smorf Posted October 4, 2012 Share Posted October 4, 2012 i just upgraded my hackintoshs hardware, and set up a fresh 10.8.2. i put in a new Geforce GTX 550 Ti and got it running by - installing the new released cuda drivers from nvidia - adding the correct vendor/device IDs in NVDAGF100Hal.kext´s Info.plist - setting "GraphicsEnabler=Yes" in my boot plist It worked and was recognized correctly. After a few regular reboots it broke. it shortly shows "...nVidia ROM patching failed..." at start of the boot sequence (just after chimera boot screen). When I do a verbose boot, it really boots, even loads the nvidia kext. At the point it should switch to the graphical part / login screen, my display just goes black and says "no signal". I tried everything, even a new installation. same thing. it works a few times, but after a while it just gets broken again. ideas anyone? i´m already considering changing the graphics to radeon HD5770... thanks in advance! smorf Link to comment Share on other sites More sharing options...
RobertX Posted October 4, 2012 Share Posted October 4, 2012 have you tried with GraphicsEnabler=No? ...just suggesting as my card requires no injection or enabler... Link to comment Share on other sites More sharing options...
smorf Posted October 4, 2012 Author Share Posted October 4, 2012 i did try that within a boot prompt. but thanks, good hint. i´ll try again with changing this in the boot plist. I will also try with different display devices on DVI/DP/VGA. Actually i am using a full HD display on DVI and a projector on VGA. i´ll check what happens if I change this.

RobertX Posted October 4, 2012 Share Posted October 4, 2012 ...perhaps you could also try chameleon boot-loader with graphicsenabler=yes... 1 Link to comment Share on other sites More sharing options...
smorf Posted October 5, 2012 Author Share Posted October 5, 2012 chameleon and graphicsenabler=yes did the trick. thanks. it gets recognized with the wrong amount of RAM (1,5GB instead of the real 1GB), but it seems to work for now. i think i have subversion of the gtx 550ti, that is not very common. (dev id 0x1244 - Manufacturer Palit with 1GB RAM, DVI, VGA and HDMI) but fine for now. i almost had sold this card.... :-) Link to comment Share on other sites More sharing options...

smorf Posted October 8, 2012 Author Share Posted October 8, 2012 okay. next problem. after installing chameleon the graphics card works. but i get kernel panics on boot from time to time. sometimes my system just comes up after the third try. they seem to be randomly - but sometimes the error message tells me that it was unable to load applertc.kext . ideas? robert? ;-) Link to comment Share on other sites More sharing options...
RobertX Posted October 10, 2012 Share Posted October 10, 2012 hmm...another thought... do you use the boot flag "UseKernelCache=Yes" ? it solved my boot hangs... Link to comment Share on other sites More sharing options...
smorf Posted October 13, 2012 Author Share Posted October 13, 2012 yep. but i think i found the cause. since i had minor audio problems, i removed voodoohda.kext. my system appears to be stable for the last few reboots. i use a usb audio dongle at the moment and i am still in search for a working audio kext. i already tried a few. voodoohda was the solution that worked best, but it had some background noises. so i used a patched voodoohda kext, which i found on kexts dot com. as i removed voodoohda, my onboard audio device AND the audio device on the graphics card are not recognized. maybe they are interfering...
