I already had Sky Safari 6 Pro on my iPhone and iPad but, had been using Sky Safari 4 on my Mac Mini. I really like the changes from Sky Safari 4 and there are lots of them. All my settings transferred over seamlessly from Live Sky which I already had in my setting on my iPad. The translucent earth is great, I like to see what is below the horizon before it rises. Overall it was a much bigger change from Sky Safari 4 to my pleasant surprise.
