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.

  • 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?
    -- Kaydell

    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.

  • 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.

  • 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.

  • 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.

    I just bought an iMac G5 with iSight. How do I wipe the hard drive and set it up as a new iMac

    Boot from your Mac OS X installer DVD.  After selecting a language, choose "Disk Utility" from the menu bar.
    When Disk Utility launches, use the "Zero Out Data" option under the Erase tab.  Erase the entire disk, not only the free space.
    One pass of zeros is secure enough for normal use.  One pass will take a couple of hours, so plan some time.

  • 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 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.

  • I have a late 2008 Macbook Pro last updated to Mavericks OS.  The screen died and it's not worth replacing.  How do I remove the hard drive and use a drive sled to access info I need?

    I have a late 2008 Macbook Pro last updated to the Mavericks OS.  The screen died and I took it into an Apple store and was told replacing the screen and the hardware to repair everything would cost almost as much as buying a new laptop or a cheaper model.  I was told that I can use a drive sled to access data I need on my hard drive. How do I remove my hard drive and use a drive sled to get to the information I need?  What makes matters more complicated is I need to update my iPhone and my iTunes/App store purchases.  How can I accomplish this?
    My wife has a late 2008 Macbook Pro as well, which I am assuming I need to run my hard drive.  Is there a way to just access just my hard drive without interfering with hers?
    I know this is lengthy.  Thanks to whoever looks at this and offers advice/instruction.

    the device you need is an External enclosure for a 2.5" (laptop form factor) SATA drive.
    A USB-interface enclosure will be slow, but is adequate for this task and for re-purposing as a backup drive later.  A firewire-interface drive would be faster, but is harder to find, more expensive, and faster than needed for this purpose.
    The drive will mount as an "extra" drive on your wife's Macbook, and you can drag and drop whatever you wish. You could create a separate Account for yourself on her computer, and use Migration Assistant or just copy your stuff over to the new account. Then it would not interfere with her files.

  • 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.
