Directly from Apple's HIG for alerts:
When the most likely button performs a nondestructive action, it should be on the right in a two-button alert. The button that cancels this action should be on the left.
When the most likely button performs a destructive action, it should be on the left in a two-button alert. The button that cancels this action should be on the right.
So, I would assume that the most likely button is skip especially Skip is in bold in your screenshot (although you may think differently), which is nondestructive. Then, it should be on the right, and change will be on the left.
