greenyfreak Posted June 23, 2009 Share Posted June 23, 2009 Hi! I tried to install the Nvidia 8500 driver with efistudio, I found the instructions on this forum, but now after rebooting I can no longer start mac. It always hangs on the apple symbol... Does somebody know how I can delete the driver again without formating the whole system? Thanks in advance Link to comment https://www.insanelymac.com/forum/topic/171972-nvidia-8550-gt-problems/ Share on other sites More sharing options...
greenyfreak Posted June 23, 2009 Author Share Posted June 23, 2009 Does nobody know how to backup my system, or how to delete the new drivers in command promt, (because I can enter command promts when I start with the -s option)? Please help me, I really need your help!!!! Link to comment https://www.insanelymac.com/forum/topic/171972-nvidia-8550-gt-problems/#findComment-1184167 Share on other sites More sharing options...
