Operating system disk help

My iMac came with the operating system already installed. Is it possible to order the disk online as well?

If your iMac came with Mac OS X 10.6 Snow Leopard, it would have come with the disks. Examine the items that came in the package and you should find them. If you no longer have the disks, having accidentally thrown them away, call Apple support and they can sell you a new set for a reasonable fee.
If your iMac came with Mac OS X 10.7 Lion or later, then Apple no longer supplies the disks. Instead they included the base files on a recovery partition, or you can use Internet recovery. See:

  • I got a flashing folder with a question mark. I got a new hard drive and upgraded to 4 gigs and can't open anything or reload the operating system? Help?

    I got a flashing folder with a question mark. I got a new hard drive and upgraded to 4 gigs and can't open anything or reload the operating system? Help? FYI: I have been using boot camp with windows 7 and started getting a kernal_data_Page_error and it would reboot windows, i was trying to do a chkdsk on the next reboot, but thats when i started getting this issue. I have put in a new hard drive and went from 2 gigs to 4. I can not get the computer to do anything, even the monitor does not show anything now????

    Prep your new drive:
    Drive Preparation
    1. Boot from your OS X Installer Disc. After the installer loads select your language and click on the Continue button.  When the menu bar appears select Disk Utility from the Utilities menu.
    2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area.  If it does not say "Verified" then the drive is failing or has failed and will need replacing.  SMART info will not be reported  on external drives. Otherwise, click on the Partition tab in the DU main window.
    3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID (for Intel Macs) or APM (for PPC Macs,) then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed.
    4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
    5. Set the format type to Mac OS Extended (Journaled.) Click on the Security button, check the button for Zero Data and click on OK to return to the Erase window.
    6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.
    After formatting has completed quit DU and return to the installer. Install OS X.

  • Do i need any of the operating system disks if I clean install?

    My MAcbook pro is getting serously slow esp on the internet. So from what I understand the best method is a clean install.
    However I do not have any of the previous operating system disks like Snow leopard and Lion. I am currently using Mavericks.
    My worry is that the computer will go back to it's original operating system (i think Tiger), and I will not be able to update to MAvericks because I don't have any of the operatings disks before that.
    Or maybe I don't need them? I have backed up everytjing on my computer and used time machine as a back up.
    Thanks in advance,
    L

    Did you do an Over the Top install? That is where you reinstall right over OS X that is already on your system.
    If you did and it ran fine for a day or so I suspect you are having some hard drive troubles. With an over the top install that replaces system files, OS X files, and makes them fresh. But if after a short while the system starts to run poorly again that comes from some corruption of those files. That only happens when there is drive problems.
    If after doing a real clean install, first erasing everything off your system with Disk Utility, you still are having slow downs first thing I'd do is check out the drive for errors and personally I'd replace the drive.

  • Can I use a mac pro operating system disk to upgrade a macbook

    I need to upgrade my 10.5.8 system to 10.6 before I can upgrade to Lion. I have a mac pro operating system disk for 10.6 can I use this?

    No. The gray-colored restore DVDs provided with a Mac are not the retail OS version. They contain only the drivers applicable for the purchased hardware, and the installer has a function to verify the hardware is of the type the disk was created for. If you attempt to use the Mac Pro restore disk on a different model Mac, it will simply refuse to install.

  • Original Operating System Disks and Restore CD's

    Trying to determine and locate the proper operating system and restore disks for an ibook G3 800mhz 12" Don't want to waste money on the wrong disks. Can any one identify the part number on the original os disks and the restore Cd's?
    Thanks in advance for the replies. This forum has helped alot if the short time I have been a Mac user. I wish I jumped sooner. Two Macs at home now and counting. This laptop is so good I cannot wait to upgrade to something even newer!

    If you try to obtain them anywhere except from Apple (the best option, probably), keep in mind that there were two different versions of the 800 MHz G3 iBook. The first version has a Combo drive (reads DVD's; reads and writes CD's). The second has a CD-ROM drive (reads CD's only). The second version will not be able to use the system discs for the first.
    In order to avoid this confusion, contacting Apple to see if you can get the discs directly from them is likely the best option.
    Good luck.

  • How/where can I get an operating system disk for 2007mid iMac that I installed new hard drive on

    I installed a new hard drive in my iMac 2007mid .Adventurous..
    I am told I need the operating system now.   I am behind a few upgrades due to needing the new hard drive..
    suggestions please?

