I Just donwload the elementary iso (the latest), flashed on a Usb with rufus, and try to install on my MacBook pro from 2008. It has a intel 2.4ghz Core 2 duo, GeForce 8600 gt and 4 gb ram. Aparently everything should work.
I have manage to load the grub screen, with a good resolution and working good. I have try all the options. Try, install año OEM and the result os everytime the same: a blank screen.
I think, it may be an issue with the vídeo drivers but i don't know how to fix it.
Thanks you for the support!
