In a frying pan, melt 1-2 Tbs. of butter. Add the apples with cinnamon and sugar to taste. Sauté until easily pierced with a fork. (They should be soft, but not applesauce.) Remove from heat and set aside.
Add approximately an inch of water to the bottom of a double boiler and melt 1 cup of white chocolate chips on medium heat. Stir every few minutes and be sure not to get any water in the chocolate. When the chips are melted, remove from heat and stir in 2 Tbs. of melted butter. Allow the mixture to cool for 10 minutes.
In a large, deep bowl, combine the somewhat-cooled white chocolate mixture, cream cheese, sugar, maple syrup, spices and salt. Use an stand or hand mixer to mix all the ingredients until smooth and creamy. Be sure to scrape down the sides of the bowl every so often to ensure that everything is well combined. Don't to use the slowest setting and do not over mix. Gently fold in the prepared apples.
Preheat the oven to 325°F. Scoop the filling in the spring form pan and using a small offset spatula, smooth it out until even. Sprinkle the struesel over the top.
Bake for 35 minutes, making sure to not open the oven! Any rapid change in temperature or humidity can lead to cracking and caving.
Turn the oven off and let the cheesecake rest in the oven for another 30 minutes, still not opening the door. When the time is up, remove from oven and let the cheesecake cool for approximately 30 more minutes before letting it chill and set up in the refrigerator for at least three hours.
