Will reinstalling mountain lion fix image retention

After installing mavericks i started getting image retention so i was wondering if reinstalling mountain lion will fix my problem.

It's unlikely that has a thing to do with OS version. But it you wish to reinstall Mountain Lion:
Erase the drive.
Reinstall Mountain Lion from a backup.
Since your computer can run Mavericks you will no longer be able to re-download Mountain Lion. However, if Mountain Lion was pre-installed on your computer, then you may be able to reinstall it by going through an Internet Recovery:
Install Mavericks, Lion/Mountain Lion Using Internet Recovery
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
Boot to the Internet Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND-OPTION- R keys until a globe appears on the screen. Wait patiently - 15-20 minutes - until the Recovery main menu appears.
Partition and Format the hard drive:
Select Disk Utility from the main menu and click on the Continue button.
After DU loads select your newly installed hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed. Quit DU and return to the main menu.
Reinstall Lion/Mountain Lion. Mavericks: Select Reinstall Lion/Mountain Lion, Mavericks and click on the Install button. Be sure to select the correct drive to use if you have more than one.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
This may restore the version of OS X originally pre-installed on the computer.

First run Disk Utility Repair Disk, if you get errors run until no errors reported or reports "the disk cannot be fixed". Then, choose Reinstall OS X. This will be an install "in place" and shouldn't effect any of your own data or settings.

Will my MacbookPro still be under warranty if i format and reinstall mountain lion from scratch?

Hello everyone,
as in title, will my MacbookPro still be under warranty if i format and reinstall mountain lion from scratch? After the release of mountain lion, bought it and reinstalled it on the previous version,but the system looks slightly slower.So my thought was to format and install it from scratch.But being my computer 1 month old,will this influence my warranty?Thank you for answers.Cheers.M

Reinstall doesn't broke the warranty, so you can reinstall OS X Mountain Lion

My ex girlfriend wiped my 6yo daughters imac and will not give me the 4 digit passcode pin. How do i get past this to reinstall mountain lion ? Any help would be greatly appreciated

Could anybody offer me advice on what I can do to reinstall mountain lion on my daughters imac as my ex wiped the whole computer via find my iphone and will not give me the 4 digit passcode ? Any help and advice would be greatly appreciated..

Take it to an Apple Store, have proof of purchase with you.

How many times can you reinstall Mountain Lion?

Since I bought the Early 2013 15" MacBook Pro retina laptop used only 17 battery cycles on it now (2.7 with 16GB ram running Mt. Lion) computer I have not reset it. I spoke to Apple and it is registered in my name, I made a new Admin. account and password and Apple had me delete the original owners. I took off anything he had left on it. Applecare also I bought in my name. Apple said I didn't have to reset it and would be fine so I left it. They deauthorized the previous iunes account and the previous owner gave me his ID to deauthorize the computer. It was already deauthorized when I checked. He then changed his password for his security. It runs beautifully and has a Samsung screen.
I deleted the iLife apps and were going to buy them in my name (as his ID came up for updates) but now can't redownload in my name as it says I need Maverick OSon it to do so. I left the Mountain Lion 10.8.5 on it. If I contact Apple will they give me a redemption code for my name or how do I get older versions?
If I reset to new how many times am I able to reinstall Mountain Lion? If I decide to sell it later will I be able to reset it again with no problem for the new owner?
Thank you for your help. This forum is a source for many of us new owners to solve things.

As long as you do the download with your Apple ID, it'll be in your name. Reverting back can be a little involved. If you have that in mind, you should make a full backup of your clean install of ML and save it somewhere. Then you can just copy the image back with Carbon Copy Cloner. External drives are cheap, that's how I'd do it.

I recently purchased an iMac from a friend who factory reset it, and now I can't reinstall Mountain Lion?

