macOS High Sierra Hackintosh on Intel Core i7 8700K

macOS High Sierra on Intel Core i7 8700K

I decided to upgrade my 4th generation Intel core i7 4790K devil’s canyon to an 8th Generation Intel Core i7 8700K for macOS High Sierra Hackintosh. I’ve been using that 4th generation processor for almost 3 years and I wasn’t disappointed with my choice 3 years ago. Intel Core i7 4790K have 4.0 GHz base clock and 4.4 GHz boost Clock, It can be overclocked to 4.8Ghz. It was sufficient for my gaming needs before I started making videos and rendering scenes. 4 cores are somehow outdated if you’re a pro user and want to do multitasking like video editing, 3D modeling, rendering, animation and simulation for engineering projects. I was able to build a Hackintosh out of that 4th generation build with ease and I was using this for all of my video editing tasks. Intel HD 4600 and Nvidia Gtx 970 were more than enough for me while editing videos in 1080P and 4K occasionally.

This year I decided to upgrade to the latest core i7 8700K has more cores than previous generation processor. Also, It can be overclocked to 5.0 Ghz. Intel Core i7 8700K has Intel UHD graphics 630 which is much better in terms of performance. I also have the Ryzen processor but it is not feasible to make a Hackintosh out of it due to unavailability of Intel graphics.

macOS High Sierra Installation on PC using Unibeast, multibeast and Clover Configurator

macOS High Sierra installation was simple on this newly assembled computer. I’ve added complete macOS High Sierra Hackintosh system specification below. All you have to do is to follow the steps and you can create a Hackintosh without any hassle. The only issue is that I wasn’t able to get Msi Lightning 1080Ti working on this build. I’ll update as soon as I find any way to fix it.
