Looking at the docs for fileSystemAttributesAtPath, it seems probable that your 4700MB overflows 32 bits worth of unsigned int, if units are bytes.

Then, the high-order stuff having OF'ed out, you might be seeing that
788MB == (4700MB) % (1 << 32).

That doesn't seem to be "quite" mathematically correct, though I'm guessing there is lots of rounding/estimation error in the figures you supplied.

Taking into account the large sizes of modern disks, perhaps it should be upgraded to unsigned long?
