How do you install Snow Leopard on a Raid 0

Hey guys
I have a MBpro 13" 2011 with Lion currently installed (the MBpro was shipped with snow leopard)
I bought 2 SSD's and I'm trying to make a fresh install on the MBpro. No backup, time machine, images, or anything like that.
Questions:
can I install it from an external hard drive? or do I need an external DVD player?
how do I configure the empty drives in RAID 0 before starting the installation
thanks

how do I configure the empty drives in RAID 0 before starting the installation
The support for creating RAID 0 Striped or RAID 1 Mirrored is included in Disk Utility. Disk Utility is available on the Installer/Utilities DVD (or its equivalent if copied to and then booted from an external drive). normally, you would Boot from the Installer/Utilities DVD, but do not install. Answer only the "what Language" question, and wait for the MenuBar to be drawn. Choose Disk Utility from the Utilities menu.
After you have created a striped RAID from two SSDs, they will show up as one Volume, onto which the Installer can Install.

  • How do I install snow leopard on a 2.1 ghz macbook with 10.5.8 Leopard installed?  I have a 10.6.2 unstall disk.  It says it can't install snow leopard on this computer.

    How do I install Snow Leopard on my Macbook 2.1 ghz, with 10.5.8 Leopard installed?
    I have the install disk for Snow Leopard 10.6.2, but when using it for installation, it
    states that "Snow Leopard cannot be installed on this computer"!
    I understand some features of iOS5 cannot be used unless my iMac and Macbook have
    10.7 Lion installed.  Correct?

    It sounds like your Snow Leopard install disk is the disk that came with another model of Mac (grey lable with no pictures). If so, that's not legal and won't work. You need a retail (white label with the picture of a snow leopard) copy of the installer for each system that didn't come with Snow Leopard.

  • How can I install Snow Leopard on my 15" MacBook Pro without using its DVD drive?

    How can I install Snow Leopard on my 15" MacBook Pro without using its DVD drive?

    I'm assuming your dvd drive is broken? if you have a thumb drive large enough (8GB or better), you can use another computer to make a bootable image from the install dvd to the thumb drive. then you can install from the the thumb drive.

    Hi.
    You simply can't. Snow Leopard is compiled in Intel binary only.
    Good Luck.

    Apple figures that having supported PowerPC code for the last 6 years is enough so they dropped it.
    Why should they have to support some that old forever? It doesn't make good business sense to support some that so few will use.
    If you must play those games, my suggestion is to get an older Mac that will support PowerPC. It is going to be a difficult task to get Snow Leopard to run on a new Mac.

  • Can you install snow leopard on Intel based mac with less than one GB of ra

    As the subject relay I have an Intel mac mini with 750GB of ram? will th einstaller let me install Snow Leopard?

    No, the installer will not let you install Snow Leopard on an Intel Mac with less than 1 GB of RAM. Even if it did, performance would be unacceptable & the OS would probably be unstable.
    If you want to run Snow Leopard you will need to upgrade to at least 1 GB of installed RAM. If you want it to run efficiently, you should install more. Typically, 2 GB will get you most of the benefits of a larger memory space but if your Mac supports more & you want the best possible performance, install the maximum the Mac can handle.

  • How do I install Snow Leopard while keeping files, applications, and settings

    I need to update my system, I realized that I need Snow Leopard (quiet late) before Maverick. My question is, how can I install it keeping files and all the data. I found this on Internet, does it work?
    Install Snow Leopard while keeping files, applications, and settings
    If you follow these steps, the installer will replace your operating system if one is already present, but will preserve your account information and personal files.  You may have to reinstall some applications, however.
    Insert the install disc (or the first install disc if you have more than one) into your disc drive. Restart your computer while holding down the c key. This causes your computer to start up from the install disc rather than your hard drive. When you see the gray Apple insignia, release c . 
    The Mac OS X installer should open automatically. Follow the on-screen prompts to read and accept the license agreement and begin the installation. When prompted to choose a destination disk, select your preferred location and click Install. 
    When the Mac OS X installation finishes with the disc, restart your computer. After the installation completes, a configuration program may begin automatically if you are installing for the first time. You will need to supply basic setup information for your computer. 
    Update your system software to ensure that you have the most recent operating system components.  From the Apple menu, select Software Update... , and then follow the instructions on the screen. Often, you will have to restart your computer, and you may have to run Software Update multiple times before it can completely update your system.

