How can I reinstall a MacOSX clean installation?

Hi, I need to restore Mac OSX in my Macbook Air 13'' (mid 2012) to factory settings (clean). The laptop came with Lion pre-installed, but then I upgraded to Mountain Lion (10.8) and later to 10.8.2 with patches.
I've been reading around and tried the following options:
(1) Installing Mountain Lion from USB:
I created a bootable USB (16GB) with an InstallESD.dmg image of Mountain Lion, but after restarting the laptop with the "Option" key hold and selecting the "Mac OSX" icon from the boot menu, I'm getting a prohibited icon and an eternal spinner.
(2) "Reinstall OSX" option:
After restarting with the "Option" (or "Command"+R), selecting the "Recovery 10.8.2" icon from the boot menu and then selecting the "Reinstall OSX" option from the list, it connects to the Internet to "download" and after a while I get exactly the same setup I got... No clean installation as I guessed.
Is there any way to get a fresh copy of OSX (preferably installed from USB) in the laptop? Possibly by getting an specific InstallESD.dmg version I can install...
Thanks a lot.

A "clean" installation is not possible unless you first erase the target volume.
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.

How can I reinstall Iphoto if the installation is aborted?

I just bought Iphoto 9.2.1 from Apple store and I installed it on my Mac OS X 10.6.8. When I launch Iphoto I receive the following error message:
Dyld Error Message:
Library not loaded: /Library/Frameworks/NyxAudioAnalysis.framework/Versions/A/NyxAudioAnalysis
Referenced from: /Applications/iPhoto.app/Contents/Frameworks/iLifeSlideshow.framework/Versions/ A/Frameworks/iLifeSlideshowProducer.framework/Versions/A/iLifeSlideshowProducer
Reason: image not found
It's possible that the electric power went down during the installation but I'm not sure that it happened during the installation.
Can I download and reinstall in some way the application from Apple Store?
Thank you

Yes.
To re-install iPhoto
1. Put the iPhoto.app in the trash (Drag it from your Applications Folder to the trash)
2a: On 10.5: Go to HD/Library/Receipts and remove any pkg file there with iPhoto in the name.
2b: On 10.6: Those receipts may be found as follows: In the Finder use the Go menu and select Go To Folder. In the resulting window type
/var/db/receipts/
2c: on 10.7 they're at
/private/var/db/receipts
A Finder Window will open at that location and you can remove the iPhoto pkg files.
3. Re-install.
If you purchased an iLife Disk, then iPhoto is on it.
If iPhoto was installed on your Mac when you go it then it’s on the System Restore disks that came with your Mac. Insert the first one and opt to ‘Install Bundled Applications Only.
If you purchased it on the App Store you can find it in your Purchases List.

The office suite shows up twice on the bottom--I need to uninstall and reinstall it but now it still shows up twice; documents act funky and load again when I pick the other icon--how can I reinstall completely so just one office suite in indeed installe

I put office for MAC on my macbook air--it somehow shows up twice and documents load out there depending on which one you pick. I need to get all of the office installiations off and reinstall but it appears to leave one out there. When I go to applications I cannot see it but I can see it on the icon line on the bottom of the screen. How can I reinstall Office for Mac so there is only one installation on my computer ?

Unfortunately the information given to you by r8er is incorrect, deleting the Office folder from Applications only partially uninstalls Office.
Here are the correct uninstallation instructions for you.
And the icons at the bottom are just shortcuts.

Hi,
you could try the following:
Find the file named tux.env under your installation directory (a k a TUXDIR), it may be named /opt/tuxedo or something like that.
Execute that environment setup:
. /path/to/tuxedo/tux.env
Ask Tuxedo what version it is:
tmadmin -v
Your answer will look somewhat like this:
user@host> tmadmin -v
INFO: Oracle Tuxedo, Version 10.3.0.0, 64-bit, Patch Level 119
which will inform you of the Tuxedo version, word size and (possibly) patches installed.
Hope this helps,

you can download the mac os x recovery hd and run the setup to a flash drive using another mac computer running os x 10.7,(so that while installation the os x setup can varify your computer's serial no. and provide you the installation setup through internet)
or the time machine backup(if you have)

You are allowed to have two machines with activated installations, so if you only had one installation, you still have the option to install on a second without doing anything further than that. If you originally downloaded the purchase thru Adobe then you might find a download link available in your Adobe account online. You can also download thru the following page if you can find your version:
Download and Installation Help -
https://helpx.adobe.com/download-install.html
You can have the first installation deactivated to free up the activation and have it available for another machine again as well. YOu need to contact Adobe Support thru chat for that. For the link below click the Still Need Help? option in the blue area at the bottom and choose the chat option...

