And here we go again with corrupt download files unable to expand

There seems to be a pattern with major updates from Apple and the ability of the servers providing the content - be it iTunes or iOS or Mac OS updates - I have been unale to download sucessfully the larger updates but smaller (22MB for AirPOrt Utility) work fine.

The annoying thing is that in almost all cases the erorr dosen't occur until AFTER the download is complete - meaning it takes up allt he time and bandwidth etc with no result and you have to start all over again.

This has happened to enoguh people and with enough different software releases that I posit that it is NOT the result of any partiucalr configuration of netwokring and or hardware and or firmware and or OS version etc - but that the it is a systemic issue on the provider side of things.

Perhaps they (Apple's content providers) should stagger access or something - by time zone - or Apple should release updates over the course of a week - not all on the same day.

I would much rather get a message that the server is busy try agian later - or have one update a day - and have it work on the first try - that to waste time retrying the same downloads over and over again.

All updates under 200MB in size are done across several machines - updates of 600MB and up are still failing in some cases - but whittling away at it.

Sorry but I done numerous updates to my Mac and never had a corrupted download. Did some just last night IIRC (or the night before) and had NO problems what so ever.

I'd look at another cause other then on the Apple side as if this was true there would be posts all over the net and in all the Apple/Mac websites about it.

While it is entirely possible taht some combination of DOCIS or firmware etc on the user end is a contirbuting facotr - it is not hard to find numerous reports of exactly what I am talking about along with other similar issues.

I don't recall having this issue before I upgraded to 50Mbps download service - so there could be a connection there. But the "solution" in my case so far has been to just simply keep trying and eventually it works just fine.

I suppose I may have forggotten as they are so few and far between - but in my recollection - the ONLY issues I have had have been with software from Apple - whether downloaded via software update - or the App store - or iTunes - and no where else - on both Mac and Windows (had Apple Software Update fail to get iTunes update a couple times on Windows, but windows is easy to goof up if you have other installers running at the same time).

On the other hand I don't recall too many cases in the past where the downloads were so large as they are nowadays - and certainly the number of users after those downloads has only increased over time.

I'm having trouble with the AirPort Utility ! That's on the MacBook Pro. Meanwhile the 2011 iMac has had to go to the service shop with a kernel panic from the same download. And -- And! Last month's big downloads and this one used up my allowance on the satellite broadband, dooming me to .8-.9Mb! I haven't tried the big files yet on this one. If 22 throws it, what will the larger ones do? Yikes!