    That's why you need to back it up. You won't need to restore the backup immediately afterwards unless something goes wrong during the upgrade, but you'll need it later; the drive will eventually fail.

  • How Best To Install Snow Leopard For A Non-Techy?

    What is the best route to go down to install Snow Leopard please? I received my copy on Saturday but I'm apprehensive at installing it!
    When I installed Leopard I ended up with a lot of problems, some of which are still not resolved, such as the non-recognition of log-in passwords etc. I still have to provide a password when switching back and forth between users and in order to close down I have to log out all users individually!
    As a keen Mac-user (but by no means a technical expert) I would like my Snow Leopard experience to be as painless as possible, so how best to install it please and at the same time eliminate my old Leopard problems outlined above?

    For the most painless upgrade possible, I suggest you just follow the instructions under the heading "Upgrading Mac OS X" in the Snow Leopard Installation Instructions document.
    As a precaution, you may want to run Disk Utility's "Repair Disk" step first. You can also run the "Repair Permissions" step if you want but I doubt that is necessary.
    Your 'old problems' aren't problems, AFAIK. You must always provide a password to change accounts & all accounts must be logged out to shut down or restart the computer. These steps insure the privacy of each user's account & make sure each user has a chance to save any open documents before the computer shuts down. IOW, they are desirable features, not problems!

    Switch off your computer, hold down the option key (usually the key between the ctrl and the cmd keys).
    Keeping a finger on the option key, press the start button.
    Keep holding the option key as the computer re-boots.
    Eventually you will be presented with some options on the screen, one of them will be to restore from Time Machine.
    No, you missed a step.  You'll see the Recovery HD as one of the options.  From that, you can reinstall Lion or restore a Lion Time Machine backup.
    But do not use that procedure to restore a Snow Leopard backup;  instead, use the procedure in #14 of Time Machine - Frequently Asked Questions.

  • How do you reinsatll snow leopard from an external optical drive

    Both my hard drive and superdrive crapped out. How do i reinstall from an external USB optical drive?  I am having a complete brain **** at the moment!

    If your replacing your internal hard drive, why not also get the Superdrive replaced?
    The OS X install disk supposedly won't boot from a external optical drive, only the internal one.
    To OS X onto your new internal drive, your going to need another Mac with optical drive to take 10.6 off the disk and place it onto a bootable USB. Any Mac should do, as the 10.6 installer isn't going to be booted .
    http://www.maciverse.com/install-os-x-snow-leopard-from-usb-flash-drive.html
    Other methods, requires another compatible Mac.
    If you have machine specific 10.6 disks and you have another exact model of Mac, you can use a SATA to USB adapter (or enclosure) to use boot the second Mac with the disk and install 10.6 on the "extenral" drive, then place it back inside the other Mac.
    If you have the 10.6.3 white retail so called "upgrade disk" for 10.5 (it also has the full 10.6 on it) and you have another Intel Mac that it's OS X version originally came with anything 10.6.2 or earlier, then it will boot that disk to install on the "external" drive, then it can be placed back into the other Mac.
    How to erase and install Snow Leopard 10.6
    Another internal drive access method is to use Firewire Target Disk Mode
    http://support.apple.com/kb/HT1661
    Also one can use a external drive to install the compatible OS X version onto, then option key boot the Mac with the new drive off the external, install Carbon Copy Cloner and clone the extenral to the newly formatted internal drive.

  • How do I install Snow Leopard on a MacBook Pro currently running Lion?

    A friend is having trouble running older apps in Lion on his new Macbook Pro and wants to revert to Snow Leopard. Any suggestions or cautionary tales appreciated. Thanks.