     As the title says, I can't reinstall Mountain Lion. When I turn on the iMac, it send me straight to OX X Utilities. When I click on Reinstall Mountain Lion, it asks for my ID, but then states I did not purchase Mountain Lion. How do I fix this issue? I've tried asking Apple Support, but to no avail. I don't think the guy I spoke with understood what was going on.
I cannot get around OS X Utilities. There are only four options for me.
Reinstall Mountain Lion
Back Up (tried, nothing comes up)
Get Help Online (which is what I'm doing here)
Erase or Restore Utilities (I've checked this, it says my disks are not malfunctioning)
     My friend suggested signing into his ID to reinstall but when we did, it also said this ID has not purchased Mountain Lion. We logged into Apple Support went to registed devices and there was nothing there. I think he may have used another ID which is he searching for the info for. If we get the right ID, then maybe it will let us sign in on his name and reinstall Mountain Lion. But if he can't, or Apple won't take his ID, then I'm at a loss for options.
     So now I'm here, hoping someone else who bought a used iMac from a friend who factory reset it and needs info on how to reinstall Mountain Lion can help me. I don't know what else to do. If I can't get this thing sorted out, I'll have to drive to the apple store. The closest one is 60 miles away, so I'm not looking forward to that. Is that my only option now? What can I do?
tl;dr I bought a used iMac from a friend who factory reset it, and now I don't know how to reinstall Mountain Lion. What are my options?

If the system didn't ship with Mountain Lion originally and you didn't purchase Mountain Lion yourself, then you will need to purchase. A purchase by the system's original owner cannot be transferred to you.
Unless you have another system on which you have purchased Mountain Lion, you will need to first install Mac OS X 10.6.8 on the iMac, for which you'll need either the original installation disks, if the iMac came with 10.6, or a retail copy of 10.6. Install 10.6 and upgrade to at least 10.6.6, and then you can buy Mountain Lion from the Mac App Store, presuming of course that the imac can support Mountain Lion. See:
http://www.apple.com/osx/how-to-upgrade/

A few questions before proceeding to uninstall/reinstall Mountain Lion

Since I'm new to this forum I inadvertently closed the discussion that I initiated myself without it being resolved, so I'll copy what I had asked in the previous discussion over to a new thread:
23-Oct-2012 16:08 (in response to ds store)
Since yesterday I've done this:
Safe boot
smc reset
pram reset
hardware test looped 5 times off of original discs: no trouble
check battery: good condition
reinstalled flash with click for flash in Safari, updated Firefox to 16
Startup Manager: Volumes are Mac hd and recovery 10.8.1: did repair disk and permissions repair
Onyx: did everything and rebooted. There was trouble with epson permissions that was fixed and still recurred, went to users and deleted printers and then went to epson and downloaded uninstall from July 2012 and removed with that anything that was there
Still crashes though, so I thought I would do this, I'm nervous about it though:
command r boot off Recovery HD partition and Disk Utility Erase with Security Option: Zero the OS X drive/partition. Check under Partition: Options: GUID and Format: OS X Extended Journaled and apply if not already set.
Quit and install 10.6 or 107+ from Apple's servers.
Reboot, use the same user name as before (different password advised)
quit and install 10.6 or 107, what is 107? does this mean 10.8? I'm confused by that
so I must write down the user name, not the owner name, both of which I changed
I also before had created a new user and deleted my friends user accounts, so that was done already but didn't help.
when you say different password advised, you mean change that later in users?
When adobe asks for id are they asking for my id that I created to get to this forum or my user name and computer password or the computer name and password?
I'm ready to do this once I get things ironed out.....I'm afraid something awful will happen....but I guess I've done what I can for the most part otherwise.
Thank you for your help, it's been great!
23-Oct-2012 16:28 (in response to ds store)
I also did try to command r and reinstall mountain lion but when I entered my adobe id they said that it has not been used in the app store.....
so I'm not sure where that leads, whether entering my friends id and password might have lead to a free reinstall or even how to get any reinstall,
however I'm happier with the idea of a fresh restart...but worried I won''t be allowed to or run into a message like that ....or it will cost a huge amount
but you say I believe that it is quite simple and free?
23-Oct-2012 16:31 (in response to ds store)
"quit and install from apple servers"
is this something that happens within the program without rebooting? Is the "install from apple servers"given as a prompt after you select the "quit" button?
23-Oct-2012 16:42 (in response to ds store)
Do I need to download and install this?
http://support.apple.com/kb/DL1492
I have noticed that somethings have improved with all these changes, I continue to delete programs that seem outdated and unneccesary, however there still seems to be lots of crashes, and a clean install deleting everything and starting again with mountain lion is what I'd like to do once I get these final things sorted out.
Thank you

