Install centos 6.0 x86_64 on mac

[coke]

I am trying to install centos 6.0 (x86_64) on my Mac. I got this error.

kernel requires an x86-64 CPU, but only detected an i686 CPU. Unable to boot...

My MacBook Pro has a processer Intel Core 2 Duo, 2.8 GHz. I bought in Decemeber, 2008. Does this machine support 64 bit guest os?

Thanks!

Use search functoion in this area. There were some threads about activating 64 bit mode in macos at bootprompt.

Try holding the 6 & 4 key down at MAC boot.

Try holding the 6 & 4 key down at MAC boot.

That trick doesn't work for all machines, and there is a piece of software that will help: http://www.ahatfullofsky.comuv.com/Engl ... S/SMS.html
