I want to share something with the forum about high sierra installation
My pc specs are quite towards the low end
intel corei3 4160 3.6 ghz
DDR3 ram 1600 Mhz 8 gb Dual channel
nvidia Graphics Card GT1030 2gb
2 TB of hard drive 7200 rpm
When i went to install High sierra 10.13.6 with the premade iso I was getting stuck at " Macos can not be installed on this computer..."
Then I downloaded 10.12.6 olarila and installed it, it went ok with minor problems like getting stuck at the Gigabyte motherboard page for inifinte, I resolved it by clearing CMOS manually and plug-out plug in of rams..
Then from 10.12.6 I flashed 10.13.6 high sierra app to upgrade, and it went fine. But before the installer restarts I did two things-- unchecked the nvidia web driver option from system variables and copied the contents of EFI partition into the EFI of Highsierra EFI.
But when I arrived in the new system 10.13.6 the version was showing 17G66.. I doubt that whether there is actually any version like that exists at all. However finally I downloaded a 2 Gb update from store and installed it and arrived at the version 10.13.6 (17G13035). Then installed nvidia web driver and also installed required kexts by Vietnam tool.
