You do meet the hardware requirements. Otherwise you wouldn't have been able to purchase ML.
If you're connected wirelessly to your router, connect with Ethernet.
If you're connecting through a proxy, connect directly.
Boot in safe mode (shift key down at startup) and try again.

This copy of the Install OS X Mountain Lion application is damaged, and can't be used to install OS X.

This copy of the Install OS X Mountain Lion application is damaged, and can't be used to install OS X.

I attempted to burn a DVD of the installer, but that didn't work (files are too big).
Also grabbed the ESD from inside the package and it started to work, then hung on the "installing" screen.
Here is how I finally solved the problem after redownloading it 4-5 times:
Put my MacBook Pro into target mode and used my Mac Mini to install Mtn Lion.
At first the installer balked saying it wasn't signed right or some such BS. I tried again and it worked fine. I now even have a recovery parition which I didn't have before.
So in the end I have no idea what the problem was but it was not:
A proxy error corrupting the download
A corrupted download of any kind
Permissions errors
Hard drive errors
Incompatability with RAM or my hardware
Incompatibility of my partitioning scheme
I think there is a bug in the "pre-flight" checks the installer does prior to doing its job.

This copy of the Install OS X Mavericks application is damaged, and can't be used to install OS X.

I try to install Mavericks to my MacPro, I got this mesaage after I downloaded the OS. "This copy of the Install OS X Mavericks application is damaged, and can't be used to install OS X". I dowlaod 5 times already but still doesn't work. Anyboby know how to make it works?

This could be a problem with your router. I had replaced one if my Linksys routers with dd-wrt firmware. Overall my router ran a whole lot better but then I started noticing very large files would download only up to a certain point then they would be corrupted. The issue was only discovered by me when I was downloading iOS images.
After extensive network troubleshooting I discovered the problem appeared to be my router that was dropping the packets and causing corruption. So I replaced my firmware back to stock and my downloads worked fine.
I am not suggesting you replaced your router firmware and this is your problem but I do think it is worth a try to see what happens with a different router.

I can not update OS X mavericks, my macbook OS X lion 10.7.5, when i install that show me This copy of the Install OS X Mavericks application, my brother can upgrade with internet that just me can do that

Is your MacBook compatible with Mavericks? Open  > About this Mac > More Info, and you will see the MacBook model you have got. Then, check in this site if it's supported > http://www.apple.com/osx/specs
If your Mac is not compatible, OS X 10.7.5 is the most recent version for your Mac. Also, copy the whole message you see when you open the Mavericks installer

HT4718 My copy of Lion is damaged and can't be used for reinstallation, what can i do?

when I launch Lion Recovery and try to reinstall the OS, there is a message that says that my copy of lion is damaged and can't be used for reinstallation. what can I do?

Sorry but that makes no sense.
The Lion install files are not stored on your computer so they can't be damaged. When using the Lion Recovery HD and you want to Re-Install Lion the install files are downloaded from the internet before the actual install begins.
If at one time you saved the Lion install files, secifically the InstallESD.DMG, and created your own Lion Install USB thumb drive and that is what you are booting from then this same type of thing has happened to me.
If you can't boot to the current Lion install, or you wiped your hard drive, you can try booting to the included Recovery HD and then download and install Lion or try the Online Internet Recovery HD system by holding down the Command+r keys OR the Command+Option+r keys when starting the system. One of those keyboard combos will take you to the online Lion Recovery system where you can download and install Lion.

