bluesyblues Posted October 3, 2013 Share Posted October 3, 2013 Help is critically needed! Thank you for reading. So, I got this old beast the "Dell Workstation 690" Successfully installed Mountain Lion 10.8.2 The problem is, whenever the nVidia kexts loads the screen goes black while I am almost sure the system loads flawlessly but I can't see it. I tried all the nvidia drivers be these stock OS X or retail nVidia. Doesn't help. Went through all I could find regarding this issue but still no help. The graphics card installed is nVidia GT 630 4GB Appreciate some help Thank you Link to comment Share on other sites More sharing options...

The graphics card installed is nVidia GT 630 4GB Appreciate some help Thank you Don't know what boot-loader you are using but if you go to /Extra and find org.chameleon.Boot drag it to the desktop open it with text edit change UseKernelCache=No GraphicEnabler=Yes PCIRootUID=4 . Then drag it back it into /Extra this solved my boot problems. I also removed the darkwake=0 from the file. Here is what I am using <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>EthernetBuiltIn</key> <string>Yes</string> <key>GraphicsEnabler</key> <string>Yes</string> <key>Kernel</key> <string>mach_kernel</string> <key>Kernel Flags</key> <key>Legacy Logo</key> <string>Yes</string> <key>Timeout</key> <string>2</string> <key>UseKernelCache</key> <string>No</string> <key>PciRoot</key> <string>4</string> </dict> </plist> You can also use F8 and type those commands in manually to get it up and running.
