I've tried upgrading from Lion to ML. I got it installed fine and entered the Multibeast options as well as the Kextbeast kexts. When I boot from HD all I get is a white screen.

I followed these instructions

When I first tried to install I couldn't get past the white screen so I followed this tutorial

http://www.tonymacx86.com/mountain-...mountain-lion-6xxx-gpu-issues-fix-inside.html

That worked to install but now I can't get past the white screen after I use Multibeast and Kextbeast I've tried using the GraphicsEnabler=No command at the Chimera screen but that does nothing.

Can someone please help me out? Thanks.
 
No one has any ideas?
 
Is there more info that someone needs??
 
Dude I have exactly the same issue...and guess what...NOT ONE reply. Im starting to lose faith in this site...

Good luck and if you get it working please let me know.
 
.and guess what...NOT ONE reply.

Probably because this has been hashed out before and you were expected to use search.

Try key words 6870 installation issues
Some had to use boot flag framebuffer=duckweed (or other frame buffer name), some just needed GE=Yes, some had to delete a kext and add it back after install. Seems to depend on the OEM and the GPU id.

If possible, suggest you install using CPU graphics and add the GPU after you get up and running.
 
Thanks for the response.

I DID use search and all I saw was lots of comments like mine, no actual replies which offered anything I hadnt already tried. I have actually fixed the problem now.
