I have tried everything, Iboot, Empire EFI, Snow leopard for intel by hazard, nothing works, I been doing this for days. I am so frustrated. the Iboot does nothing, snow leopard never even starts, same with Empire EFI, the Hazard one instals but I get a kernal panic at second boot, I try different kernels and kexts options but always the something. Its a T61, intel core2, NVIDIA graphics, 4 gb ram, from all the posts I have read, and all the videos I have watched It should work...... any help please...... Thanks.