"Damaged and can't be opened" file error

Hi all
When I try opening a number of games on my iMac, I am getting the error message (for example COD) "Call of Duty 4 - Modern Warfare" is damaged and can't be opened. Delete "Call of Duty 4 - Modern Warfare and download it again from the App Store"
The last tme I used these apps/games (specifically Call Of Duty 4, Doom 3 and Battlefield 2012) was months ago... apart from COD4 which I definitely fired up and was working 6 weeks ago. (Don't play games much!)
I have searched for the answer, and most similar problems are associated with Gatekeeper - i.e. setting to allow install from amy location. But two of these apps are from the AppStore (I bought Battlefield elsewhere).
I have tried;-
* Deleting/Download the app again from AppStore
* Setting Gatekeeper to "Allow Applications Downloaded from anywhere" (Always had this setting)
* Running Disk Utility "Repair Disk Permissions"
* Using AppCleaner to delete all settings as well as the App (**** going to lose my place in the game!)
- Also deleting the trash. Then re-downloading/Installing.
It's really weird that none of my other Apps apart from these 3 games get the error.
I Installed COD4 on my Macbook Air which is the same OSX/Update level (latest) and it WORKS. So something is specifically wrong with my iMac
I'm wondering if there are any OSX security/java/whatever updates which could have affected this But once again it all works on my Macbook Air.
Are there any files/settings that Appcleaner misses that I could reset/delete and try again?
Perplexed...

Please read this whole message before doing anything. This procedure is a test, not a solution. Don’t be disappointed when you find that nothing has changed after you complete it. Step 1 The purpose of this step is to determine whether the problem is localized to your user account. Enable guest logins* and log in as Guest. For instructions, launch the System Preferences application, select Help from the menu bar, and enter “Set up guest users” (without the quotes) in the search box. Don't use the Safari-only “Guest User” login created by “Find My Mac.” While logged in as Guest, you won’t have access to any of your personal files or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin. Test while logged in as Guest. Same problem? After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it. *Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing. Step 2 The purpose of this step is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login. Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode* and log in to the account with the problem. The instructions provided by Apple are as follows:
Shut down your computer, wait 30 seconds, and then hold down the shift key while pressing the power button.
When you see the gray Apple logo, release the shift key.
If you are prompted to log in, type your password, and then hold down the shift key again as you click Log in.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs. The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin. *Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t boot in safe mode. Test while in safe mode. Same problem? After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of steps 1 and 2.

Error Message says Preview is damaged and can't be opened.

Whenever I try to open a file associated with Preview by double-clicking the file I get the following error message...
If I open Preview first and then open the same file from within Preview it works fine. I've tried going into Info for various filetypes and changing the "Open with:" value to change it to something else then change it back to Preview but that doesn't change the behavior. As you can see in the error message it says "Acorn created this file on August 27, 2014"... no idea what that means. I tried deleting the Acorn app but get the same error message.
Never seen this before and can't find anything specific to this behavior with Preview on these discussions or on the Web. Any suggestions would be greatly appreciated.
Cheers!

Hi MBP_Kirk ,
Welcome to the Apple Support Communities!
I know this type of alert can be concerning and frustrating. There is some troubleshooting that I would suggest when you receive an error that an app is damaged and can’t be opened, however. The first attached article explains this alert and the possible cause.
OS X: About Gatekeeper - Apple Support
"Damaged" app. – The app has been altered by something other than the developer. This message will appear no matter the Gatekeeper option chosen.
"App name" is damaged and can't be opened. You should move it to the Trash.
Safari downloaded this file on Date & Time from URL.
For troubleshooting this situation, I would first recommend simply reinstalling OS X Yosemite on your computer. Please use the instructions located in the next attached article to complete this process.
OS X Yosemite: Reinstall OS X
Best regards,
Joe

This copy of the Install OS X Mountain Lion application can't be verified. It may have been corrupted or tampered with during downloading. Dr Nir Hus

Downloaded latest OS X and installed on my Mac Book Pro (early 2008). No problems.
Then attempted to install on my Mac Mini 2011 and continuously getting the following message:
"This copy of the Install OS X Mountain Lion application can't be verified. It may have been corrupted or tampered with during downloading."
I noticed that I am not the only one...
Anyone with a solution.
So far all I see are various attempts by people, some successful others not.
This should not be a frustrating complicated ordeal!!!

