Wiping Hard Drive and Reinstalling Mountain Lion?
So I have a lot of, to be quite frank, crap on my MacBook. It's the 128GB model, meaning I can't have too much stuff on it. This used to be my only computer but over the summer I built a new one that has a whole TB+ of space on it so I've been wanting to wipe my MacBook clean. I have one issue - how do I get OS X back on here? There isn't anything on it that I'd like to save. I've tried the OS X Recovery application but it was installing OS X Lion on my little USB drive. I'm using OS X Mountain Lion though and I don't want to downgrade then have to purchase Mountain Lion even though it came pre-installed. So I'm basically asking:
1) Are there any other methods of installing OS X Mountain Lion back on my clean MacBook?
2) How exactly do I go about wiping the Drive anyway?
Please explain everything in detail so I know for sure I'm not doing anything wrong. Thanks in advance!
Uhm, bump. Still need help.

After I installed Mavericks I could no longer shut my Macbook Air (mid July 2012) down, except by force quit,I was using an Apple Tv screen and Apple wireless keyboard. After that the spinning beachball kept appearing at more and more frequent intervals, even after I had wiped the drive and re-installed Mountain Lion from the Apple site. It is now almost non functional. and just three months out of warranty
Backup your data as soon as you can.
MacBook Air computers sold between June 2012 through June 2013 are known to have a high SSD failure rate and Apple is replacing them for free.
http://www.apple.com/support/macbookair-flashdrive/
You should maintain current backups. Given the known failure rate of your SSD that is especially important.

How do i wipe my hard drive and install Mountain lion
OK i wanted to install mavrick but i got my macbook pro in june of 2007 so it's to old. The command R does nothing when i reboot, and everything i find online about clearing my hard drive and getting ready to install mountain lion has that step in it. So how do i clear my hard drive so my computer is brand new like the day i bought it and also update my OS from snow leapard. 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.
Check that your computer is compatible with Mountain Lion/Mavericks.
To check the model number hold down the option/alt key, go to the Apple menu and select System Information.
MacBook Pro (Mid/Late 2007 or newer) model number 3,1 or higher
Your Mac needs:
OS X v10.6.8 or OS X Lion already installed
2 GB or more of memory (More is better - 4 GB minimum seems to be the consensus)
8 GB or more of available space
If your computer isn’t compatible, you might be able to upgrade to Lion.

Check to make sure your applications are compatible. PowerPC applications are no longer supported after 10.6.

Can I wipe my hard drive without reinstalling Mountain Lion?
I'm running a digital version of Mountain Lion and my Mac is still running fine, but my hard drive is almost full. I'm an animation student, so I'm thinking of wiping it to get off all the junk that I don't really need for school, but I don't want to have to reinstall my OS. Is that possible?
On another note, my disk drive doesn't burn CDs anymore. It still plays DVDs fine, but the last time I tried to burn a CD it said it couldn't "calibrate the laser power needed" or something...Is there a way I can fix that? I think it just needs to be cleaned out...If you can't run Mavericks, you can't run Mountain Lion because they have the same hardware requirements.

