marco.pisellonio80 Posted October 29, 2013 Share Posted October 29, 2013 Hi all, I tried to install Mavericks DP on desktop in my signature and it didn't work good, i had several kp so I decided to wait for the final version, but with the 10.9 DP my GPU worked natively. Then I trid with 10.9 final version downloaded from Apple store, but cause inattention i mistake the choose of partition to install, instead to select an empty partition I selectet the ML 10.8.4 one without format it. At reboot all was chaotic and there was no graphics acceleration. "About this mac" showed 10.9, but the desktop was the old one and all was slow with many crashes. Too bad, I thought, I'll re-format and re-install all. Incredible, I re-created pandora installer for ML 10.8.4, I repeat all I made previously... and GPU does'nt work! For ML 10.8.4 I opened another post here http://www.insanelym...-installazione/ and here http://www.insanelymac.com/forum/topic/293307-ml-1084-no-graphics-enabled-after-installation-mistake/ Here I hope to resolve with 10.9. My Nvidia 220GT always worked natively, since s.leopard going through lion to ML 10.8.2, 10.8.3 e 10.8.4 that I subsequentely installed, I never had to put any kext or graphics enabler. Since I mistake that installation there is no way to enable GPU, I tried to initialize partitions, to format, to change hard disk, nothing. Now starting in verbose I read that GPU is recognize (I have a patched DSDT), but graphic acceleration does'nt work and resolution is only 1024x768. I tried to enable graphics options in pandora post-installation and chameleon wizard, ma nothing changed. Waiting for help... Thank you all.

marco.pisellonio80 Posted October 29, 2013 Author Share Posted October 29, 2013 Thank you PimentelX86, I can upload my kext tonight, if it's installed, I'm not home now. But I seem to remember that it's not in S/L/E. In S/L/E there are some Nvidia/Geforce kext. I have to delete them? Link to comment Share on other sites More sharing options...
Pimentel Posted October 29, 2013 Share Posted October 29, 2013 Hello. Why doesn't have there? All kext nvidia graphics are in S/L/E... Look: You need have all GeForce and NV inside S/L/E... No, you don't need delete nothing, you need have all this. Link to comment Share on other sites More sharing options...
mediamac Posted October 29, 2013 Share Posted October 29, 2013 Hi, I have 8600GT and i tried many methods that previously worked (nvenabler,Inject etc) but on mavericks none is working and there is no video acceleration.So please be patient and this is a common problem. But for now i am using these kexts (credits goes to the original uploader) Try installing all these kext using kext wizard with backup option enabled. Now the video is working perfect but i am getting kernel panic frequently. I hope this helps. Thank you Link to comment Share on other sites More sharing options...
marco.pisellonio80 Posted October 29, 2013 Author Share Posted October 29, 2013 mediamac the strange thing is that not even M.L. 10.8.4 works! Thank you, I'll try Link to comment Share on other sites More sharing options...
iFIRE Posted October 29, 2013 Share Posted October 29, 2013 your problem and to others users is that when you create your USBInstaller with Pandora, this not copy the info.plist to all Garphics kexts ATI* Intel* AMD* NVDA*, is a bug with Pandora, you can try copy from USBInstaller/S/L/E all NVDA kexts and install to your System with KEXT WIZARD app/repairpermissions/reboot, I had the same problem.
