    I've been through many threads and youtube videos about this upgrade and everyone seems to be able to do it just fine. I have a black macbook (2006). 10.4.11 OS X. 2GHz Intel Core Duo.

    I tried everything it seems. I backed up everything onto another hard drive, booted to the installation CD (Snow Leopard upgrade $29) at the start-up (pressing option) at startup with the CD inside. After clicking the language of choice, I get an error saying that it requires 10.5 or above to upgrade.

    The only options from this point is to restart the computer or restore from backup.

    I looked everywhere to see if people had a similar problem. Every video I saw did not have this prompt. They were able to get to the following picture instead to install.

    I have tried erasing my entire hard drive...and it still recognizes that it is 10.4. I've tried erasing the hard drive, disconnecting the backup drive, so the only thing it can start is the cd and it still knows it is 10.4.

    HELP!

    According to the photo you provided it only says that you must have 10.5 or later installed already; I don't see where it "recognizes that there is 10.4 on it." You have an upgrade disc which requires OS/X 10.5 already installed so that you can upgrade to 10.6.

    You will need the full install disc for Snow Leopard ($129) to put it on a freshly formatted HDD.

    Your understanding of this is incorrect. You cannot UPGRADE your existing installation. When you are on Tiger, you can only make a fresh installation of Snow Leopard, meaning that you have to format your hard disk first. Boot from the Snow Leopard DVD, run Disk Utility, prepare/format your hard disk and then the installation will work. Of course, you are well advised to make a full backup of all your data FIRST.

    So, of course you can use the 29 EUR/USD DVD and it is fully legit -- everybody who tells you different should maybe read the EULA of the 29 bucks DVD BEFORE they open their mouths. The thing is not sold as an upgrade, it is sold as a full retail version meaning that you do not have to own a previous version in order to be entitled to use it. End of discussion.

    However, Apple did not provide an upgrade mechanism for OS X versions prior to 10.5. Just like the Windows 7 installer cannot upgrade Windows NT, Me or 2000, for example. Or maybe just like Ubuntu Linux 10.10 cannot "upgrade" Debian Linux, although Ubuntu is based upon Debian.

    Long story short: You have to make a clean installation. (Which is the better choice anyway.)

    no he wont, the upgrade discs are exactly the same as the retail discs, the only difference is how much you pay.

    I did boot from snow leopard. That is where I ran into my first problem depicted in the first picture. The only way to get past that was to click "restore from backup" and then I was able to access disk utility on the menu to format my hard disk. Then the only option I could go from there was to restart my computer again booting up from the DVD (no other options...). Then the same prompt "Mac OS X can't be installed from this computer" popped up.

    Hi ISH1208. At last I have found someone with exactly the same problem. I bought my macbook second hand which came pre loaded with a 10.5 Leopard upgrade from Tiger. I recently purchased a Snow Leopard 'CPU Drop In" upgrade disc. The upgrade went awry because of a mistake by me. Anyway I lost Leopard and had to reinstall Tiger from the discs that came with the Macbook. I have tried numerous times since then to install Snow Leopard following various instructions from various forums, all from a formatted hard drive. Your first screen shot is exactly where I end up. I have no solution around this. Maybe the HD has to be totally erased by another method before booting up from the OS disc and then formatting the HD. I have had an offer to refund my money on the upgrade and buy a full retail install. Might end up doing this but I am sure from what I have read that I should be able to install 10.6 on to a clean HD.

    Hi Yukio. Not sure about partitions. When formatting from clean HD I just followed the recommended formatting.
