Catch Applin, evolve it into Dipplin and Hydrapple, and collect Syrupy Apples during the Pokemon GO Harvest Festival event.

You can find Applin in Pokémon Go, though you’ll need to look for literal apples on the floor. We explain how to find the apple Pokémon and evolve it.

You can't run iPhone apps on a Mac computer without an emulator, though that will change with a new set of Macs, coming out by the end of 2020.

Your iPhone apps should update automatically, but if they aren't, you can check for updates manually through the App Store.
