Is there any reason I should update from 10.7.3 to 10.7.4 or no reason and should I just be happy to run 10.7.3 as is? Is 10.7.4 too complicating? I just updated to 10.7.2 to 10.7.3 successfully today. I replaced the finder and machkernel than it worked. But than I had to install official Nvidia drivers which actually worked better than the Nvidia kexts I was using on 10.7.2.
