I have a .dmg on my website for a Mac Software, but when i try to download this (even in different browsers), it doesn't show me the duration or the filesize. Could this be something i need to configure in Apache?
I checked the http header:

Try to add this to your .htaccess :
SetEnv no-gzip dont-vary
