Installing a clean OS X Mavericks without erasing the hard drive?

Is it possible to install a "clean" OS X Mavericks (i.e. a fresh OS, NOT just upgrading over the existing OS) without erasing the hard drive? I might be dating myself here, but I recall being able to do this with previous OS upgrades. I'm currently running Mountain Lion and think maybe something has gotten corrupted. I am specifically having trouble with Time Machine. I'm hoping a fresh OS will fix it, but I'd rather not erase my hard drive. Since Time Machine isn't working, backing up and restoring the hard drive would be tedious.

Use the Disk Utility to repartition the drive, or install Mavericks onto an external one. The Archive & Install option was removed in 10.6.

1. Make a backup, open App Store and purchase Mountain Lion. When its download finishes, close the installer and open Lion Diskmaker to create a bootable USB drive with Mountain Lion.
2. Press Option key while your Mac is starting, select the external drive and open Disk Utility.
3. Select Macintosh HD in the sidebar and erase the drive.
4. Close the window and install Mountain Lion

Following having to erase the hard drive, I am attempting to re-install CS5 upgrade........

Following having to erase the hard drive, I am attempting to re-install CS5 from previously registered CDs as an upgrade to CS2. Although at the time of purchase, CS2 was acceptable, and the serial numbers of the NEW software remain registered on my 'account', the serial number of the original CS2 is now rejected as UN-acceptable, the oldest version now acceptable seeming to be CS3
What do I do????

can you select cs2 as an upgradeable option in the dropdown box after entering your cs5 serial number?
if yes, use this serial number, Error: Activation Server Unavailable | CS2, Acrobat 7, Audition 3
if not, contact adobe support by clicking here and, when available, click 'still need help', https://helpx.adobe.com/contact.html

If I upgraded my MacBook Pro from Snow Leopard to Lion via the web and now wish to erase the hard drive and restore it to factory settings to sell. How do I accomplish this?

I upgraded the operating system on my MacBook Pro from Snow Leopard to Lion via the web. Now I need to erase the hard drive and restore it to factory settings, so that I can pass it on. How do I accomplish this? When I insert the Mac OS X install disk, the only option is to erase the free space. Any insight would be appreciated.
Thank you

You need to boot off the original Snow Leopard DVD's that came with the system.
Once you are running off of the DVD you will be able to do a clean install of SL
To boot off the DVD with the system up running Lion insert the DVD. Open Sytem Preferences->Startup Disk and select the DVD then restart the machine.

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?

When 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.

Used MacBook Air 11" erased the hard drive in attempt to reinstall the OSX

Hello all,
So I have a new "used" MacBook Air 11" that I bought off Kijiji.
It came with a seemingly fresh install of OS X, but I decided to wipe out the hard drive and reinstall a fresh version anyway (because I like a challenge, sigh).
Now, went into Recovery (Command+Option+R) and tried to reinstall Lion using Internet Recovery (it said something about the item not being available etc).
So I decided to do it the old-fashioned way - and I erased the hard drive using Disk Utility (quite a stupid move I realise now).
So, at this point it doesn't boot, it shows something like apple.com/support -1006F with an exclamation mark across the globe and doesn't go any further.
It didn't come with anything but charger, so I don't have anything to restore it with... Did I brick it? Can I restore it from a USB or something (keep in mind I don't have anything supplied. Can I make one using Recovery Disk Assistant from my MacBook Pro, which is thankfully functioning well?).
How do I put an operating system on it now?

Some 2010-2011 models shipped with OS X 10.6 and received a firmware update after 10.7 was released, enabling them to use Internet Recovery. If you have one of those models, you can't reinstall 10.6 even from the original media, and Internet Recovery will not work either without the original owner's Apple ID. In that case, contact Apple Support, or take the machine to an Apple Store or another authorized service provider to have the OS installed.

How do I erase the Hard drive????

My iBook is about 4 or 5 years old with a brand new 80GB hard drive and brand new Charger plug. Now my logic board is broken and I don't want to put any more money in fixing it. So I just want to sell it but want to erase the hard drive first. Anybody can tell me how to do that?

ElkeTheStallion, welcome to Apple Discussions.
Here's how I understand your request.
You have an iBook that is inop due to a logic board failure. This precludes booting the iBook with a CD/DVD to use Disk Utility to erase the HD. You also can't boot the iBook in Target Disk mode to interface with your MacBook to erase the HD.
So your only alternative is to remove the HD from the iBook and install it in an external drive housing - USB or Firewire (best). Then you can interface the HD to your MacBook to retrieve the files & transfer to your MacBook & then erase.
These links give the instructions for removing the HD.

Suggestion - If you are going to sell the iBook for parts, don't reinstall the HD. It won't bring you much more $ in a laptop that won't work. Retain the 80GB HD and use it as a backup for your MacBook.

How can I securely erase the hard drive for PowerBook G4 running 10.2.3?

