    Hello,
    I know this is old news, but I need to know if anyone found a solution how to make the Snow Leopard 10.6.3 DVD to work and to install the update I bought from Apple.
    I have read many many posts all over the web, and this seems to be a general issue, but maybe someone already found the cure of this problem ?
    Any tips will be appreciated !
    Bernie

    I never heard of what you are talking about, but maybe I don't understand completely.
    You have an Intel Mac, which hasn't or had Mac OS X 10.6 Snow Leopard installed and you want to use the 29 USD Snow Leopard Upgrade DVD to reinstall Mac OS X 10.6.
    What option did you choose? Did you do a clean install
    (Short version: Clean Install of OS X 10.6 Snow Leopard
    Long version: Mac OS X v10.6 Snow Leopard: How to Erase and Install)
    or did you just do an upgrade?
    And what upgrade did you buy? The Snow Leopard 10.6.3 DVD?
    Did your Mac come with Leopard or Snow Leopard?

    Thanks for replying.
    I do have an Intel iMac (20") that originally came with Tiger, now my actual version is OSX 10.5.8
    I bought the Mac OS X 10.6.3 Snow Leopard Family Pack ($49) because I have 3 Apple's in my household.
    What I did was, inserted the DVD and follow the instructions for upgrading the software, tried 5 times, read many posts on this forum and others, and many people had this issue before, sometimes it gives me an error message that I have to clean my disc, then after 20 minutes of installation, it fails and gives me another error like "some file clould not be loaded", then another error etc etc...... I know from what I read that this are common issues so I feel kind of frustrated because I have done almost everything in order to get the upgrade to work without any luck yet.
    Thanks
    Bernie

    If you have backed up all your data on that iMac (when did you buy it?), why don't you try a that clean install I linked to earlier?
    Or is that the method you are trying?
    Can you verify the DVD on another Mac via Disk Utility, to see if it is fully functioning?

    Disk is white with the snow leopard picture
    Bought it on Apple Store in Aventura Florida
    Mine is an iMac Intel ( 3 years old) with 4Gigas on RAM, don't recall right now the processor speed, HDD must be around 200gigs

    I tried 2 methods, first was only inserting the SL disk and start the upgrade process ( didn't worked) then I restarted the computer with the disk inside and hit the "C" letter when the computer was rebooting, that started like a boot disk, I thought I made it, but after 20min or so, it stoped and gave me another error message, so the only method left is to perform a clean install hiting the "Alt" button when restarting with the SL disk inserted, before I go that far I still have one last option that is calling the Apple Support 800 number by phone, they give 90 days free phone support to anyone that buy's an upgrade of the OSX, so I want to hear what do they have to say about it, they already told me that is a known issue, but I need to be on my computer in order to perform some tests ( now Im at work so I will have to wait...)

    buy a stick of 2 gb ram from ebay for around 20 dollars. put that in. install snow leopard than once it is installed. you can put all your ram back in.

    Pressing down the "C" key is to boot from an optical medium (CD or DVD) that is inside the optical disc drive (ODD), it has nothing to do with what installation method you decide to use.
    Pressing down the "OPTION/ALT" key during boot up shows you all connected bootable media, be it the internal HDD (Macintosh HD), the ODD or any external device you can boot from (external HDD, external ODD or USB flash memory thumb drive), it also has nothing to do with whatever installation procedure you decide upon.
    Starting the installer of Mac OS X 10.6 Snow Leopard from inside Mac OS X also has almost nothing to do with the procedure you use, unless you circumvent the UTILITIES button to start Disk Utility.

    Anyway, to do a clean install of Mac OS X 10.6 Snow Leopard, you have to start Disk Utility while booted from the installation DVD and erase the Macintosh HD partition.
    The proper steps are explained here:



    Does that mean, Mac OS X 10.6 Snow Leopard can only be installed on Macs with 2GB RAM?
    I installed Snow Leopard on a 2007 iMac with 4GB RAM, on a 2008 MacBook with 4GB RAM and on a 2009 MacBook Pro with 4GB RAM. The installation procedure went without problems.
    I used the DVD and a clone of the DVD onto an external FW800 HDD for that.

    Btw, to quote someone, just press the [​IMG] button.

    To quote several posts, use the [​IMG] button (multi-quote).

    To edit your posts, use the [​IMG] button.

    All these buttons are on the bottom right of the posts.

    or you can take out one ram stick...try the installation. if it doesnt work. put the ram you took out back in and try it with that and the other ram stick out. trust me i had the same exact problem.

    no snow leopard can be installed on a machine with a machine 2gbs or above.. 2,3,3,6,8 you get the point.... his imac only supports 4gbs... one of (or both of his) ram sticks are causing the installation to fail... he can try doing the install with either one in...and alternate. if that doesnt work he will have to buy new ram..( 20 dollars or so for a 2 gb stick)

    Okay, I wouldn't go as far as saying "no snow leopard can be installed on a machine with 2gbs or above ...", as in my experience it does, the Upgrade DVD I bought on the day of the release of Mac OS X 10.6 Snow Leopard worked with my 4GB Macs and the 10.6.3 Upgrade DVD I bought last week worked with my former 4GB MacBook. Therefore it works, for some at least.

    no man i wasnt saying snow leopard doesnt work on machines with only 2 gb... i was saying that 2 gb is the minimum. sorry for the confusion.

    I would say it's your optical drive.

    Try restoring install disk on a large thumbdrive / HD and install.

    Mistery solved, it seems like all the mess is a bad DVD disk, a new one is coming next week, we tried to run it in another computer and it failed, same error messages, so we (Apple support and me )are 99.9% sure is a bad disk.
    I will post results as soon as I get the new disk.
    Thanks all for your tips and advice's
