How to rebuild OS, without installation disk(s)?

I recently purchased a Mac Pro.  It did not come with a restore installation disk.  If I needed to rebuild my OS, how do I do it without installation disks?

Restart with the Option key held down and use the preloaded recovery partition. If that becomes unavailable, the computer will download a new one from Apple's servers.

  • HT4561 Install OS 6.8 without installation disk

    I need to wipe my MAC Pro clean and do a fresh OS install before I put it up for sale. I don't have any OS installation disks. The current OS on the system is 10.6.8. How can I do this?
    Thanks guys!

    You cannot do this without having the Mac OS X installer from which to boot. Unless you made a copy of the installation disks to another drive, you will need the installation disks. You really should provide them with the sale in any case. If your Mac shipped with Mac OS X 10.6.x, you can call Apple support and ask to purchase a new set of the install disks. If your Mac came with an earlier version of Mac OS X, you can order a retail copy of 10.6 from the Apple Store.

  • Reinstalling Mac OS X without Installation disks?

    I have an iMac flatpanel OS X 10.4.8 256 ram. Ive had it for around 5 years.Its very slow and crashes alot.
    I have no files I want to keep and want to clear the computer fully off. I have misplaced the installation disks that came with the iMac
    How could I reinstall this iMac without the original installation disks?
    Where can i buy, download etc?
    Please help

    Hi vamos!
    You could call Apple and see if you can get a set of replacements discs, for a small fee, or Tiger is available for purchase at The Apple Store (U.S.).
    If you know what to look for, a Full Retail Version, of the Tiger Install DVD, can also be purchased rather inexpensively, at some online Apple retailers, Amazon, eBay, AppleRescue, FastMac, etc.
    Be sure not to purchase grey, upgrade or machine specific CDs or DVDs.
    The discs should look like the images in the above links.

  • Can I restore from Time Machine without installer disk?

    Laptop is mounted in FW target mode to Mac Mini, which in turn is connected to Time Capsule containing laptop's backups.  Is there a way to restore laptop's HD from TC without having a Mac OSX installer disk?

    It won't be recognized, because of a different MAC address. So the easiest way to restore the Laptop is to boot it from installer disc and restore the Backup.

  • Can I repair my startup disk without installation disk?

    Disk utility is showing me the following after I ran "verify disk":
    The volume Mac HD was found corrupt and needs to be repaired.
    Error: This disk needs to be repaired. Start up your computer with another disk (such as your Mac OS X installation disc), and then use Disk Utility to repair this disk.
    I don't have the installation disk.  Is there a way to repair the disk without the installation disk?  I'm running mac os X 10.6.4.
    Also, I'm very new to mac OS so please keep any answers/help simple for me.  Thanks.

    If you have a TM backup on an external drive, restart the computer and hold down the option key. You will get a selection of drives. The TM drive has a recovery drive also. I think it will be listed as Mac OSX. Select it and try booting from it. Your internal drive might be bad and not allowing you to start from that recovery drive.

  • How to install OS in a new HD from iMac to a MacBookPro without installation disk

    Hi guys, please I need some help
    I have a MacBook Pro and an iMac.
    The iMac is running OK with the latest OS.
    The MacBookPro have the HD replaced by a new SSD model from Crucial, because the original was failing...
    Now I need to install the OS in the new HD on the MacBookPro (which I already replaced) connected with the iMac via Target Mode (?) without the installation DVD because I dont have it right now.
    How can I do this?
    Thank you

    You are going to need the OSX installation discs that came with your MBP, install OSX Snow Leopard from the disc, then update it to 10.6.8 using software update. Then buy Mountain Lion from the Mac App Store and install it.
    You may not use the copy on the iMac for this, it is a violation of the terms of the license.

  • How to move Adobe Reader 8 to new PC without installation disks

    Just got a new computer.
      I've got the new computer and the adobe on the old one.  I don't have the disks anymore... can I move it over some how?

    You DO realize that Adobe Reader is a free product and can be downloaded from the Adobe site, right?
    And I suppose it's possible that you got version 8 on disk but that's not common. Are you sure it's Adobe Reader you have and not Adobe Acrobat?

  • How to install bootcamp drivers without installation disk?

    Look as a part of right click-2fingers at a same time you should press on the touchpad.
    and check your macbook,the slot where you put the speakers wire if the drivers are not install then a red light will come from it and if not then it means that the drivers are all install.
    and try to install the drivers from http://support.apple.com/downloads/#bootcamp
    Hope your problem get resolved.

  • Upgrading suspect hard drive on SL510. How to do this without install disks ?

