Resolved Mountain Lion.app different sizes?

[duramo]

I have two Install OS X Mountain Lion.app which both were downloaded from Mac App Store. But their size in bytes are actually different (by 9 byte) from each other when I get info. Does it mean something wrong in one of them?

Obviously one of your mountain lions has an overbyte.

Here're mine:
4,370,518,930 and 4,370,518,939 bytes.
I think there are usually a few bytes difference.

I found what is causing difference. Actually _MASReceipt folders in app files are different from each other by 9 bytes (in my situation). I think this is Mac App Store certification thing. So there is no wrong in dmg file.