Yup, the safe mode/repair/redownload/install finally solved it - had to do it after midnight as all the 4gig downloads have already trashed my 60gig internet limit for this month, installed REALLY slowly bugt eventually at 0330 i had working Mountatin Lion on my Macbook.
This has to be the most tedious upgrade, Mac OR Windows, I've ever done. Takes me back to inserting 15 floppies for sheer inconvenience, and from the numbers reporting this problem, it's more than an occasional glitch. And for some reason the download always fails if left unattended, even if all the sleep modes, etc, are negated.
3/10 to Apple this time around.

When installing mountain lion on my computer, why does it say "OSX Mountain Lion couldn't be installed, because the disk \ is damaged and can't be repaired."

I'm unable install mountain lion on my computer. Every time it says "OSX Mountain Lion couldn't be installed, because the disk \ is damaged and can't be repaired. Click restart to restart your computer and try installing again." So I press the only button listed as an option, it restarts, and the same screen comes up again. I can't make mountain lion go away...I've tried many times. What is wrong with my computer? It's stuck like this and I can't even get snow leopard back on there if I wanted to because I can't get away from the same screen. Please help : (

Insert your OS installer disk in the optical drive. Power the Mac down by holding down the power button. Then power back up and hold down the 'c' key so the MBP boots to the installer disk. From Disk Utility you should do a Repair Disk. If DU successfully repairs the disk quit the installer and reboot your Mac. You should update to 10.6.8 prior to upgrading to ML.

Then do your ML upgrade install.

I am trying to instal incloud on my macbook. Its the white computer from 2008 year. In order to do that I need to install the Mac OS Lion and ILife. I was able to buy the apps and install them on my other computer but How do I install on this computer?

Does your Mac meet the requirements?
Lion 10.7 System Requirements
    •    Mac computer with an Intel Core 2 Duo, Core i3, Core i5, Core i7, or Xeon processor (most models released since late 2006 - early Intel-based Macs with Core Solo or Core Duo processors aren't compatible)
    •    2GB of memory (recommend at least 4GB -- and ideally even more, as you'll see benefits in many computing tasks)
    •    OS X v10.6.6 or later (v10.6.8 recommended) for Lion download from Apple App Store; or Leopard 10.5.x if using Lion on USB drive
    •    7GB of available space (10GB recommended)

Make certain you have updated to the absolute latest Java from the official Java site, then try the download again.
YESTERDAY, 2 Feb 2013, new version of Java 7 was released by Oracle.
If you are running 10.7 or later get it ONLY from here, NOT from third parties:

M. Lion error: A server with the specified hostname could not be found

Hi,
I haven't been able to update apps since upgrading to Mountain Lion 10.8.1. Keep getting the error in the subject of this post.
Not even able to install the upgrade to 10.8.2 . Don't even see the option in the App Store and when I download the upgrade manually fom the Apple Support site, the installation fails saying that it can not be installed on my hard drive because I need have 10.8.2 installed !!
I saw a discussion for a similar error that recommends checking and fixing the Hosts file. I think there's an error on mine but it would not let me save it after i make a change. I've pasted the contents of my host file below to make sure that there's in fact an error on it (on the last line - looks like an IPv6 address even tough I don't use this type of address).
Thanks in advance for any help you could proovide

Hi Chris,
great news. I could not find any of the files you listed except for this one:
"/Library/Preferences/com.apple.SoftwareUpdate.plist"
After I renamed this one, my updates started working.
Thanks much for the great suggestions

Receive error: There was an error while copying to the Clipboard. An internal error occurred.

I receive the message "There was an error while copying to the Clipboard. An internal error occurred." when I highlight anything and copy to the clipboard. I've searched and found others with the same issue, but they were either on an older OS, Acrobat ver, or their issue was intermittent. My issue always occurrs and I cannot copy anything to the clipboard.
I'm running Win 7 Ultimate x64 SP1 and Acrobat Pro 9.4.4. Any suggestions would be appreciated.
Thanks,
