Why do Mac Appstore updates change file size when downloading?
I was updating iMovie to the current version 10.0.3
When it was downloading, it went
from: "downloading 100 MB of 200+ MB"
to: "downloading 300+ MB of 1.97 GB"
Why does it do that? The same thing happens when I'm downloading iPhoto, Keynote, Pages & other Apple apps.
MacBook Air, OS X Mavericks (10.9.2)