How Can you reinstall Photoshop Elements12 to a computer that its was there but loss it after installing windows 8.1

How Can you reinstall Photoshop Elements12 to a computer that its was there but loss it after installing windows 8.1

Reinstalling Mavericks depends on several factors:
if you erased your recovery partition
what OS originally came on your Mac.
I'll assume you don't have a backup available that you made before your mishap, because you didn't mention it.
That's really the take home message here: have a backup!
If you still have your recovery partition:
boot into the recovery partition (command R at restart)
use the recovery partition to reinstall Mavericks. see: OS X: About OS X Recovery
if you do not still have your recovery partition, then it depends on whether your Mac originally came with installer disks or not.
If it originally came with installer disks, you would boot from the installer disks, erase your HD, and then reinstall the OS that is on the installer disks, and then upgrade as necessary until you get to Mavericks.
If your mac did not originally come with installer disks, but you managed to erase your recovery partition, then you can try to boot into internet recovery (option-command-R at restart), and use internet recovery to erase your HD and reinstall the OS that originally came with your computer, and then upgrade to Mavericks if you need to. See: Hands on with Mountain Lion's OS X Recovery and Internet Recovery | Macworld
(the reference refers to ML but it applies just as well to Mavericks).

HT1544 how can I reinstall the Mac OS X from scratch?

I have an early 2008 iMac that came with Mac OS X 10.5 leopard. I have bought all os's since then, and Today I am using the most recent one, mountain lion. My question is, how can I reinstall the Mac OS X from scratch? Is there a quick way ? Or do I have to:
Find the leopard CDs that came with the iMac
And go through the cd installation.
Then, can I jump from leopard to mountain lion?

If your goal is to just reinstall Mountain Lion, you can restart the computer holding the Command and R keys, then choose the reinstall OS X option from the utilities choices presented to you.
That restarts the computer using the recovery hard drive that was created when you installed Mountain Lion...but note you must have an internet connection when you do this reinstall.

You'll need your OS installer disk or a retail disk with a version later than the one that came with your MBP. You realize that what you want to do will necessitate erasing your HD so you might want to wait till you get back home.

       2. 1GB of memory
       3. 5GB of available disk space

How can I reinstall "Most Visited", and can I edit its features?
Thank you.

How can I reinstall Safari 8.0 without disturbing anything else?

How can I reinstall Safari 8.0 without disturbing anything else? I have OS X 10.10.1 Yosemite & Safari 8.0 (that comes in it) installed on a MacBook Pro laptop and a Mac Mini tabletop computer. I want to access internet banking which goes without problems on the laptop but does not work on the tabletop. The latter says "somebody tried to display the application in a frame..." whatever that means and obviously for safety reasons I can not start banking it always comes back to the screen with this warning. I tried Mozilla FireFox on the tabletop Mini and everything works fine including the banking. A Mac expert suggested something is wrong with the Safari settings and I should reinstall it. How do I do this without reinstalling the System? Would it suffice to wipe out the Safari Preferences and start anew? I am looking for somebody's advice more experienced than I am. Thanks!
Andy

Hello isza41,
Before you try to do any uninstall/install stuff let me suggest you something:
Create a new user and check if the same happens within its account. You could do so by going trough the following steps:
Choose Apple menu > System Preferences, then click Users & Groups.
Click the lock icon to unlock it, then enter an administrator name and password.
Click Add below the list of users.
Click the New Account pop-up menu, then choose a type of user. - Standard user account would be perfect here.
Enter a full name for the new user. An account name is generated automatically. To use a different account name, enter it now—you can’t change it later.
Enter a password for the user, then enter it again to verify. Using a password hint is recommended to help the user remember his or her password.
Click Create User.
Now Logout from your account (⌘⇧Q) and Login to the one you have just created. This account is fresh without any changed settings(as a new instance would look like).
Check if the same would happen and you would see if this is an issue with your installation or something more general.

How can I reinstall Snow Leopard?

How can I reinstall Snow Leopard?

Jan,
You can use the Disk Utility "app" to partition your hard drive so that you can (clean) install Snow Leopard on the new partition. This leaves Mountain Lion intact on one partition. This worked great for me. I was becoming increasingly annoyed, seeing that Mountain Lion ***** due, as another poster said, to its "increasing iOSification".
With Disk Utility you can name the new partition "Macintosh HD 2". Be sure to use the exact same format as the original (Macintosh HD) partition. You can access all your files/apps on the old (ML) partition from the new (SL) partition, and vice versa.
However, know this:
I still have NOT found a way to transfer any my OS X Mail folders from Mountain Lion BACK TO Snow Leopard. Mountain Lion's Mail gives you the false impression you can export your Mail folders to Snow Leopard's Mail, but you cannot. From what I've read here, the newest version of OS X Mail is not compatible with earlier versions. This is a HUGE problem.
My short list (to date) of crappy Mountain Lion behavior; items marked with a double asterisk (**)represent the worst of Mountain Lion for me.
** No up/down arrows in scroll bar slider;
Expose` not as easy to navigate as in Snow Leopard;
Mail does not request passwords for either receive or send;
No "Save Draft" icon in Mail compose window;
"Save As" selection missing in most app menus;
No separate Search window in Safari (workaround: use Firefox or Opera);
** Can't export Mail from Mountain Lion into Snow Leopard if downgrading;
iWork 09 seems to have "circled the wagons" re compatibility with MS Office or LibreOffice (workaround: just use Libreoffice);
I truly regret "upgrading" to Apple's "Vista".
