HT202159 Mountain Lion download problems

I have tired to download Mountain Lion twice. The first time the download just froze. The second time, in the App Store 'purchases' secetion, place of the "RESUME" tab, it says "An error has occurred". I have the option to BUY the app again, but am afraid of getting charged again. What can I do?

It is a BIG problem....
I am trying to download it, but is becoming a undesireble thing.
Once, it gets an error, or it says that the file is corrupted, or it says that and I have to log in and it starts all over again from the begging.
What a huge BUG.
Apple should try to correct this

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:
11/30/12 12:29:40.515 PM com.apple.SecurityServer: Failed to authorize right 'system.install.apple-software' by client '/System/Library/PrivateFrameworks/PackageKit.framework/Versions/A/Resources/in stalld' [817] for authorization created by '/Applications/App Store.app' [781]

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!

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?

HT1338 Mountain Lion download problems

Tried to get Mountain Lion download/install on my computer. Got message "An error has occured" so can't download. Computer is up to date with plenty of space.

Went to Genius Bar. Solved my problem but I'm not sure how helpful. He ran some diagnostics (hardware diagnostic progeam; Mac Disk Utility for Hard Drive Verication and repair. Don't think he found much wrong. Then, he went for download on their connection, which worked just fine. He explained it was because of the extremely fast download connection. So, I guess you have to get your Mac to somewhere with a super-fast connection (Apple store, but also our local libraries have a very fast connection) for download.
That's all for this problem, as far as I can tell. Over and out.

HT202159 OSX Mountain Lion download problems

Hello,
I have been trying to download OSX Mountain Lion from the appstore on my 10.6.8 mac mini but the file stops downloading after about 10mb. I was able to download 10.7 without any problems but I am not able to downlaod 10.8 on either of my two machines. Both stop at about 10mb. Anyone seen this or have any possible solutions?
Thanks!
Travis

I have seen this, unfortunately there are 100 & 1 different things that can cause this. If you want to trouble shoot, let's power-cycle both your modem and router and see how that goes.

Mountain Lion download problem

I have been trying to download Mountain Lion for about 5 hours now and I keep getting errors saying the download cannot be completed. The last error I recieved was The download could not be completed becasue of a Hash Mismatch Error.
A download of about 4GB of data on my Internet Connection would usually take about 1 hour.
If I do get to succesfully download the Installer will the Installation begin automatically or is it started manually. I would prefer manually so I can make a backup copy first.

I am on a Late 2011 13' Macbook Pro, OsX 10.7.5

Contacted Apple Store Tech support requesting a solution. I received a reply from a gentleman telling me his area of expertise and that this problems didn't fit in his area of expertise and suggested I look on online forums and the like for a solution!!
All I have found out is this is a very common problem
Thanks for http://www.apple.com/support/mac/app-store/contact.html?form=account. Have not received a reply from Apple after 48 Hours.
I have tried:
Logging out and back onto the Online Store
Deleting the Apple Store cache on my HD
Connecting via an Ethernet cable instead of WI-FI
Using my iPhone 3G Data, teathered
Connecting via a totally different network
Restarting, restarting, restarting...
Nothing has worked. And still no solutions from Apple. I kinda of thought they might have suggested I go into a real Apple store and have them put a copy on my Mac or something.

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.
http://btbroadbandandhowtosurviveit.blogspot.co.uk/2012/08/bts-2-wire-woes.html
"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 Mountain Lion download stalling at 53.25mb

I am running an iMac 10,1 with Snow Leopard 10.6.8 and purchased Mountain Lion yesterday but the download stalled at 53.25mb. I have sufficient Hard drive space and Wifi signal but it won't go any further. I tried re-lanching the App Store, then re-started my Mac and then finally stopped the download and started again but it got to the same point and stopped.
Any help would be much appreciated as I have exhausted all avenues I can think of.

Mountain Lion download problems

I have a mac pro (early 2011). I'm trying to install Mountain Lion. The download goes for a few minutes and then stops and will not continue. I'm confident my Mac will support Mountain Lion- Mac OS X Lion 10.7.5 is the version I currently run. Any advice?

This has worked for some people
- Sign out of the App Store (in the Store menu)
- Quit the App Store
- In Finder - Go>Go to folder... (or Apple-shift-G)
- Paste in the following "~/Library/Caches/ "
- It will take you to a folder. Delete com.apple.appstore
- Launch the App Store. Sign in and then reclick the Mountain Lion buy. It won't charge you again.
Another option is to boot into the Safe Mode to try and download it.

HT202159 Mountain Lion download not resuming

I tried to download Mountain Lion with the free up-to-date program but was interrupted. I tried to download again the next day but got this message: "The product distribution file could not be verified. It may be damaged or was not signed."

Quit the App Store if it's open.
Open the Finder. From the Finder menu bar top of your screen click Go > Go to Folder
Type this exactly as you see it here:
/Library/Preferences/SystemConfiguration
Click Go
Move the NetworkInterfaces.plist file from the SystemConfiguration folder to the Trash.
Relaunch the App Store and try downloading Mountain Lion.

HT202159 osx lion download problems

Mountain Lion download getting stuck at 79MB w/ no internet connectivity issues

I just purchased Mountain Lion via the App Store but everytime I try to download it, the download gets stuck around 79.4MB and the download time just gets longer and longer without the download actually pausing. Pausing and resuming have the same problem, the file size just goes up to 80+MB before dropping back down to 79.4MB again. I have tried canceling, reopening the App store and re-downloading several times already without success. Please help! I went through Mountain Lion download problems in the forum but I can't find a solution. I'm downloading onto an iMac on a broadband Wifi personal home network and can surf the internet without problems and as quickly as usual. For reference, my connectivity speed at this time is usually enough to download a 300MB file in 15 mins to half an hour.
