I have tried injecting a suitable UUID with smbios.list (following the format suggested based on my NIC MAC address) and it didnt work as expected, I still get the same kind of "_CFGetHostUUIDString: unable to determine UUID for host. Error: 35" errors when booting.
So if I understand it correctly its not posible to integrate superhai's SMBIOS' kext UUID injecting (the one that fixes those error 35 errors) into Chameleon's 2 smbios override?