I'm about to sell a PowerBook G4 12-inch running 10.2.3 after I erased the hard drive via the the original software install and restore disk. There was no secure erase option like there is in subsquent versions of OSX. Is there a way I can do a 7 (or 35) time erase on this machine? Thanks!

See this Apple note. Secure erase was added in 10.2.3, but in a different place than later releases.

How can I erase the hard drive securely?

I want to sell my old iMac G3 with OS 9.2. First I'd like to erase the hard drive securely, so that no information can be recovered later. OS X allows you to do this easily with the Erase tab in Disk Utility. Can anyone advise how this can be done in OS 9.2?

Hi, iHope -
To do a reasonably secure wipe of the hard drive, use OS 9's Drive Setup utility while booted to an OS 9 Install CD - it's in the Utilities folder on such a disk. Select the Zero all Data item in the Initialization Options item in the Functions menu of Drive Setup.

I want to reinstall os X yosemite on my macbook Air but i erased the hard drive and i cant get the local recovery option; only internet recovery; is there any way to go back and get local recovery option?

i want to reinstall os X yosemite on my macbook Air but i erased the hard drive and i cant get the local recovery option; only internet recovery; is there any way to go back and get local recovery option?

Hi Bockworld1,
I'm afraid you did an error when erasing your hard-drive, this has automatically erased the "local recovery". In order to pass-by this, you must use a former Mac OS X installation DVD (such as Snow Leopard 10.6.3) and then when updated to 10.6.8 you may access the Mac App Store to recover the Yosemite Installer and proceed to a fresh "update" OR creating a Bootable USB Installation drive with DiskMaker in order to alway get a installation copy.
I also suggest you to create a USB Basic Operating System (you must select a local USB device to install Yosemite or whatever OS you want) with only the base operating system to launch your computer in case of Main Operating System issues.
Given the amounts of issues reported by users with 10.10.2, I command you to download 10.10.2 version to get a stable OS working.
Let me know how it is going.
Good Luck.

How do i erase the hard drive and reinstall?

How do i erase the hard drive and reinstall everything? My computer is running slow and i thought with having a 2.4ghz processor and 4gb of ram would make speed not a factor but obviously i was wrong in that my comp is running slow. Not as slow as my pentium processor desktop but its too slow for my tastes. Im waiting to get an external hd so i can save my songs and pictures to before i do erase everything.

Go to finder and in Spotlight, type in erase and install. The second choice is "Reinstall OS X. Print that out and follow the directions.
Good Luck.

How do I properly zero out or erase the hard drives in my early 2009 Mac Pro 4,1 tower?

How do I properly zero out or erase the hard drives in my early 2009 Mac Pro 4,1 tower?
I assume there are already instructions on Apple.com someplace but haven't seen them yet… I have to one terabyte drives one the operating system the other is blank I want to start fresh I want to zero out both drives but I didn't want to make any mistakes
I know I can use disk utility to 0 Out Dr., #2 that means I will have to take out the operating system hard drive out of my 2008 Mac Pro and put it into my 2009 Mac Pro to use the disk utility to zero out drive one the OS drive in my 2009 Mac Pro am my correct
I just need a little bit a help I want to go slow so I don't make any mistakes with the sleds or with the erasing process which journaled to choose encrypted or not etc. etc.
Furthermore is there instructions on the site on how to change the hard drive into a different sled because the sleds and my 2009 are different than my 2008 any advice
Thank you

I'm doing this because my friend told me that zeroing out the drive can nap bad sectors and also later for some kind of diagnostics usage of the drive or something like that he wasn't really clear
My friend was really specific he said choose the option that writes zero's once over the drive that is plenty good enough I was inclined to use the maximum seven write ...I just want to make sure the drive has no bad sectors and that's it's it's zeroed out for possible future diagnostics usage or something that he said was usable later
he also advised me to run a test on it but I don't have the software you mentioned or the software that he has… So I may have to take the drives over to his house unless you have some kind of free software that's easy to use that you could suggest that will not only zero out the drive but test the drive completely
I am completely new to Mac I'm no dummy but at the same time I'm not super technically capable I mean I can surprise myself I'm pretty good but I need a good teacher… How expensive is this lifeguard software?
Thank you

How do I erase the hard drive on my 2007 Macbook with operating system 10.4.11 ?

I am going to recycle my old Macbook and want to erase the hard drive. When I go into utilities-disk utility-click on Macintosh HD-and the Erase tab, the only active button is Erase Free Space. The Security Options and Erase button are not active. How can I erase the entire hard drive? The operating system is 10.4.11.

You have to boot to another drive. You cannot erase the drive to which you are booted. Typically you would use the system installer discs that were provided with the computer originally.
Alternatively you can use another computer which is running OSX and put the old one in Target Disk Mode. The old one will simply be seen as a normal hard drive which you can erase.
How to use FireWire target disk mode - http://support.apple.com/kb/HT1661 - includes description of hardware and software requirements.

Can you use a start up disc on an iMac without formatting the hard drive?

Can you use a start up disc on an iMac without formatting the hard drive?

Yes, because the startup disk is read from the boot rom, not the Hard Disk.
