences from collecting debts for a small business I worked for shortly after that. How Minnesota works and how things are done today is unknown to me, so don't expect everything I say to be relevant to your case. All you're getting is what I know and it's "old knowledge".
