Mac OS X 10.6.3 Installer says "Mac OS X can't be installed on this computer."

Hi, Ashton Neale here, I recently ran into a problem while upgrading my mac. I have a Mac OS X 10.6.3 Retail installer. When I create the installation disk and boot from it, it says "Mac Os X can't be installed on this computer." My 32gb flash drive is formatted as Mac OS X Extended (Journaled) with GUID Partition Table and when I boot up, I select main language and then it says "Mac Os X can't be installed on this computer." I cannot get to disk utility because all the utilities are grayed out, as a matter a fact, everything is. I researched for days and nothing helps. Here is my mac's info


Year: Late 2006 iMac G5

Processor: Intel Core 2 Duo

Memory: 1 GB 667 MHz RAM

Version: Mac OS X 10.4.11 Tiger

If you need more info, i can get it. (except system profiler is missing)

iMac, Mac OS X (10.4.11), Late 2006

Hi Ashton, as of note it's not a G5, G5s are IBM CPUs & can run no higher than 10.5.8


Is it for sure a Core 2 Duo?


How much RAM does it have?


Snow Leopard/10.6.x Requirements...


General requirements

* Mac computer with an Intel processor

* 1GB of memory (I say 4GB at least, more if you can afford it)

* 5GB of available disk space (I say 30GB at least)

* DVD drive for installation

* Some features require a compatible Internet service provider; fees may apply.

* Some features require Apple’s MobileMe service; fees and terms apply.

Hi bdaqua. I have already told you how much ram it has. And yes, it is an intel. I went to the apple menu and it showed "Intel Core 2 Duo" It has 1gb of memory, it has 209 gb available. I have a mac os x 10.6.3 retail installer.dmg. We have xfinity. And i don't use mobile me. I may have the wrong information because all i did was just look up late 2006 iMac and the pictures looked exactly like my mac. And once again i clarify, the cd is not grey, it is a white retail installation disk.

I don't know. I will look it up. I also have a mac os x 10.5.4 leopard installer retail.dmg but it needs to be converted to iso first. If I can convert that, then I can either stay with it or get 10.5.8 leopard and then upgrade. What could help is if you guys could find me a converter program to do it. When I use disk utility, It syas the dmg is not recognized. Thats because it needs to be converted but I don't have a program

Found it out, for those of you who have been following this post for an answer, this may be a bummer. Your Answer: Your computer can only run a 32-bit mac os x installation which snow leopard doesn't support. So, breaking it down means that you either have an Intel Core Duo, and not an Intel Core 2 Duo. But for all of you who came searching for this forum, the answer is Mac OS X 10.5 Leopard. I have enjoyed the operating system actually. Leopard has over 300 improvements succeeding its predecessor Mac OS X 10.4 Tiger. As for all Intel Macs that can't run OS X 10.6, you get boot camp assistant! This allows you to keep a partition of your hard drive for Windows. So Grab yourself an Installation Disk of OS X Leopard and upgrade your mac. NOTE: OS X 10.5 supports Power-PC based Macs!
