Mountain Lion download stops at a certain point (79.34Mb)

I'm trying to download Mountain Lion. The download stops at a certain point (79.34Mb) and nothing I can do will restart it. I have followed the tips in the 'restarting a download' page and tried cancelling the download and it always stops and the same point. The purchase page in appstore shows a Pause button, but pausing and resuming doesn't restart the download. What can I do now?

HT202159 Mountain lion download stopped at middle.

Hi Everyone,
I purchased montain lion and started the download but at meantime it stoped and i couldnt manage start the download again, theres a error msg that says "an error has occured", great! what a suposed to do now!? does anyone had the same problem!?
thanks

I'm another who's had the 53.25MB failure issue, and it's 99.9% certain to be a router issue. If you're in the UK then the chances are you're with BT for your broadband. As mentioned above, there is a known issue with the 2Wire BT Business Hub, see link below, and probably other routers too.

"If you want Mountain Lion, or any other large download, then you'll need to get another router, or firmware upgrade if available." That however can be a pain, and if BT don't play ball then an expensive one. There is another solution however, and one that means no contact with BT, call centres or your local PC World ...
What I did was put in an old BTHomeHub that I had lying around to get it passed the 53.25MB point, and then paused the download while I reinstalled the 2Wire BT Business Hub. I then resumed the download and the whole 4+GB was on my iMac in a few minutes (well just over the hour). If you don't have a spare router, borrow one, you'll only need it to get the download passed the 53.25MB stage. For completeness, I waited until it was at about 150MB before pausing.
Hope that helps some.

HT202159 Download of Mountain Lion OSX stops

Cannot download mountain lion. Stops and shows no record of partial download.

I did that too...says there are no unfinished downloads. Also restarted my computer 3x. On that note, since purchasing it about 8 months ago...has only properly restarted 1 time!

Mountain Lion keeps stopping and recalculating download at 53.25MB - I have tried several times now, no joy (have new iMac May 2012)

Mountain Lion keeps stopping and recalculating download at 53.25MB - I have tried several times now with resumes and restarts, no joy (have new iMac May 2012). Any ideas, please?
Thanks, bb2804

In cases like this, if you have an Apple store near by, they will most likely install the OS free of charge for you, if you can't bring your Apple ID along to prove you've paid for it.
Would that work out for you?

Mountain Lion download problems with Lion 10.7.5 (no VirusBarrier issue)

I have a mid-2009 Macbook Pro. From the factory it came with Snow Leopard but has since been upgraded to Lion OS X 10.7.5. I do not have VirusBarrier, I am writing from a recently clean-installed Lion.
I have now been troubleshooting my Mac for several days. When I wrote first, I had an issue with Safari having been damaged and so I wasn't able to reinstall Lion - but after a certain extremely helpful community member I finally succeeded in installing Lion.
But the issues with the App Store still persist. All my Mountain Lion downloads fail, getting the error message "can't verify, might be corrupted" what many here have also been getting. However, most solutions were related to VirusBarrier (which I don't have), or /var/folders errors (Console does not show any var-related errors).
So if it's not a var-related issue, or related to firewalls or virus softwares (I have disabled the Firewall and I have no virus software installed), what could it be?
When the download and install of ML failed last time, Console showed the following messages:
11/30/12 11:54:44.617 AM com.apple.SecurityServer: Failed to authorize right 'system.install.app-store-software' by client '/System/Library/PrivateFrameworks/PackageKit.framework/Versions/A/Resources/in stalld' [235] for authorization created by '/System/Library/CoreServices/Software Update.app' [567]

It may have been corrupted or tampered with during downloading.}
...and a bit later, upon re-starting the download:

