OSX Mountain Lion not installing

Not sure if this maybe an issue (due to the network) but i am currently working in Iraq and downloaded my copy via a hotspot provided by the company. After installing my macbook keeps on asking me to restart. Had a look on my HD and saw the following
I have update all my software and time machine is switched off - just as a precaution. Any help would do, Thanks

1. Uninstall Virus Barrier X6 following this link
2. Delete folder com.apple.appstore from /Private/var/folders/rx/...../C/ or /Private/var/folders/.../C

Osx mountain lion not downloading

My download of osx mountain lion gets to 142mb then stops! I've tried deleting the purchase and redownloading still the same thing,
does anyone have an answer for this annoying issue!

Hello, how much free space on your Hard Drive?
Could be many things, we should start with this...
"Try Disk Utility
1. Insert the Mac OS X Install disc, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu at top of the screen. (In Mac OS X 10.4 or later, you must select your language first.)
*Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*
3. Click the First Aid tab.
4. Select your Mac OS X volume.
5. Click Repair Disk, (not Repair Permissions). Disk Utility checks and repairs the disk."
http://docs.info.apple.com/article.html?artnum=106214
Then try a Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.
(Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive & clear caches.)

Mountain Lion not installing on MacBook pro 17inch

I have downloaded without any issue and followed the prompt to install. The install start and goes on for 35 minutes with the progress bar moving. So it is doing something. Then it is getting to the end with the following message: install failed. OsX could not be installed on your computer. The installer encountered an error that caused the installation to fail. Contact the software manufacturer. Click start to restart your computer and try installing again.
I have tried 6 times but not working. The I wanting to restore from backup using the utilities from the menu bar "Restore System from backup" it will do the same and. Go on for 35 minutes and get to the same screen "install failed" what should I do now.

Having read several posts on this subject it seems to be very hit and miss for some people, but I think on the whole it is only a few who are affected.
I find it very difficult to believe that a Mac cannot be taken back to Snow Leopard by performing a complete fresh install using the install DVD that came with that machine, or a retail edition disc. Mac OS does not alter the firmware during the install as far as I am aware, so the hardware should be the same as it was originally before the install.
The only thing I can think that might prevent a successful install might be if the system files have been altered by software installers, the Mac OS installer might be confused, or if the permissions have not been set correctly then the installer might not be able to overwrite or set up certain files. That is why a clean install should (in theory) always work on compatible hardware, then a restore from a backup or Time Machine would be all that is required to bring back the user's data. Formatting the hard drive may be a necessary step if it is not working as expected, this can be done from the Utilities when booted from the install media (or Lion recovery thing).
I didn't have a problem installing Lion or Mountain Lion on my Late 2011 17 inch MacBook Pro, but before installing made sure I created a USB flash drive (8GB) from the downloaded installer using the little trick which is around on the internet. If the installation had bailed for any reason, I definitely did not want to have to download several GB all over again.

Mountain Lion not installing on 2009 Mac Mini

I have tried a few times to install the new Mountain Lion OS X onto my 2009 Mac Mini. I have gone through the basic checklists of what to do prior to installing but the install keeps on getting stuck after the original download and restart.
Once downloaded and the install process has begun it restarts and then the OS X install screen apears and it shows how many minutes it will take to install.
It remains at 34 minutes, the second time I attempted an install I left the computer on overnight to make sure it wasn't installing very slowly, it was left on for over 12 hours but did not advance in the process.
Details on the computer:
2009 Mac Mini
Software: version 10.7.5
Processor: 2.26 GHz Intel Core Duo
Memory: 4GB 1067 MHz DDR3
Hard Drive Space Available: 52.26GB
I have viewed many other problem threads here based on installing Mountain Lion and the hard disk having problems. My computer will just not advance past the very beginning of the install and I am able to reboot the install disk and retry or just go back to OS X Lion so I can use the computer again.
Anyone have a tip or something I can look into to see what may be the problem??

Found this elsewhere after a couple weeks of searching, inserting an old install DVD worked;

Mountain Lion not installing from Recovery HD

Ok so I want to restore my mac so I enter Recovery HD and when it's erasing Macintosh HD, I go to reinstall OS X, so I continue, agree to the terms and conditions, select my disk, and sign in into my iTunes account and then nothing, I try hitting install again and again sign into my itunes account and then nothing happens and this just keps going on. I tried restarting more than once, I also tried booting into my Time Macine and almost the same thing happens, I boot back into Recovery HD and try again but again nothing. Keep in mind that I downloaded Mountain Lion 3 times before plus the one more time that I restored so I guess maybe making that 4 times. I dont think I exceeded my maximum downloads since I didn't get a message telling me that or asking me to buy it another time. Keep in mind that I don't have access to another mac and that I don't live in the USA or any country with apple stores although I can go to an apple authorised reseller however my warranty is over. I was thinking of buying a Lion USB thumb drive and booting into that and installing Lion but will that work since my recovery HD is on Mountain Lion. GUYS URGENT HELP PLEASE!!!!!!!
And I also can't restore from time machine since I don't have a full system backup.
Thanks in advance!!!
MacBook Pro 13inch Early 2011.