    Hi,
    My SL510 (supplied Fall 2010) has always had problems with HDD. Latest issue took a complete re-image to resolve followed by 0.5 day to restore files from back-up). I no longer have any trust in the HDD, but the rest of the machine works fine. 
    According to several other posts I reviewed on here, most notably this one ; it seems to be a feasible task to :
     1) Acquire a new HDD, SSD seems to be a popular choice.
     2) Use Acronis True Image or Clonezilla to make a complete image of the (failing) HDD to an external USB drive and make a boot CD.
    3) Put new HDD into SL510, boot from CD and use the cloning s/ware to image the old HDD onto the new one.
    Seems reasonable and straightforward. However I have a few questions :
    1) Has anyone actually followed above steps and can report success and/or gotchas ?
    2) My main concern (and it applies even if I don't have to change the HDD), is that Lenovo did not supply appropriate recovery media with the laptop, nor even anything obvious like a licence key on a sticker on the laptop.
    While the SL510 has Win 7 Ultimate, the R&R disk and the Product Recovery CDs provided are both for Win XP and have never worked with the laptop. There was a Recovery partition on the HDD as well, again this never worked that I could figure out, and somewhere along the line it got trashed (my fault), and no longer exists.
    So, for instance on the most recent recovery from an old system image, Windows decided my O/S was potentially not genuine and I had to go through a painful re-validation step.
    How can I be sure this issue will not come back to haunt me either at a point of upgrading or some other time ?
    Can I raise a ticket with Lenovo (and if so where) and request that they provide appropriate recovery media or licence key for my device ?
    Appreciate hearing from anyone with prior experience and/or Lenovo service desk person who can shed any light on the above.

    u can make recovery cds from the rescue and recovery in the control panel. your sticker with the license for windows is under the battery. I am currently trying to image one also, we'll see how it goes...

  • How to install CS3 without a disk

    Hello,
    A few years ago I purchased Adobe Design Premium CS3. Since then I purchased CS4 Design Standard and recently on my new iMac Pro i installed CS5 Desin Standard.
    I want to reinstall Dreamweaver, from my old Design Premium CS3 bundle, on my new iMac. I have the CS3 serial but not the install disk. I don't seem to find a CS3 download on the Adobe.com website. And is it even possible to install a CS3 Dreamweaver next to my CS5 Design Standard bundle?
    Sebastiaan

    I have the CS3 serial but not the install disk. I don't seem to find a CS3 download on the Adobe.com website.
    Old versions are not available for download, unless you purchased the download then you can re-download for up to 3 years.  Something important to note is that the installer for upgrades does not require the older version of the software to be installed on your computer.  As long as you have a valid serial number you should be able to install the program with the old serial number.
    And is it even possible to install a CS3 Dreamweaver next to my CS5 Design Standard bundle?
    Yes.  The only thing that cannot be done is running multiple versions of the same program at the same time, for instance Photoshop CS3 and Photoshop CS5.  They would be allowed to run separately but not at simultaneously.
    One thing you should note is that DW CS5.5 is part of Design Premium Suite.  The $399 upgrade from your CS5 Design Standard would give you InDesign CS5.5, Photoshop Extended, Flash (Pro & Catalyst), Dreamweaver and Fireworks.

  • Archlinux Won't Boot With Or Without Installation Disk

    At first my laptop started to turn on and off by itself. So I reseatted the ram to see if that was the problem. After a while, it started to tell me to put a disk or some "media device" inside of the computer to get it to run. I mounted my partitions and checked /etc/fstab to find that it was absolutely empty as though I had never genfstab'd in the first place.
    I gen-fstab'd like one usually would when installing arch after mounting all partitions and swapon. While mounted, I also update the system, re-installed base base-devel and then restarted. I left the disk in for good measure to see if it would load that up, as without it that I couldn't access my bios. Now, I see a message that says
    boot:
    When I try to "Boot existing OS" off of the grub menu of the live CD. And hints or tips?
    It also doesn't seem to be a hardware issue but a kernel one. Because when I type in "linux" in front of the colon it'll tell me that "linux" is not found. Also, if that were the case I doubt that I would be able to mount my partitions and find all of my files there still.

    it isn't load grub
    enter on boot : u will seen some word like "no kernel install"
    if that right u should reinstall grub2
    https://wiki.archlinux.org/index.php/GR … ode_region
    may be it is a bug ,  cause use grub2 with mbr
    hope to help , try it.

  • Mac OS X 10.5: How to get a replacement installation disk?

    Well this is more than a little embarrassing, but I took in a couple recently because the woman was being abused by her own family and they feared for her safety and life. I treated them just like a daughter and son-in-law for over a month. They finally found jobs and a new place to live, so they moved out hastily one weekend, leaving some of their stuff...and taking some of mine. We won't talk about what was missing, except for some reason, one of the things they took was my OSX 10.5 startup disk for my nearly new MacBook Pro.
    Can I get a new start-up disk for it in case I need it? Where do I order that?
    And where can I find a large supply of faith in humanity that is gone now?

    Contact them if possible; otherwise, phone Apple(1-800-SOS-APPL in the United States) and ask for a replacement.

  • How to set up without reformatting disk?

    Hi There, When I try to run Boo Camp Assistant on my Macbook 10.5.6 It tells me that it "The disk cannot be partitioned because some files could not be moved...use Disk utility to formate as a single Mac OS extended (Journaled) Volume, restore your information to the disk and try Boot Camp Assistant again" I'm nervous about doing that. Is there any safer work around? Thank you, Joanna.

    Hi,
    if you trust iDefrag http://www.coriolis-systems.com/iDefrag.php enough, you might wanna buy.
    But the backup/restore approach is usually cheaper and IMHO more trusty.

  • How Do I Download Without a Disk Drive - CS 5.1 Ext. Educational Edit.

    When a new laptop is purchased they rarely have internal disk drives, so the disk option is impossible.  I searched for this specific program type and I cannot find it.  Can anyone provide me with a download link to Adobe Photoshop CD 5.1 Extended Education Edition?  Thank you for you help.

    Here is the link for cs5 downloads. I did not see an educational version though. Perhaps same software just license number determines which you have? (Guessing)
