OSX Mountain Lion install / download issue. Help Please!

I have attempted to download OSX ML 3 times now, each time the download completes, install runs then after restart there is no change. ML hasn't been installed. Anyone had the same issue? Any fix?

The next time you download Mountain Lion, make a copy and move it out of your Applications folder. That will save downloading it again.
What version of the OS are you currently running? If it is 10.7 try the below:
https://discussions.apple.com/message/21111661#21111661
If you look in your Applications Folder is the installer still there?
If you hold down the option/alt ket during a restart, do you see a recovery volume?
Are you getting any error messages?
Try booting into the Safe Mode to install it.
Shut down the computer and then power it back up. Immediately after hearing the startup chime, hold down the shift key and continue to hold it until the gray Apple icon and a progress bar appear. The boot up is significantly slower than normal. This will reset some caches, forces a directory check, and disables all startup and login items, among other things. If the system operates normally, there may be 3rd party applications which are causing a problem. Try deleting/disabling the third party applications after a restart. For each disable/delete, you will need to restart if you don't do them all at once.

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.)

I buy an osx mountain lion, and downloaded, but this still appear in my icon of actuazliza

i have a macbook air with os X, i buy an upgrade of OS X MOUNTAIN LION, but this still appear in my
updates list, the question is if this is working or not.....

Since you're having issues in multiple accounts I suggest you repair the HD and re-install the OS. ML makes the process pretty painless.
Boot up holding command-r keys into your Recovery Volume.
The screen should give you these choices...
Restore from TM backup
Reinstall Mac OS X
Get help online
Disk Utility
First choose DIsk Utility and run Repair Disk. If you find errors run it until all errors are fixed or it reports "Disk cannot be repaired".
Then, choose Reinstall OS X. This will be an install in place and won't affect any of your own data.

Have osx 10.6.8 running but when I go to download OSx Mountain Lion my download always fails at 142 mb, what is the problem?

Pretty much I am baffled, have OS X 10.6.8 and iMac 10.1 and internet running, plenty of available space, and 4gb ram but I cannot download Mountain lion successfully, everytime I go to download it the download stops at 142 mb, then spaz's out says its going to take 6, 8, 100, 1000 days to download then in red writing "an error has occured" shows up next to my download and I cant resume or anything.
Help me out as this is a problem on not 1 but all 4 of the iMacs at my work and I have been charged with getting them up to date for Logic X... Help an intern out haha
Thank you in advance!

Welcome to Apple Support Communities
Are all of them connected to the same network? If not, contact with the App Store support > http://www.apple.com/support/mac/app-store/contact
If they are connected to the same router, connect them to another network. Sometimes, some networks don't allow this type of downloads and they just stopped suddenly

OSX Mountain Lion Install Failed

Trying to update from 10.7.5 MacBook Air. Would tell you the version but cant due to install failier, Its the one just pre Thunderbolt.
Keeps coming up with 'The installer encounted an error that caused the istallation to fail. Contact the software manufacturer for assistance. Restart & try again etc'
Have restated & tried again no luck.
OSX Installer Version 401 (419.1)
Have check Disk Verfications & Permisions.
Any ideas?
Thanks

Sure, guess it points to that. Will try the App Forum.
Would it be worth Restoring form TM then deleting OSX MLion App & re downloading?
Thanks for you help.

I have 2012 Macbook Air with OSX mountain lion installed, but I can't find the installer

When i check on the Mac App Store, i still have to pay?
I mean it doesn't make any sense, I buy this macbook pro along with the os, and I still have to pay the OS again?
I wish they keep the CD installer just like couple years ago.
Thanks

OSX Mountain Lion "Install Fails"

Mac Mini Late 2009 [other info: mac osx sits on origional Apple supplied hard disk. Superdrive DVD is now usb attached in its own enclosure. Its slit insude the mac mini is used by a second 1TB hard disk that holds all my data. RAM = 8GB]
I downloaded OSX ML last night & kicked off the install. Checked this morning and the install failed. No meaningful error messages just a "Restart" button. When I hit Restart OSX starts to try and install OSX ML again. This has happened 4 times. Each time the install fails with 14 minutes to go. Having become board with that process the last time around I checked out the options on the Utility menu and selected Restore From Backup. Guess what!? OSX ML tries to install again. I am stumped!!! Has anyone any ideas that I can try?

go to disk utility and try to repair and verify your boot drive's disk and permissions. try reinstalling.
if that didn't work
go to where the installer is, right click it and choose "Show Package Contents"
find the installESD.dmg file and run it after you close all other applications. this should run an installer without going to the fabric background with the progress bar.
This may work for you if all else fails.

Mountain Lion install results in blank gray screen.

I recently downloaded and installed Mountain Lion on my wife's late-2007 iMac. Unfortunately, each time, after the installer finishes and reboots, the computer sticks at a blank gray screen where normally the Apple logo would appear while things boot in the background. I have tried restoring from Time Capsule and re-downloading then reinstalling, but it produces the same result.
With the gray screen problem present, I've tried a Safe Boot, holding down Option to select a disk to boot from (nothing comes up when I do this, just the mouse cursor), and resetting the PRAM/NVRAM. I haven't really been able to find anyone else having this particular issue. The hard drive in the iMac is a little over a year old as we had to replace the old one. And from what my wife read, the late-2007 iMacs are Mountain Lion compatible.

saw this in another thread about a macbook pro slowing up after OSX Mountain Lion install:
the mac owner had mentioned his mac going very slow, and was told it could take several days for the new OSX to sort things out. Perhaps this explains my issue and perhaps yours.
"Yes this can be the case, even slow shutdowns and startups. But Hardisk space can also be a factor. Anything below the 10Gig mark of space left can cause extreme slowdowns."

Where can I find a list of compatible videocameras for OSX Mountain Lion?

I need a list of compatible videocameras I can use with my Mac OSX Mountain Lion. Can someone help me? I have always used a Canon ZR 950, but I was told it would not work with this new iMac. Is there an adaptor that would work with it? I bought a Thunderbolt, but it would not connect it.

You may have a hard time finding a list of Mountain Lion compatible video cameras as it can depend on which video editing software you're using.
if you want to use iMovie for editing read here > Apple - iLife '11 Help - iMovie '11 Supported Cameras

i guess you could put the aiport utility app on your iphone, click on the aiport express there, it will show you how many devices are connected to it and the mac addresses of those devices.

I just purchased a MacBook Pro Retina. Checked my OSX and it is version 10.8.1... trying to find a way to upgrade to a higher version. In the app store it doesnt show the update nor downloading the new Mountain Lion OXS doesnt work. Please help

hienn,
Not yet. There was an upgrade page to 10.8.2 for the late 2012 models but it's down now. I have to assume that Apple pulled it because of some bugs. I would look for something next week, more likely than not. In the meantime, the OP should be good with 10.8.1 until the update shows up again.

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.

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

Can somebody please advise urgently... 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

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!!
