729MB download reveals changes below the surfaceTuesday's release of OS X 10.5.7, the latest update to the Leopard operating system, weighed in at 449MB on my MacBook Pro; the combined updater (which will update any version of OS X 10.5 to 10.5.7) is a whopping 729MB. Even on a super-fast FIOS connection, it took about a few minutes to download the update, and quite a few more minutes to install - it seems that the “writing files” step takes longer and longer with each update.
