Erase HD and Install Mountain Lion?

I have a MacBook Pro that we hardly used in our business that I want to sell and need to erase the HD and reinstall Mountain Lion. It currently has Maverick.
What would be the best way to do this?
Thanks.

Thanks for all your help.
Yes, you can use the InstallESD.dmg file from that and create a bootable USB thumb drive which you can boot from and install ML from that thumb drive.
Do you know how to extract the InstallESD.dmg file from that and use Disk Utility to Restore it to a USB thumb drive? You should be able to from within Mavericks.
Or you might be able to download DiskMaker X 3.0.3 and use that app along with an 8GB USB thumb drive to create your ML installer drive. You would point DiskMaker X to your OS X Mountain Lion.app file and follow the prompts.

Want to erase HD and install Mountain Lion

I have a mid-2009 macbook pro with osx lion. I just downloaded mountain lion and made a boot disk. I'd like to erase HD and install Mountain lion. I wanted to test the boot disk before proceeding, so I put it in, restarted holding "option". The options of selecting the HD, Recovery Drive, or the Boot Disk were presented. I selected the boot disk and nothing happens. I get the pale screen with progress circle in the middle and it goes on and on forever. However when I'm on the desktop, the boot disk opens just fine, and I can install from there. Can anyone help me troubleshoot this? I'd like to erase the HD but I'm afraid the boot disk won't load if I do, and I won't be able to install mountain lion (or anything for that matter).

I have bought a new imac late 2012 and I want to wipe clean my 2008 mac and install Mountain Lion on the old computer for my kids to have.
What do I need to do?

Boot your Mac from the System Install DVD that came with it, and erase the HD using Disk Utility. Then, reinstall the OS from the disc. Give the disc to your kids since it must always accompany the Mac it came with.
After the OS installation is complete and the Mac restarts to begin its new owner setup procedure, just shut down the Mac. Your kids can take it from there.
If you purchased Lion or Mountain Lion from the App Store, you cannot transfer it. The Apple ID you used to purchase it is required to maintain and / or reinstall the OS. Unless you want to supply your own Apple ID to your children for their use, they must purchase their own copy of Mountain Lion using their own Apple ID.
If they do not already have an Apple ID and you want them to have Mountain Lion, you will need to create one on their behalf. This does not change the above procedure - just give them the Apple ID and password you create in addition to the Mac and its discs.

I had iLife pre-installed on my aluminium Macbook 2009 with OSX Leopard on it. My hard drive broke but got most of the info off it and just installed snow Leopard on to a new drive and then downloaded and installed Mountain Lion over it. Now I don't have

I had iLife pre-installed on my aluminium Macbook 2009 with OSX Leopard on it. My hard drive broke but got most of the info off it and just installed snow Leopard on to a new drive and then downloaded and installed Mountain Lion over it. Now I don't have iLife anymore. How do I get it back?

Welcome to Apple Support Communities
Mac OS X doesn't come with iLife applications, so you have to install them manually after installing Mac OS X.
Insert the Applications disc or Mac OS X Install Disc 2 DVD and install iLfe applications. Then, open  > Software Update, and install the latest update. If you want, you can purchase iMovie, GarageBand and iPhoto in the App Store, so you will get the most recent version

I just bought and installed mountain lion, and I can't get to sign in to hotmail.Can I get some help please. Thanks.

I just bought and installed mountain lion, and I can't get to sign in to hotmail after several trials. I need help please. Thanks.

so its in a forum, which I didn't stumble upon because it wasn't anywhere in the adobe troubleshooting steps for Windows 8 that automatically came up for me when I clicked that I couldn't see the test flash movie on their site. I guess if I spent another half a day googling I might have found it.
BTW, unchecking Active X filtering in IE10, was NOT the fix. I had to go into the security tab, and change the custom active X setting I listed above. So this link you provided which mentions unchecking Active X filtering was not the fix that worked in my scenario.

I just downloaded and installed mountain lion on my macbook pro but it didn't change the picture on desktop to mountain lion in is still snow leopard is that supposed to be that way.

