Need help reinstalling Mountain Lion

I was trying to reset my MacBook Air to its factory settings. I was following a YouTube video and I got as far as erasing something. Then I went to reinstall Mountain Lion and it told me my itunes account didn't have Mountain Lion purchased (I bought it from someone a month ago). SO I purchased it and have the PDF with the code. However, I cannot access the Mac App Store to redeem the code. What do I do now? My MBA is stuck in the utilities mode.!

If it is a late 2010, it probably came with Snow Leopard installed, which means you will have to have the install DVD that came with the machine. There is a retail version of Snow Leopard available from the Apple on-line store for $20, but that is version 10.6.3. The 2010 machines came with 10.6.6 and will not install from the retail DVD. If you do not have the original install disk, you can call Apple Customer Service and they will send you a disk for a fee of something like $20, you need the machine serial number to get the correct installer version.
Once you have that disk you can install the 10.6.6 version from the disk and then go to Software Update to on-line update to 10.6.8. From there, you an go to Mountain Lion or Mavericks if your model meets the specs in http://support.apple.com/kb/HT5842

I need to reinstall Mountain Lion from a Time Machine backup, but it says that the last backup is 6 months old

Hi, I need to reinstall Mountain Lion on my MacBook Pro, so I made a backup yesterday and today I tried to reinstall everything from that backup.
To my surprise, Time Machine says that the last full backup was made on February!
I've always made regular backups during these months on my Time Machine HD, what can I do to reinstall everything from the backup I made yesterday?
Thank you very much.

Most likely, some folders were inadvertently excluded from your backups, and as a result you can't restore your data in Recovery, Setup Assistant, or Migration Assistant.
Starting from a fresh installation of OS X, set up a new administrator account and log in. Follow the instructions on this page to associate your existing backups with the new installation.
You should now be able to enter Time Machine and restore your user data from a snapshot.* I suggest you do this in two stages. Quit all applications except the Finder before you begin.
Restore all the visible items at the top level of your home folder.
Hold down the option key and select Go ▹ Library from the Finder menu bar. Enter Time Machine and restore all items in the Library folder. Log out and log back in as soon as the restore is complete.
Any other invisible folders or files at the top level of your home folder that you want to preserve will have to be restored separately. For most users, that isn't necessary.
You'll have to reinstall all third-party applications from scratch, or restore them from another kind of backup, if you have one.
*If you don't see any snapshots in Time Machine, exit the time-travel view and then hold down the option key while selecting
Browse Other Backup Disks...
from the Time Machine menu, which has an icon that looks like a clock running backwards. Select the backups of your computer by its previous name. If you don't have the Time Machine menu, open the Time Machine preference pane in System Preferences and check the box marked
Show Time Machine in menu bar

Need to reinstall mountain lion from snow leopard

i was using mountain lion before my hard drive went bad and had to replace it. however, snow leopard is the only OS disc i have so that's what i used to reboot the computer once i replaced it. how do i now reinstall mountain lion back to this computer? thanks.

i updated the snow leopard so i now have the app store but when i go to purchases and hit "download" on my previous mountain lion purchase it doesn't do anything and when i click on the application name it says "The item you've requested is not currently available in the U.S. store."?? and yes, this is the same store i bought it from.

Need help with Mountain Lion downgrade to Snow Leopard

Recently upgraded to Mountain Lion, my daily applications do not work and i am losing patience, I need help downgrading to snow leopard, i have the snow leopard CDS that came with my mac
***detailed instructions help***
my mac specs
macbook pro 13" early 2011
My time machine
i have a backup with mountain lion, and i also have a backup from snow leopard,(my goal is to restore my latest backup from mountain lion to snow leopard)
i have backed up my files using time machine AND justcloud
My question is how, i do not want to lose any data, also is there any thing i need to be aware during this process

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 3.4.1.
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.

Just bought used MBP, need help registering Mountain Lion

Hi guys, I'm very new to the Apple community. I recently bought a used Macbook Pro (October 2011) on eBay, the seller tells me that in order to actually use this computer, I need an Apple ID and have bought/downloaded Mountain Lion.
I want to get this all sorted out before I recieve my MBP in the mail. Here's my problem, I have obviously made an Apple ID, however I can't seem to buy and download Mountain Lion on this site......I'm using a PC laptop currently. I don't have access to any other Mac computer to buy a copy of Mountain Lion (if that even is the correct terminology) in the meantime.
Is this whole process even necessary? What should I do?
Thanks,
Devin B

With Apple's new delivery system of the OS and the new licensing requirements to go along with it, it has become ridiculously confusing. Have the seller use Internet Recovery and do the following: boot holding down Command + Option + R to get to Disk Utility. Wipe the drive. Reinstall Mac OS - using the internet recovery will reinstall the original system (whereas using the regular recovery will reinstall the current system), so he must use the internet recovery. Shut down computer when it is either done installing, but just before the setup screen comes on. You can boot up and set it up using your own ID. Later, you can buy Mountain Lion and install it. This should work (no guarantees though - the "official" way from Apple is for the seller to contact iTunes and un-register his license in an email to them advising them that you will be buying it). That info is from a senior advisor at Apple.
With all this, remind the seller to also deauthorize the computer in iTunes.