No, please don't do that. Here's how you do one or the other:
Downgrade Lion/Mountain Lion to Snow Leopard
1. Boot from your Snow Leopard Installer Disc. After the installer
      loads select your language and click on the Continue
      button. When the menu bar appears select Disk Utility from the
      Utilities menu.
2. After DU loads select your hard drive (this is the entry with the
      mfgr.'s ID and size) from the left side list. Note the SMART status
      of the drive in DU's status area. If it does not say "Verified" then
      the drive is failing or has failed and will need replacing. SMART
      info will not be reported on external drives. Otherwise, click on
      the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions
      from the drop down menu to one. Set the format type to Mac OS
      Extended (Journaled.) Click on the Options button, set the
      partition scheme to GUID then click on the OK button. Click on
      the Partition button and wait until the process has completed.
4. Quit DU and return to the installer. Install Snow Leopard.
This will erase the whole drive so be sure to backup your files if you don't have a backup already. If you have performed a TM backup using Lion be aware that you cannot restore from that backup in Snow Leopard (see below.) I suggest you make a separate backup using Carbon Copy Cloner.
If you have Snow Leopard Time Machine backups, do a full system restore per #14 in Time Machine - Frequently Asked Questions. If you have subsequent backups from Lion, you can restore newer items selectively, via the "Star Wars" display, per #15 there, but be careful; some Snow Leopard apps may not work with the Lion files.
Reinstalling Lion/Mountain Lion Without Erasing the Drive
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu.
Reinstall Lion/Mountain Lion: Select Reinstall Lion/Mountain Lion and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
Install or Reinstall Lion/Mountain Lion from Scratch
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Erase the hard drive:
1. Select Disk Utility from the main menu and click on the Continue button.
2. After DU loads select your startup volume (usually Macintosh HD) from the left side list. Click on
      the Erase tab in the DU main window.
3. Set the format type to Mac OS Extended (Journaled.) Optionally, click on the Security button and set the Zero
        Data option to one-pass. Click on the Erase button and wait until the process has completed.
4. Quit DU and return to the main menu.
Reinstall Lion: Select Reinstall Lion/Mountain Lion and click on the Install button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.

Reinstalling mountain lion after upgrading to mavericks

I am in need to downgrade my current install of Mavericks back to the original install of Mountain Lion due to compatablity issues. One of my college courses software programs crashes alot under 10.9. A fellow classmate, still runs 10.8 on their 15' rMBP without any issues. I've attempted to do a "factory restore" but on the recovery HD, the only option of the reinstall appears to be Mavericks vice Mountain Lion. To complicate matters, my last known backup under 10.8 in Time Machine was no longer there. Any suggestions or solutions, if any, are greatly appreciated. Sadly, I had to resort to using my old Windows laptop for this course until the publisher issues a fix, in which, they say is coming soon.

My Mavericks upgrade crashed my hard drive and I had to reinstall Mountain Lion. Now I cannot get any of the apps that I purchased to download. The icons on the launchpad just say "waiting" no matter what I try.

My Mavericks upgrade crashed my hard drive and I had to reinstall Mountain Lion. Now I cannot get any of the apps that I purchased to download. The icons on the launchpad just say "waiting" no matter what I try. My app store ID is fine. What do I do?

Are you now using a different username from the one you used prior to migrating? If so that is the reason for the problem. You might, then, give this a try:
To fix Home folder permissions
Open the Terminal application in the Utilities folder. At the command line prompt enter or paste the following command line:
sudo chown -R `id -un`:`id -gn` ~
Press RETURN. You will be prompted to enter your admin password which will not be echoed.

Can't restore iLife after reinstalling Mountain Lion

After I erase the internal disk and reinstall Mountain Lion, I followed this instruction which Apple provides officially to restore my iLife:
Restoring iLife applications after Internet Restore of OS X Lion or OS X Mountain Lion
If you erase install OS X Lion or OS X Mountain Lion on a new Mac that shipped with OS X Lion or OS X Mountain Lion installed, you can download iPhoto, iMovie, and GarageBand from the Mac App Store.
After installation, start (up) from OS X.
Double-click the App Store icon in the dock.
Enter your Apple ID and password.
Click Purchases.
If you haven't previously accepted your bundled iLife applications within the Mac App Store, you should see your iLife applications appear in the Accept portion of the screen. Click Accept.
You may be asked for your Apple ID and password once again. Your iLife applications now move to the Purchased section. These applications are part of the software that came with your Lion based computer. Your account will not be charged for them. Click Install to complete installation of your applications.
However, when I finish #5, I can't find my iLife apps are listed in that "Purchases" tab. Can anyone help me solve this problem?

How do I reinstall Mountain Lion in English on a system that was originally in Chinese?