I just downloaded and installed mountain lion but it kept snow leopard on my screen is that supposed to happen or did i miss something?

Then you're good to go. Updating your OS doesnt change your desktop background, you can do that manually, if you wish.

I bought macbook pro and update my osx, i already have the codes and install mountain lion and its been 2 days now and still downloading mode

Disable anti virus software.
Apps such as Little Snitch, Net Nanny, and Hands Off can prevent apps from downloading including Mountain Lion as well as third party download managers.
Keep in mind, for downloading Mountain Lion from the App Store, a high speed (broadband) internet connection is strongly recommended by Apple as noted here > iTUNES STORE - MAC APP STORE - TERMS AND CONDITIONS
If you need to reinstall OS X or repair the the startup disk using Mountain Lion Recovery, that requires broadband access to the internet via Wi-Fi or an Ethernet connection. OS X is downloaded over the internet form Apple when OS X Recovery is used for reinstallation.

HT5381 "first download and install Mountain Lion"?

The upgrade/migration guide says to "first download and install Mountain Lion". Am I correct in assuming they just haven't updated it to say "Mavericks"?
Thanks,
Jascha

Which MBP do you have? Have you looked at the list of support machines on the Tech Specs page linked to http://www.apple.com/osx to see that your computer is there?

Do i need to buy the disk for mountain lion or can i just download it? if someone has a link to something helpful i would love to have it.. Thanks

If you can't run Mavericks, you can't run Mountain Lion because they have the same hardware requirements.

Downloading and Installing Mountain Lion on a 2010 Macbook Pro Running OS X 10.6.8

I'm attempting to download mountain lion, but everytime I click the download button, it turns white and the just reverts back to normal. I tried restarting the computer, and I see the dock icon saying it's downloading, but again, nothing in the App Store changes. I've tried deleting the cache for the App Store, I've tried resetting the App Store, I tried creating a VPN network, but nothing worked. I'm out of idea.

You're sure your Mac can run Mountain Lion? >>> System requirements for OS X Mountain Lion

I have a 2011 MacBook Pro and installed Mountain Lion recently and I want to uninstall it to my old software how do I do that?

Please help me out I really don't like the Mountain Lion software, the old one i had was much better and I can't seem to figure out how to get back to the one I use to have.

if you plan on doing an internet recovery install of your old os which is Lion - keep in mind that everything will be erased in your hard drive. your files are gone - unless you have made copies of them in another drive.
you will have to reinstall everything over again. if you're prepared to do that, then click on the link below to learn on how to start internet recovery since booting through your recovery partition will reinstall Mountaln Lion.
Force Lion to Start Internet Recovery.
Now, if you have a early 2011 Macbook Pro - then it came with Snow Leopard - use your install disk to reinstall.

When trying to update and install Mountain Lion's 10.8.3 update from 10.8.2, the App Store will restart my computer but not install the update. Any ideas on how to update my Macbook Pro 15" from 2008?

I was wondering, does anyone have an idea on how to update my Macbook Pro 15" to Mountain Lion's 10.8.3 from Mountain Lion's 10.8.2 version? When I attempt to use the App Store, it will restart my computer but it will not install the update. The update also still shows up in the App Store as available and when going to "About my Mac," it still shows the current version being 10.8.2.
Computer:
Macbook Pro 15" Aluminum Body
Purchased Late 2008
Current OS: Mountain Lion 10.8.2
Original OS: Leopard

I will be attempting this fix this fix tonight:

App Store doesn't know I already purchased, downloaded and installed Mountain Lion

I've have downloaded OS 10.8 Mountain Lion from the App Store on my iMac. It's downloaded and installed, but every time I open the App Store, and look at my purchases it still says I still have to download Mountain Lion. It's a small problem, but rather annoying. It there anyway for the App Store to know Mountain Lion is installed on the iMac?

No it is NOT telling you you HAVE to redownload it. It is giving you the opportunity to Re-Download it.