Need help uninstalling Mountain Lion and going back to Lion.

I have just installed Mountain Lion. I am having serious compatibility issues with Matlab, though, and I want to reinstall Lion so that I can work in Matlab. I do not have a recent enough time machine backup of Lion, and I bought Lion from the app store. When I try to re-download the Lion installer from the app store, it says "You can’t upgrade this version of Mac OS X because a newer version is installed." How can I get Lion back?

Did you by chance create a USB thumb drive with the Lion Recovery HD on it? Hopefully you did. If so, you can boot from that thumb drive and you will see the Lion logo for the Reinstall Mac OS X selection on the Utilities menu.

Need Help with Mountain Lion

I just purchased my IMac on July 10th. I was told that when the new Mountain Lion operating system was announced that I did not have to pay for the new Mountain Lion within 30 days from purchase. How do I go about this. When I tried to download it says I have to pay $19.00

The date is actually July 11. Read here > Apple - See if you qualify for a free OS X Mountain Lion upgrade.
It's not from 30 days or purchase...
You may qualify for the Up-to-Date Program if you bought your Mac from Apple or an Apple Authorized Reseller on or after June 11, 2012.

Help! I need to downgrade Mountain Lion to Snow Leopard

Hello, I know this seems to be a major issue, but i'm going to try to see if someone can help.
Here's my scenario
I have an iMac i purchased in October 2010, and i have all of the original install discs, since owning the computer i've installed Lion and then Mountain Lion
I recently purchased a brand new mac, and want to sell the iMac.
I've done this a number of times (clean installs) and didn't realize this was going to be such an ordeal. I need help!
-I have all of my files off the iMac completely and on my new computer
-I've already zeroed out the hard drive
-reinstalled Mountain Lion
so there is absolutely nothing on the computer i need...
From this point
How do i get it back to Snow Leopard? and/or Do i even have to?
Thanks, please let me know if i need to clarify anything

Clean Install of Snow Leopard
     1. Boot the computer using the Snow Leopard Installer Disc. Insert the disc into the
         optical drive and restart the computer. After the chime press and hold down the
         "C" key. Release the key when you see a small spinning gear appear below the
         dark gray Apple logo.
     2. 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.
         After DU loads select the hard drive entry from the left side list (mfgr.'s ID and drive
         size.) Click on the Partition tab in the DU main window. Set the number of
         partitions to one (1) from the Partitions drop down menu, set the format type to Mac
         OS Extended (Journaled, if supported), then click on the Partition button.
     3. When the formatting has completed quit DU and return to the installer. Proceed
         with the OS X installation and follow the directions included with the installer.
     4. When the installation has completed your computer will Restart into the Setup
         Assistant. Be sure you configure your initial admin account with the exact same
         username and password that you used on your old drive. After you finish Setup
         Assistant will complete the installation after which you will be running a fresh
         install of OS X. You can now begin the update process by opening Software
         Update and installing all recommended updates to bring your installation current.

My iMac goes to disc utilities on startup, repair disk doesn't cure it and I can't reinstall Mountain Lion because I don't remember my I'd and password at the time I bought the software. Currently working abroad and at a loss can anyone help please?

My iMac goes to disc utilities on startup, repair disk doesn't cure it and I can't reinstall Mountain Lion because I don't remember my ID and password at the time I bought the software the system isn't accepting my current details and Apple isn't recognising the answers to my security questions. They don't even seem to have my correc date of birth so I can't progress the reinstallation. I'm currently abroad and have my iMac with me but with no way of contacting Apple that I can find, I'm at a loss and very reluctant to pay £35 to try and get my ID and pasword sorted out given that their system recognises my current details. can anyone help please?
AG

when they gifted me the mountain Lion software several years ago.
Mountain Lion was introduced in July 2012. Did the people who gifted you possibly use their Apple ID for the purchase of your OS? If you used your own Apple ID, you should have simply used the one you use for all things app store. The problem with any purchase at the app store is: whatever Apple ID was used to purchase, it willl stay tied to that Apple ID forever. And, purchases from the app store are not transferable.
So, you can check with the person(s) who gifted you or spend $20 to buy it - or, if your hardware is compatible with the new OS Mavericks, you could download it and associate it with your Apple ID.
FWIW, according to the licensing agreement, the OS remains the property of Apple and you are only granted a license to run it.

If you can download the ML installer you can make a bootable install media by using:
http://liondiskmaker.com/
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.