Now when I go to Reinstall OS X, I get this message:
"Could not write installation information to disk.
please contact applecare"
Almost exactly that message
Help Please

Mountain Lion not installing on macbook, unable to start up now

So I downloaded Mountain Lion intending to use it for my iMac and Macbook Pro. I downloaded it fine on the iMac no problem. But when I went to install ML on my macbook pro, I pressed the button to install it on my hard drive from the ML installer and the button wouldn't take me anywhere, click after click. It just sat there. So I thought re-installing the installer might have been needed but the app store wouldn't recognize that I am logged on so I couldn't re-download it. So I thought restarting my computer would help but it's stuck on the white screen with the apple icon and the little loading circle in perpetual motion. It's been like that for half an hour and I have no idea whats going on. Did ML crash my computer?

Mountain Lion not installing - With VirusBarrier X6

I was having lots of problems trying to install Mtn. Lion but was able to install other apps and updates. I just couldn't figure it out! But with lots of support from Apple and searching around I was able to get it to work. I wanted to share to help everyone out!
First off, this only works if you have VirusBarrier X6 (VB)!
1) Open VB and click the tab "Surf"
2) Under "Surf" click "Ad Banner Filter"
3) Turn this OFF
4) Now turn OFF the computer.
5) Holding SHIFT, start the computer WHILE STILL HOLDING shift DOWN.
This will put the computer into Safe Mode. Safe Mode will clear certain Cache files that a user would not be able to normally to clear.
6) Release the Shift key when you see the gray Apple icon and the progress indicator (looks like a spinning gear).
7) Log into your account.
8) Now restart the computer NORMALLY.
9) Go into App Store and you should be able to download Mountain Lion.
I hope this helps!!

You can try this link, it worked for me:

The last one was what did it, moving the preflight.pfpgk to Trash

Mountain Lion not installing

Mountain Lion seemed to download OK but during install, the whole process disappeared after selecting MacHD as the volume. Can't find any trace of MLion on my system. After leaving it all night, tried restarting and re-downloading. The App Store says it is downloading but no sign of it on my desktop.

Thanks for the reply. The app was nowhere to be found but I tried downloading for third time and everything installed without a hitch. Go figure!

HT1338 Mountain Lion not installing

From the apple app store, purchased Mountain Lion. The mountain lion app icon shows download, but when I click down load nothing happens.

The issue is resolved.
Went to the app store and took the option to show my purchases. There it showed that that the down load was paused. Why it was paused is beyound me. Just restarted it and the download completed.
Before starting the installation I then made a back up copy of the install.dmg app and copied it to my other Macs so I didn't need to wait for the down load on the other computers.

How to download but not install OSX Mountain Lion on Mavericks

Hi all
I would like to download but not install OSX Mountain Lion on my MBP which is currently running OSX Mavericks.
This however seems impossible. I think OSX Mavericks were already installed on my MBP and therefore it seems "impossible" to download it.
Now, why would I to do this? The answer is quite reasonable, due to certain demands related to an application portfolio I need Mountain Lion, because the portfolio is not upgraded to run on Mavericks. And, it is more reasonable to downgrade a version of OSX, rather waiting for the portfolio upgrade which can take years.
Yes, I need to downgrade my secondary MBP which also came with preinstalled Mavericks. This can be done, if I only could download but not install Moutain Lion.
It should be easy enough; download Mountain Lion, make an installer and make a bootable thumb usb stick. Then erase Mavericks and install Mountain Lion.
I have previously bought Mountain Lion so it is accessible to me in the App Store, but whenever I try to hit the Download button, I get a message saying this can't be done, since I am running Mavericks.
This bugs me, it should be obvious users needs the flexibility to swap whatever OSX version they need. It is still software.
So, how can I download but not install Mountain Lion on my newer MBP that came with preinstalled Mavericks?
I would like to see answers like:
"In order to get this to work, you first have to disable the locking mechanism in [...] " instead of "No, this is impossible to do"
Regards

Thanks for your reply Eric
Can't help wondering thought, people are ok with this?
Basically Apple are saying: "Do not attempt to install an older version of OSX which came preinstalled. If so, expect multiple failures." Really?! Has it always been so? For me it's not like I'm going to install Snow Leopard on my Late 2013 Retina MBP, but I would expect some form of backward compatibility between the previous version and it successor. Apparently this is not possible, and how is this even acceptable?
Personally, I am not going to downgrade, as if I had a choice, but I would and I expected however, the possibility to at least download the previous OSX version. What do you do if you have bought several applications, not necessarily online from App Store and buy yourself a new Mac with preinstalled Mavericks and after installing your "old" applications they fail to work properly? What do you do since downgrading apparently is not an option. So... again, what do you do?
If you don't have friends with an older Mac, you could be facing serious problems. And I'm not talking about gaming, but serious business.
I find this quite disturbing actually, and please tell me it's not so. There gotta be a way to do this?
I simply want to download the OS but I expect some registry values (like windows' registry) keeps preventing this.
It should be possible to simply download and not download and install in one operation, shouldn't it?
Regards

HT1338 my macbook is not installing the osx mountain lion update, says contact apple care?

