High Sierra CPU recommendation.

[Kentsoon]

I am running High Sierra on an i7 2700k sandy bridge. I want to upgrade the CPU and Motherboard to a faster Performance.
I also have a z490 i9 10850K Machine. But High Sierra wont install on that.


What is the last CPU, Motherboard Generation I can run high Sierra on??

Actually, it is possible to run High Sierra on a system with Intel 10th generation hardware like what you have, as demonstrated by this thread :

[GUIDE] OC 10.13.6 Z490 Gigabyte Aorus Xtreme + Core i5 10400 / i9 11900K + Nvidia GTX 1060

Not long ago, it was said that it was impossible to boot a Z490 based 11-gen system on High Sierra, and it was also said that it could not run Opencore. Well folks, this is the guide you've all been waiting for! This system is both High Sierra AND Mojave compatible...

But you will need a supported graphics card as the CPU integrated graphics are not supported. Also you will need to use OpenCore (or perhaps Clover 5124 and later) as bootloader as plain old Clover won't work.

Personally, I recommend using 300 series motherboards and Intel 8th / 9th generation i3/i5/i7/i9 CPUs with a supported graphics card to run High Sierra 10.13.6. They are relatively easier to setup, and you can still use plain old Clover if you want.

My first three systems are based on them.

^Interesting.... and just maybe what I am looking for (CPU Spoofing to install older OS).

Thank you.
