Hey guys.
Thank you for all of your hints and tricks. I got everything working on my E6410 Nvidia, nearly!
I can't get iMessage to work. Facetime and iCloud work without issues. I tried everything. Really, read a tons of tutorials. EthernetBuiltin, EFI, FileNVRAM, smbios, device-properties etc...
the device-properties thing is my last hope, but as many others, i have the issue of the black screen after boot when I have the entry in the org.chameleon file.
Maybe someone of you has something for me I missed and can try to get iMessage working.