I'm trying to help a friend who was given a used 13" MacBook Air (A1369) by the Chinese exchange student staying with him. It needed a screen repair, which was done, and we were able to change the display menus to English which is fine for general use. BUT... The previous owner had all kinds of Chinese games and programs as well as a partitioned HD. The plan was to just erase and reinstall Mountain Lion (which it came with, we THINK) and he'd have a fresh start.
Using the Recovery system would be great, except that since the comp was from China, and the ID associated with it is in Chinese, all of the instructions, menus and EVERYTHING are in Chinese. We can get online fine, and tried booting from a USB drive but everything is still in Chinese. We got as far as making a bootable USB and it looked like everything was OK, and started the erase/restore process but it got stuck in Chinese instructions and menus!!!
Is there a way to buy new copy of Mountain Lion with a new Apple ID that will be in English and then install it on a computer that was already running Mountain Lion? It seems I should be able to DL the OS to a USB drive and then just boot and install from that. But I'd have to DL on another Mac with its own ID running Lion. (Or use a Linux PC which seems like an even worse option.)
Any ideas? Suggestions? Laughter?

Try posting again in the forum for ML, since it hardly seems to have anything to do with your hardware.

Hard drive died... How do I reinstall Mountain Lion onto an external drive?

I have Time Machine and two extra external drives but now I cannot boot from the Hard Drive to reinstall Mountain Lion. I have a recovery partition from TechTool but it does not include Time Machine or the App Store. My computer boots into the TechTool disk but my hard drive is not shown. Disk Utility does not see my hard drive either.
Any suggestions?
TIA

Sorry, I'm confused.
The recovery partition from Tech Tool, this is on the internal HD or on a CD/DVD?
Is this the same thing as the TechTool disk that your computer can boot into?
Where is the Disk Utility that cannot see your hard drive? Is it on the Apple recovery partition on your internal drive? Are you saying that Disk Utility on your Apple recovery partition cannot see your boot partition?
It sounds like your internal boot partition won't work, but the internal drive itself is OK (i.e., Disk Utility, on your Apple recovery partition, doesn't see the normal boot partition), or at least OK to the extent that the Apple Recovery partition can run.
If you install Mountain Lion on your external drive and use it as the boot drive for your computer, it will be very slow, and you won't be happy. I'd forget that idea.
Assuming I am thinking correctly about your situation, I would try to repair your HD. Your options would be:
a safe boot Mac OS X: What is Safe Boot, Safe Mode? and then disk utility
boot into single user mode and see if you can repair your hard drive Repair Your Hard Disk in Single User Mode | Everything Macintosh
internet recovery OS X: About OS X Recovery
recovery disk assisant, if you have made one already OS X Recovery Disk Assistant v1.0
If none of that works, then I'd try and wipe the entire drive and start over. I'd try to do that from internet recovery. Hopefully one of your external drives has backups on it.
If that doesn't work, then I'd replace the drive.

How do I Reinstall Mountain Lion on a used Macbook Pro?

So I just recently purchased a 2011 Macbook Pro off of Craigslist. A friend picked it up for me, installed an extra copy of Windows 8 he had for me under my name, and made sure the OSX Mountain Lion side worked fine. Somehow, after the first time I restarted OSX it would no longer boot up, but Windows worked fine. So I booted up in the recovery partition, reformatted the OSX partition, and attempted to install Mountain Lion.
The problem is that I don't have it listed under my Apple I.D. as purchased, which makes sense because the last Macbook I bought came with Leopard. I tried to buy it on the Windows side through iTunes, but I'm not able. So my question is can I just buy Mountain Lion on someone else's Mac through the App store under my I.D., and will I then be able to reinstall Mountain Lion through the recovery partition?
Or will I have to resort to resetting my Macbook Pro to factory defaults, losing the copy of Windows 8 I was given, and reverting back to the original OS, which I'm guessing is Lion?

Well, you need to log in to the App Store on a Mac, using your AppleID, and purchase Mountain Lion. Then, on the konked out Mac's Recovery Partition you'll be able to sign in with the same AppleID and download the ML installer you are now eligible to use.

If you can download the ML installer you can make a bootable install media by using:

If your Mini came with ML you can also boot to Internet Recovery
OS X: About OS X Recovery
and it will install ML. Make sure you boot to Internet Recovery and not the Recovery Partition. If to the partition you will only get Mavericks.
