Hello,

I am kind of new in mac business but I think I am advanced user in computers technologies...

I am trying to get OS X working on my old machine its AMD (i know right lol) Phenom II X4 940, 4GB of RAM and at last point Gainward GTX260 896mb.

At the moment I am running Niresh`s Maverics successfully updated to 10.9.5 (13F34). I use MacPro3,1 in SMBios. OS X shows my graphics as Nvidia Chip Model 3MB

However, with my knowledge I am not able to get graphics acceleration working.

GraphicsEnabler=Yes won`t get my system started.

I installed the system only with /amd64 and the installation went fine.

But I keep getting that black / no signal error.

Only thing how to get OS X load is to backup grafix kexts or use nv_disable=1.

So I downloaded nvidia web drivers and installed them with no problem at all, but it helped nothing... I changed to nvidia web driver in nvidia driver manager which also shows in ECC section no devices at any slot... Then I tried booting with nvda_drv=1 but it is all the same...

I know it is kinda odd - this combination AMD and 260 but I want to give it a shot and do not give up easily...

Thank you for all answers...
