Hello Everyone, My iPad Mini 2 (16GB Wifi only) is saying that I only have 579 MB available but everything I've counted doesn't add up. I plugged it into my Mac (Macbook Air 11" 2013 1.3GHz i5) and it said that it has 2.07 GB free. This can be seen in these two pictures. I need help as to why this is happening. Thanks!
