How to save a ref variable for later use?

Question

So this works..

public MyClass(ref Apple apple)
{
    apple = new Apple(\"Macintosh\"); // Works fine
}

But is it possible to do something

Answer 1

Why not just have ModifyApple return the modified Apple instance?

public Apple ModifyApple()
{
    myApple = new Apple("Macintosh"); // does not change the input variable like the first example did
    return myApple;
}
