Caching server only caches it once one client downloads it first directly from Apple, so that may be why its not cached yet, or it may just not be working.
EDIT: I stand corrected - https://jamfnation.jamfsoftware.com/discussion.html?id=11827 - nice going Apple!
Anyway, 5.7 GB, 6.9 GB. Apple needs to find a way to slim down these updates. No wonder Apple released new iPhones with upped storage. Heck, even full OS X installs typically don't come that big? What did they include in this update?
That said, I wonder if it actually uses all that space or just requires that much during the install (as it moves stuff around, expands install packages, etc) and then releases some of that later. Anyone know?
Agreed. I thought that was a strange decision too. I suppose they want to keep a very low end model around that someone who doesn't plan on ever adding a lot of apps, music, photos, etc to available. But I sure wish they had bumped them all up across the board. I agree 16 GB is just too small now, especially because we can't expand the space with anything external.
When I got my iPhone 5S late last year I opted for the 32 GB model, because I was constantly wrestling with space on my previous 16 GB one. Even so, I will STILL need to clear out some stuff on my 32 to make room for this update at some point. Ugh...
