Hello good, these days I have been investigating to put in dual boot with Windows 10 a version of Mac OS X. I carried out the installation of Catalina and it worked for me more or less, because having a GTX 970 I had to do a fix so that they were installed the drivers, but then it produced visual bugs. I have decided to download the High Sierra version since it is the last one that has native support for NVIDIA Drivers.
The problem is that I install it without problems, and while I start it from the USB from which I installed it works but when I start it on the hard disk with Clover it tells me "This version of Mac OS X is not supported on this platform".
When I boot from the USB, the SMBIOS says that it is a 17 "iMac, while if I start it with the hard disk where it is installed it puts a different one.
How can I solve that?