Problem elimination:
* I don't think this is a router-related issue: I have downloaded and installed other softwares outside App Store successfully
* As said, I don't think this has anything to do with Firewall or Virus settings
* Nor has this anything to do with /var/folders as far as I can tell
What I've tried so far:
* Repaired disk permissions several times
* Rebooted
* Restarted App Store
* Following one advise found on the net, I deleted preflight.pfpkg just in case
* All the time I have made sure my OS has the most recent Software Updates installed (most of them downloaded successfully, while with Safari and OS 10.7.5. I had to try several times before they were downloaded succesfully)
I just reinstalled my OS X Lion, only to use it to jump on to Mountain Lion - so I am pending my migration until ML is installed. I would like to fix this soon, since I'd like to get the migration done and my real work started. I would really appreciate your help.
I'm not very adept at using Console or Terminal to troubleshoot, so if someone could guide me through the problem identification, that would be great. Unless someone already knows exactly what's going wrong and can show me a working solution - that'd save my day!
Thanks!

How many machines can I install on with one Mountain Lion download?

I want to upgrade to Mountain Lion, but I have both an iMac and a MacBook Pro. Do I have to buy two Mountain Lion downloads - one for each, or can I somehow download twice after paying once?
Judy

Actually, having made the same claim a couple of days ago and being proven completely wrong, I have a certain responsibility to correct you by mentioning that there is no limit to how many machines ML can be installed on, as long as you own or control those machines.
See section 2B(i): http://images.apple.com/legal/sla/docs/OSX108.pdf

What to do when Lion download stops because of power failure?

Please, can anybody advise: what to do when Mac OS X v10.7 Lion download stops, because of interruption of power supply?

I would first try reinstalling your backup copy of your previous OSX version if you can and then try reinitiating the installation of Lion from there. However, if that doesn't work at all, then the stoppage of the download by the power failure most likely corrupted your harddrive. I myself would then take the safest course and reformat the harddrive by booting from your Original Installation Disks and reformatting the harddrive from the Disk's "Disk Utility". Then go thru the installation of the previous operating system to the point where you can once again proceed with the download and installation of Lion.
Hope this helps

HT4718 Can't find iLife after Mountain Lion download?

After my mountain lion download (done by a genius at the apple store so I know I didn't mess it up!), ilife isn't here. It's also not under the "purchase" section of the app store like support.apple.com says it should be. help?

New Macs come with iLife. However, if you did a clean install you're not going to have iLife.
However, the original install disk that came with your Mac should have an iLife installer included.

Slow internet after mountain lion download

web pages open slowly or not at all after mountain lion download

I'm having the same problem but only at home with a slow internet service. At work with faster internet my macbook pro works fine. I wonder if Mountain Lion requires some minimum internet speed? Our old macbook pro (not using Mountain Lion) still works fine with our slow home internet. This change happened when I installed Mountain Lion. Also I can boot from by back up disk and bypass Mountain Lion and work with my slow internet at home. ???

After Mountain Lion download, FaceTime is not working anymore. Any ideas?

After Mountain Lion download, FaceTime is not working anymore. Any ideas?

I have reinstalled mountain Lion again . This time, Facetime works when somebody calls me, and I can do calls from my Mac again. But the problem was still that I was not able to call my iPad, what I was able to do with Lion (I had one Apple-ID and two call adresses). The solution was this time to generate a second Apple-ID from the Facetime in my Mac (this doesn't affect your main Apple-ID, it's only used for Facetime). Now, it works! ;-)

My OS X Mountain Lion download was interrupted and now I can't get it to download at all.

My OS X 7 Mountain Lion download was interrupted and now I have a Mountain Lion shadow on my doc saying "paused" but I can't seem to restart the download

If the download does not resume, then Quit the App Store app and delete the partial download in your Applications folder. Then you will have to start the download all over again from the "Purchases" section of the App store.

Can I stagger the OS X Mountain Lion download?

Hello,
Can I stagger the OS X Mountain Lion download as long as convenient?

That depends quite a bit on the speed of the links between your computer and the servers sending the download. Your immediate link to the internet and the link from your modem/router to your Mac are ikely to be the slowest links.
Absent information about your link speeds, "hours and hours" is the best answer I can give.