    New MBPs require a version of Snow Leopard that you cannot purchase. If it did not come pre-installed on the computer then installing Snow Leopard is a bit of a chore.
    First off he will need a computer that can boot from a retail Snow Leopard DVD (10.6.3.) Second off he will need a 16 GB USB flash drive or a free partition on a USB hard drive that is at least 16 GBs in size. The basic process is:
    Using a computer that can boot from a retail Snow Leopard DVD you install 10.6.3 onto the spare drive. Download and install the 10.6.8 Combo update. Create a new partition on the MBP. Boot the MBP from the 10.6.8 USB drive then clone the system to the new partition on the MBP.
    I will be glad to provide more detail if needed.

  • How do I install Snow Leopard? I am currently in Tiger

    Hi there!
    I'd like to know the best way to install Lion. My first generation MacBook white can still run the OS ( I have checked the specs) but the problem for me is that I cannot seem to find a way to install Lion directly since I am still on Tiger.
    I have searched Google and saw that the method is to upgrade to Snow Leopard and then Snow Leopard to Lion. Is this true? Or is there any other way to bypass this painful process?
    I am posting this as a question about installing Snow Leopard on my mac since I have not found a way to install Lion directly.
    Any help or input from you will be greatly appreciated.
    Thanks!

    You would need to purchase the Lion installer on a USB stick for $69, then boot from that and  erase Tiger in order to install Lion.
    btw, you keep quoting Tiger, but your profile says 10.5.8 which is Leopard. The answer is the same, whichever it is.
    The normal way is to buy Snow Leopard for $29, install that in place (without erasing anything), update to 10.6.8 using the combo installer from Support Downloads, then sign up to the App store and download Lion for another $29.
    I don't buy the 10$ saved, since you could make your OWN usb stick install for just the purchase of Lion.
    Oh another thing, Lion is not the same price as SL, it's 29.99

  • How do I install Snow Leopard using another computer?

    My 2009 MacBook meets all the criteria for the Snow Leopard upgrade, but my dvd drive is broken. Every time insert the dvd it is spit out (it is the same for audio cd's as well). I have tried repairing the drive and installing snow leopard using an external dvd drive (with no luck). I need a simple guide for using another computer to do the upgrade. My boyfriend has a newer MacBook Pro and I believe is operating on Lion. I want to use his computer to upgrade mine, is it possible eventhough we are on different operating systems?

  • How do I install Snow Leopard on a partition in Lion?

    I need my AppleWorks! This is what I've done thus far.
    I have a brand new 21.5" 2.5 GHz Core i5 running Lion. I made a 20 Gb partition on which I would like to install Snow Leopard so that I can run my beloved AppleWorks. I NEED the drawing program.
    I inserted a Snow Leopard install disk and restarted holding the C key. I get what looks like the Lion version of a Kernel Panic every time. It never goes to the SL disk.
    When I just open the SL disk under Lion and try to open the SL install app I get "You can't use this version of the application Install Mac OS X.app with this version of Mac OS X. You have Install (sic) Mac OS X.app 23.1."
    I've also tried booting while holding the option key to select the SL cd and I've changed the boot disk in SysPrefs to the SL disk, all with the same kernel panic result.
    Any suggestions welcome!

    The fact that you can't boot directly into the Snow Leopard disc without a kernel panic suggests that the SL disc you are using is not compatible with your hardware. Did your new machine come with Lion pre-installed and are you trying to use a SL disc that came from somewhere else?
    Even if this is the case, there still might be hope. This support page
    Mac OS X versions (builds) for computers
    contains the following entry for the newest iMacs:
    That indicates that your machine model was introduced before Lion was released, and originally shipped with Snow Leopard 10.6.6. Although it's possible that the hardware was changed for the machines that are now shipping with Lion, there is probably a reasonable chance that the hardware is the same, and that your machine can still run Snow Leopard. You would need the machine-specific OS X 10.6.6 Snow Leopard install disks that used to come with your particular model though - a retail Snow Leopard disc is OS X 10.6.3 and is too old for your machine, and an install  disc that shipped with a different model Mac won't work either. If this is your situation I would call Apple, give them your machine serial number, and see if there is a replacement set of Snow Leopard discs available for it.