Ive been trying to instal osx moutain lion on my mac book pro, but its says installation fot this machine can not be found contact apple care? how do i go about installing osx mountain lion.

Mt Lion will not install on all Mac's. There are some that can run Lion but can not run Mt Lion. You may have one of those.
How are trying to do the install. Need more info on the Mac you have and how and where you got Mt Lion.

HT1338 I just installed OSX snow leapord and just want to be able to use icloud. I up--graded my old macbook to 2 gigs and still can't get it to download icloud . would go to osx mountain lion but can't do that either. What do I have to do???

I want to use icloud to sync w/my new apple tv. bought osx snow leopard and installed it plus upgraded to 2 gigs memory for my
old (2007) macbook. still won't work. I need to get to at least osx 10.7.4 or to osx mountain lion. Tried everything and can't get there.
I'm not a computer whiz...quite a novice. so, if you can help; please speak in layman language....ha   Thanks

iCloud requires 10.7.2 or later.
After you install Snow Leopard you will have to download and install the Mac OS X 10.6.8 Update Combo v1.1 to update Snow Leopard to 10.6.8 and give you access to the App Store. Access to the App Store enables you to download Mountain Lion if your computer meets the requirements.
Upgrading to Lion
If your computer does not meet the requirements to install Mountain Lion, it may still meet the requirements to install Lion.
You can purchase Lion by contacting Customer Service: Contacting Apple for support and service - this includes international calling numbers. The cost is $19.99 (as it was before) plus tax. It's a download. You will get an email containing a redemption code that you then use at the Mac App Store to download Lion. Save a copy of that installer to your Downloads folder because the installer deletes itself at the end of the installation.
     Lion System Requirements
       1. Mac computer with an Intel Core 2 Duo, Core i3, Core i5, Core i7,
           or Xeon processor
       2. 2GB of memory
       3. OS X v10.6.6 or later (v10.6.8 recommended)
       4. 7GB of available space
       5. Some features require an Apple ID; terms apply.

I backed up my entire hard-drive of my macbook pro - just prior to installing osx mountain lion.
I put everything into a folder on my desktop - then backed it up onto an external drive. Once this was done - i deleted the folder off my desktop - and following this - things started to go all weird...pages hanging, the coloured 'wheel of death' appeared for ages. So i had to employ a 'hard-boot' restart - as i had not other options.
I'm pretty sure i made copies of of files/apps/folders etc - however not so sure now as i cant even start up my laptop!!!
Can somebosy please help me urgently??!!!

Got the exact same problem, and I also did this operation many times before, from 500Gb to 750Gb, and then from 750Gb to 1 Gb. Not My HD got a little such complaining about bad sectors when in windows bootcamp, but still runs fine though.
So I bought a new 1Gb drive exactly same drive as the one thats getting sick. I did the clone thing, with super duper, CCC, DU, but no matter it will not boot when i move the new drive inside the macbook…….**** thing exuse me, but wasted so much time.
Now I get this strange feeling that something must have changed in the macbook itself. Just wondering if this could be a EFI "mac bios" prevention thing, they made just to sell more new computers, when you can't improve or fix your old one.
If so, then its pretty scary. If not then I simply can't figure out why this suddenly becomes a problem for so many people, as I see so many posts about this!!

Cisco Connect does not run with Mac OSX Mountain Lion (10.8.2)

When I first installed Cisco Connect that came with my E1500 router, I was running Mac OSX Snow Leopard (10.7) and it worked fine. I upgraded my OSX to Mountain Lion and now when I start Cisco Connect, I get:
Unsupported operating system
The router software supports these operating systems:
- Mac OS X 10.5.8 or later
- Mac OS X 10.6.1 or later
- Mac OS X 10.7 or later
I saw some other thread/info/download on Cisco Connect with Lion (10.7) but nothing for Moutain Lion (10.8) - is there a fix forthcoming?
Thanks
Gary

All i want to do is disable the guest function through cisco. i live in an apartment and everyone logs into my guest account. i was at my neighbours and they were laughing saying they done need to subscribe for the internet cause they just log onto local wi fi. and mine is one of them. i dont know if that'll slow down my internet with so many people using it. but all i want to do is just avoid it all together and get rid of it. but in this case i am having the same problem as all of you. to disable the guest function you need to go through cisco connect and it is not compatible with mac osx mountain lion. grrrrrrr
