"Mac OS X can't be installed on this computer"


I've just received a white macbook from my uncle and it has Mac OS X 10.5.8 on it. I purchased a legit copy of Mac OS X Snow Leopard so I could update my mac's software. The reason I'm upgrading to Snow Leopard is because all later mac versions including El Captain, require you to have at least Mac 10.6 to install. Once I proceed to boot from my Snow Leopard USB, all is well I select my language (English) then I wait for the install process to commence, but I come up with error,

"Mac OS X can't be installed on this computer"

Thats word for word what it says, I've looked at a bunch of other guides on how to fix this but none have worked! I've tried making sure that my Mac HDD is formatted to GUID Partition Table and I've made sure my Mac has the right specifications to support Snow Leopard but it just doesn't work.

Update (02/14/2016)

My problem is still not fixed. I've contacted Apple support and nothing!

Answer this question I have this problem too

Is this a good question?

Can you give us the full serial number. It's located in the battery chamber on the side.

Just to confirm- are we attempting to perform an upgrade to Snow Leopard or a clean install?

Also, what is the model number of this unit? Snow Leopard will not run on a non-intel Mac.

This is a clean install, and yes this is an intel mac! Thanks


Kurtis- when you reformatted the drive did you make sure to select the "root" or the actual HDD, not the 'Macintosh HD' partition. The entire drive must be formatted as GUID.

Sorry if this seem redundant, just want to confirm :)


Yes I did, and don't worry man I'm just trying to find answers :)


Just wondering if you have any other suggestions? Thanks


Last question, does this Macbook have at least 1GB of RAM? These units normally shipped with 512MB which will need to be upgraded if not already.
