I used Clover bootloader to install Mavericks to my build using the integrated graphics of my system (HD 4000) as installer wasn't giving any display. After setting up Mavericks completely and connecting my graphics card, clover boots up into a black screen (display goes on standby, if I type my password and press enter, the system works for a bit to open the mac desktop but the display stays blank). My system config is as follows: Core i7 3770 GA H77-DS3H 16GB RAM Gigabyte 7970 3GB (GV-7970OC-3GD) After searching around, my card is supported by Clover and Mavericks by default, so why can't I get any display on my main card? Any help would be greatly appreciated as I really need my graphics card to work with my hackintosh for editing and animation purposes. EDIT: I also tried connecting a GTX 660 to my machine and booting up with the display connected to 660. The hackintosh worked flawlessly. So what do I need to do to make it work with 7970? Thank you!
Hi, I've got an issue for which I can't seem to find a solution. I had OS X Mavericks 10.9 installed on a hard drive connected to my HP ENVY dv6-7247cl via a SATA-to-USB 3.0 cable. After using the 10.9.4 combo update, I get a black screen when I boot. I have sound (I can push the volume buttons on my laptop and hear the typical accompanying click), so I'm assuming I'm reaching the desktop fine. The screen, however, is absolutely blank. When I boot using verbose mode, I can spot no errors that might be related to the problem. In fact, the readout proceeds and ends like one would expect, only it's followed by blackness. The boot flags I currently use are -v, ncpi=0x2000, cpus=1, and dart=0. I've also tried GraphicsEnabler=Yes and GraphicsEnabler=No, though neither seems to help. Specs are in my sig. Any suggestions would be greatly appreciated! (Also, any fixes for those boot flags I'm having to use—cpus=1, especially—would be awesome.) Thanks, TatsuArekku