I'm getting the grey screen during start up and can't boot the computer - MacBook Pro with lion.
I did a command r after doing some research but got nervous that it would automatically wipe my hard drive and reinstall OS.
I was nervous because it asked me for language for software use before any options were presented (such as repair via disk utility). It looked similar to an OS install.So I powered off....Is there a risk at command r will result in wiped HD without me actively making that choice?Repair the Hard Drive and Permissions - Mavericks, Lion/Mountain Lion
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
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 then click on the Repair Permissions button. When the process is completed, then quit DU and return to the main menu. Select Restart from the Apple menu.
Reinstall Mountain Lion or Mavericks
OS X Mavericks- Reinstall OS X
OS X Mountain Lion- Reinstall OS X
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is
three times faster than wireless. -
With Lion, How Can I Erase the Hard Drive and Reinstall The System Software?
I plan on buying a used iMac with a Core 2 Duo so that I can run Lion. Since Lion can only be purchased at the Mac App store what if I needed to erase my hard drive and re-install the system software. How can I do this without a DVD with the OS on it like I have for Snow Leapard. I suppose that I could boot from my Snow Leapard DVD and do the erase. Then, I supposed I would be able to download Lion again from the Mac App Store without paying for it again. But, how would you erase a hard drive and reinstall the system software when purchasing a new Mac with Lion already installed and no DVD at all with the OS on it?
-- KaydellWhen someone purchases any Apple computer with a DVD Drive, they should have recieved two DVDs... One contains the Operating System (up to Snow Leopard, Lion no longer ships on DVD) and the other contains the SYSTEM SOFTWARE (i.e. iLife and iWork). To install the software, they just insert the DVD with the SYSTEM SOFTWARE into any compatible Mac and run the installer. There is no need to erase the hard drive to install SYSTEM SOFTWARE. Maybe a friend can let you borrow the SYSTEM SOFTWARE DVD. The other option is to purchase the software via the App Store.
FYI... App Store purchases are linked to the PURCHASER'S APPLE ID. So if you buy a used Mac from a friend and that Mac already has Lion installed on it,that Lion purchase is linked to YOUR FRIEND'S APPLE ID, not yours. So if you want to download Lion again, you will have to enter your FRIEND'S APPLE ID AND PASSWORD. You can always have your friend re-download Lion and make you a DVD copy. -
Can i recover photo files lost when i wiped out my hard-drive and reinstalled mac os x?
Can i recover photo files lost when i wiped out my hard-drive and reinstalled mac os x? I know that when a computer is wiped cleaned that the info is still on the hard drive, how do I access it? Can I pay someone to access it? Long story short, everything was saved to my external hard drive except my photos, by mistake of course.
You have to stop using the drive immediately. Completely stop. Do not boot the computer from the drive.
File recovery software: Try using an application such as Data Rescue 3 - http://www.prosofteng.com/products/data_rescue.php or FileSalvage - http://subrosasoft.com, or one of the ones listed in the (old) link below. Some have free trial versions that let you see if the software will help before you decide to buy. You will also need a second hard drive equal to or larger in size than your first drive as a destination drive for recovered files.
http://data-recovery-software-review.toptenreviews.com/mac-recovery-software
It is critical that you do not use the computer or even turn it on until you have rescued your files. Files only have the directory reference to them removed when you empty the trash or otherwise delete them from a computer (unless you use secure erase, in which case they are gone forever or can only be potentially be recovered by very expensive means) and are still present on the computer. However, their space is marked as available to any other file creation done on the computer (even done by you booting the computer) and there is risk that your files will be overwritten by the computer.
Even if the above works, do not expect the results to be pretty or even 100% successful. Files will often lose their names and you will have to re-name them one by one. -
My 2009 MacBook Pro keeps restarting even after I wiped the hard drive and reinstalled OSX.
About a month ago, my laptop started to randomly turn off: I would be using either Chrome, Photoshop (the free CS2 version available from Adobe's website) or Powerpoint, and the screen would go blank. I would then have to hold the power button for a while until the little light at the front of the computer would flicker and it would restart. I brought it to the Mac Store where they tested it and said it looked fine. They suggested I erase my hard drive and reinstall OSX as a precaution.
Fast forward a month, I have been very busy with work and hadn't been able to fix this problem. It wasn't that bad, only once every couple of days, sometimes more, sometimes less, I could work despite this problem.
Then, I installed OSX Mavericks. The installation started in the morning, but, like an idiot, I paused it to go to work. Later on, I completed the installation, it looked fine, but then all day long my laptop would suddenly restart and go to a grey screen that said in multiple languages "Your laptop restarted because of a problem, press any button to continue the restart." A computer technician friend of mine checked it out and said it was probably due to the badly installed OSX and suggested that I erase my hard drive and reinstall OSX.
I backed up all my files, erased the hard drive and reinstalled OSX. Everything looked fine.
Then it happened again.
Any ideas of why this is happening?Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually login 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.
Test while in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of the test. -
Can I transfer a Time Machine backup to a new empty hard drive, without installing Mountain Lion on that new hard drive?
Yes - I just did it the other night. Took five hours, but it finally finished and is working great.
I sort of followed the instructions found here -->> http://pondini.org/TM/18.html.
Also, if you want to have dual backups, see -->>
http://pondini.org/TM/27.html.
I say 'sort of' because I used Carbon Copy Cloner to do a block-level transfer. I just didn't want to get hung up with a Finder copy.
Give CCC a try - you have to enable the block copy in Preferences before using this method, but I was quite happy with it. I used it to move over 1TB of TM backups from a FireWire 800 drive to a 2TB Thunderbolt drive. 5 seconds short of taking 5 hours.
It should work well for you.

I have to reformat my hard drive and reinstall all of my programs. What do I do about Creative Cloud? I also still need access to CS6 (I have a Marksware converter for InDesign to Quark).
This is a MacBook Pro 15" (Model number A1286) running Mavericks. Hard drive is fine but system software has been corrupted. I cannot simply restore from Time Machine as it will copy the corrupt system.
Will I have to find all of my serial numbers before I can launch any of the programs?
ThanksFor the Cloud, you log in to your paid Cloud account and download & install the same way you did the first time

If you have the perpetual license version of CS6 you install from your original media and use your serial number
