Hello, I got everything up and running on a Mid-2009 Macbook Pro, 3.06 Ghz w/ 8 GB RAM and the Nvidia 9400/9600m card. I used Dosdude's method and only injected the 2 default kexts (boot.plist and legacy USB options) The only problem is that the recovery partition is giving me the grey circle and slash symbol. I have tried resetting the SMC and PRAM and attempted with System Integrity Protection both enabled and disabled but nothing is allowing me in. Audio, wifi, bluetooth all work fine. I should mention that I do have a USB 3.0 card in the PCI card slot but it is recognized in Sierra and I don't think it would be an issue. It is of a brand that requires no special drivers to work on Macs or Windows - never had one issue with it. Any ideas?
