Hello everyone,

It's been a couple of years since I did my last hackintosh install and I'm a bit rusty. Everything was running fine on previous install,Yosemite with Geforce GTX 960 and I've decided to do a High Sierra Fresh install on another SSD because of software support was terrible on an older system. I Record and Produce Music.

First attempt went well, but when done the system was unusable because of lags, beachballing everytime. Spent a couple of weeks trying different versions of Nvidia webdrivers thinking it was a graphics driver issue, with no luck.

Bought a new GPU, ATI Radeon RX 580, reinstalled High Sierra and got the same result. Now I don't know what to do. Graphics seems ok, using a ultrawide LG monitor plugged on displayport adapter to hdmi, 60hz (75 goes blinking). Spend the weekend tweaking bootflags, installed lilu/whatevergreen and again no luck :/

The Rx 580 should've native support, so I starting to think it is another issue. Attaching my config.plist and kext/other folder.

Any help is appreciated!

Edit: spelling.

I am using "HP 8100 CMT i7-870 RX460".
add: Clover r5119 & latest kext.
It seems that you need to use "SMBIOS = iMac11.3" for i7-870 for the settings in this guide to take effect.
