Anyone up for some Apple-puzzles?

Well, if you are, then maybe you have already heard of MacHeist. Every week or so you get a challenge to complete. These challenges aren’t easy but also not too complicated. If you manage to open the vault you get some Mac applications that would have costed you some bucks. This week you can get Cha-Ching and 1passwd. Even if you don’t need or want the apps, the puzzles can be quite challenging. So give it a try, there are only 4 challenges left!
