Tried the graphics update - first destroyed my system. Then patched, didn't improve. Then applied rumar's method (removing the GE and NV kext)
and it booted. Then I installed zeph's nvinject installer (which had previously worked on my system), and while it doesn't destroy it (it still boots fine), it doesn't work either. System complains that 'nvinject was installed improperly".
What should i do?