    You can install from any full/retail installer DVD. If you have no discs, then you can purchase replacement discs from Apple:
    Apple Store Customer Service at 1-800-676-2775 or visit online Help for more information.
    To contact product and tech support: Contacting Apple for support and service - this includes
    international calling numbers..
    You can also purchase a retail Snow Leopard DVD:
    You can purchase Snow Leopard through the Apple Store: Mac OS X 10.6 Snow Leopard - Apple Store (U.S.). The price is $19.99 plus tax. You will be sent physical media by mail after placing your order.
    After you install Snow Leopard you will have to download and install the Mac OS X 10.6.8 Update Combo v1.1 to update Snow Leopard to 10.6.8 and give you access to the App Store.

  • Lost system disks - help!

    I have a G4 at work that was running 9.2.2 and recently the hard drive died. My system disks have been 'borrowed' and not returned by someone so IT Support have tried installing 9.1 disks from an earlier Power Mac onto the new hard drive but that doesn't work. They also think a generic 9.2.1 disk won't work either. Is that right and if so how can I get hold of the right disks? Thanks!
    G4 Mirrored drive doors   Mac OS 9.2.x  

    Hi, Neet -
    Welcome to Apple's Discussions.
    ... IT Support have tried installing 9.1 disks from an earlier Power Mac onto the new hard drive but that doesn't work. They also think a generic 9.2.1 disk won't work either.
    Is that right and if so how can I get hold of the right disks?
    If the G4 in question is a Mirrored Drive Door (MDD) model, then yes, that's correct.
    The original disks that came with the machine installed a model-specific version of OS 9.2.2. No earlier version will install - and there are no retail (universal) OS 9.2.2 Install CDs.
    The only source for a bootable OS 9 install for those models is from the original disks that came with the machine. You may be able to get replacement original disk by contacting Apple's Customer Support -
    http://www.apple.com/contact/phone_contacts.html
    <hr>
    If you need OS 9 solely for use as Classic under OSX, there are other possibilities -
    • copy a working OS 9 System Folder from another machine (OS 9.1 or later; OS 9.2.x would be better).
    • copy the System Folder from an OS 9.2.1 Install CD. Note, though, that there are very few control panels and extensions in the System Folder on an OS 9 Install CD; many services will not be available.
    OS 9 System Folders retain their integrity and functionality when copied using a simple Finder copy process (drag and drop) - cloning is not necessary.
    However, neither of those two options will result in a bootable OS 9. If you need a bootable OS 9.2.2, you will need to use an original disk set for that model.

  • No Lion Operating System Disk(s) with my new MacBook Pro?

    Hi, Just bought my wife a new MacBook Pro yesterday.  We are probably old school but we were both surprised to NOT find Lion OS disks in the box. 
    We called the Apple Store where we made the purchase and they told us they were not currently shipping Lion OS disks with new systems??? 
    How can obtain OS disk(s) for Lion and her new MacBook Pro?
    Optional purchase?  A website for a download?  Anyone else run into this situation?
    Thanks in advance for the help.

    Hi luke: Yes I know how you feel. I felt thesame way when those forst imacs came out with no floppy disk drives and with a read-only optical one. But now you can't find floppies anywhere xo life goes on.
    In any case you can, at least, make your own recovery disk. I did it and it works just fine. Here's a set of directions that I followed that I copied from some poster (sorry but I lost the originator so can't give him credit).
              •.          Purchase and download Lion from the Mac App Store on any Lion compatible Mac running Snow Leopard.
              •.          Right click on “Mac OS X Lion” installer and choose the option to “Show Package Contents.”
              •.          Inside the Contents folder that appears you will find a SharedSupport folder and inside the SharedSupport folder you will find the “InstallESD.dmg.” This is the Lion boot disc image we have all been waiting for.
              •.          Copy “InstallESD.dmg” to another folder like the Desktop.
              •.          Launch Disk Utility and click the burn button.
              •.          Select the copied “InstallESD.dmg” as the image to burn, insert a standard sized 4.7 GB DVD, and wait for your new Lion Boot Disc to come out toasty hot.
    It is important that you burn your Lion boot disc or backup the Lion installer prior to installing Lion itself. If left in the Applications folder the installer will be removed after the Lion installation is completed. If you are reading this article after upgrading to Lion all is not lost. A fresh copy of the Lion installer can always be redownloaded from the Mac App Store by clicking on the Purchased tab with the Option key held down.
    With the Lion boot disc you can boot any Lion compatible Mac, and install 10.7 just like you installed previous versions of Mac OS X. You can even use Disk Utility's Restore function to image your Lion boot disc image onto a external drive suitable for performing a clean install on a optical-drive-less MacBook Air, or Mac mini. Clean installs with Lion are easy once you find where Apple has hidden the boot disk.
    Hope this is useful to you.
