NVIDA Geforce GTX 750Ti graphics card wont work with El Capitan

[almusaka]

hello i have GTX 770 2GB

after update no screen signal shows.
so i used boot flag nv_disable=1
then boot with bad resolution
after that directly update graphics driver
if u don't have one go to
http://www.nvidia.com/download/drive...px/92173/en-us
and install it

last thing open MultiBeast and change system definition to Mac Pro 3.1

then restart and have fun

CTBM: if after all the things suggested you still get the prohibited sign, please boot in verbose mode and post a screen shot of the text when it freezes. Also note whether you're booting from the USB or system drive at the time, and whether you installed UEFI or Legacy.

Thank you for the reply. I just read that El Captain does not support alot of my music software at the moment so I just did a clean install of Yosemite.

Thanks for you help again
