OS X Yosemite installer shows blank/black screen when using Clover

This is a heads up for everybody with an Nvidia GTX 760 (other Nvidia cards may be affected as well) trying to install OS X Yosemite 10.10 using Clover on a Hackintosh. If you’re getting a blank/black screen at the start of the installation, try to add the boot flag nv_disable=1. My screen was getting dark just after the installer displayed DSMOS has arrived when using the -v verbose boot flag. It always happened right after the installer was switching from text mode to graphics mode.

                <string>dart=0 -v kext-dev-mode=1 nv_disable=1</string>

Once OS X Yosemite has been installed, the nv_disable boot flag is no longer required and should be removed.

  3. Thank you so much, after all I finally managed to get the installation screen. But I have another question:
    You say that this boot flag should be removed after the installation. Can you explain how?
