I can confirm the patcher tool does NOT work correctly with the MacBook 4,1. I have both a black and a white one. The installer USB made from your tool boot to a prohibited sign on both of mine. I had to manually add the Mac identifier and model information to the Platformsupport.plist on the USB drive itself. I also replaced the prelinkedkernel with the file provided earlier in this thread. Once those were done, the USB installer WILL boot and has mouse and keyboard support, as well as working USB. Went through the entire installation process, rebooted to the installer USB, ran the patch command, everything completed with no errors. However, upon booting to the hard drive, no mouse/keyboard/USB working. Replaced the USB kexts on the hard drive with the ones from earlier in the thread and got kb/mouse/usb back. Still no Webcam/Audio/Wifi. Patch updater did not fix any of those items. Manually installed the BM4321 fix, now have Wifi working, still no Audio/Bluetooth/Webcam. Closer for sure, but definitely not as easy as it should or could be. Ran Geekbench just to test and got a score of 1582 Single / 2710 Multi Core. This is with 6gb and a 2TB ssd, 2.4Ghz C2D
