Did You Find A Way To Change The "System" Rt Variables ?Did everything as it says, bt my about mac system info shows my hackintosh as imac 12,1, and I've set it up as imas 14,2.
Any idea why?
Any system definition that uses ECC RAM (i.e. MacPro5,1/6,1) has the potential to cause problems.
You would have to delete the AppleTyMCEDriver.kext or use the Clover patch to avoid it.
MacPro is not really appropriate for a NUC anyway.
Look at everymac.com or the free Mactracker app and choose a system definition that matches your components as closely as possible.
If you want to install Sierra it should also be that of a Mac that qualifies for the operating system :
