Hi, I've an AMD 6850 on Mojave and it work. Install the kext AMDController6000.kext, AMDLegacyFramebuffer.kext, AMDLegacySupport.kext with Kextwizard in System/Library/Extension, repair the permits and reboot.
With this process I've only a little problem with the animation.

Hey, thanks a lot for the help! I will give it a try tomorrow...

What kind of problems do you have with the animation? is it worth the transition from high sierra?

Thanks

The animation of launchpad is very slow and the tab of Safari is black and grey.

Thanks for letting me know!

It is because Mojave does not support Radeon HD6000 series.

tested my old HD 7770 card on Mojave

Hi there, I have been pulling my hair out trying to make this Radeon HD 7770 card work on Mojave. Curious what KEXT files you are using? I have been getting a display from Whatevergreen and I get mirrored dual display at 1024x768 using a kext I found called AppleGraphicsHD7750.kext.

I would love any advice getting this Radeon to work would be helpful since you seem to have this card running.
