mavericks download stuck at 995mb

Tried to upgrade to Mavericks on 27" iMac Late 2009; download stuck at 995MB. Tried rebooting , pausing/resuming, standing on my head, coffee etc to no avail. Worked for my MacBook Pro and my 21.5" iMac but not the 27". How do I blow away the part download and start again?

iMac, OS X Mavericks (10.9)

@all:

5MBps is 50Mbps: fast enough (Bytes and bits).

Some providers have a 1GB data boundary.

If you have to download to more than one computer, download on one, then do not install, and copy the whole file ("install Mavericks") to the other computers Applications folders. Do not move it out of the applications folder!

Or you make a bootable stick with it before you install.

Same problem here and I'm on BT. At home I have Sky and it came through no problem. At work its BT and its the crappest ISP on the planet. Luckily we have another ISP feeding the office however its from TalkTalk (the second crappest ISP on the planet) and it too stalls at 995mb.


I'm trying the HotSpot sheild method as mentioned above as resetting the app store doesnt do anything.

It is not directly related to provider!

Apple use servers around the world, when you click download it takes you to the nearest server or whatever, and this is server related issue not provider, but when you use one provider it will take you to same server everytime. Changing provider change server you are connecting to.

Servers are probably used as a service (akamai for example), so this is not apple fault too.

Hotspot Shield works like a dream, and hardly any speed restrictions (at least for us) - thanks!


After a bit of digging online, it turns out it's the router. The BT 2701HGV-C routers are apparently notorious for not allowing large file downloads. I would hazard a guess and say if you're getting the cut-out at 995-ish MB, you've got a 2701HGV-C router (check the back for the model number).

I have had exactly the same issues using a BT Router, even connecting to my work VPN and a freshdownload it still got stuck at 995mb. Finally this time I connected afterwards as a last throw of the dice to BT Openzone since that comes free with my broadband and it immediately has continued downloading again. It has taken nearly 24 hours to work that out, I should have remembered this I had teh same problem last time with Mountain Lion.

I'm from Salzburg, Austria and have the same problem! I've tried 3 different computers in the office and everytime the download reaches 995MB, it stucks. But it always does not go that far! Most at the time, I get an error at the very beginning! We are at "Salzburg AG" at the office and i can't switch my provider! What to do????

I'm in the US, in New York, and I'm having an identical problem at my office. We have multiple bonded T1 lines here, but the download stalls repeatedly at 996-998Mb, and seems to try to resume at 986Mb. I've tried resetting the app store (which I hate with a passion) and wish I could just download the .dmg from some other source. We do not have restrictions on large file transfers with our ISP - we are regularly moving multi Gb files via FTP, DropBox, Hightail and other services, so I don't see why the crappy app store shouldn't be able to handle a download either.


I seem to recall I had this problem with the last OS too. I think I had to download the OS at home, on my laptop, make a .dmg, copy that to dropbox, and then wait for it to transfer to this computer. I'd take it to a mac store and have them deal with it, but I'm not unplugging this beast box - not a reasonable way to get service.


Anybody have any ideas why this might be hanging up, and what to do about it?
