Sapphire AMD Radeon R7 250 2GB DDR3 Not working Mojave 10.14

[trs96]

i forget to say, i am using VGA Port..my monitor has only VGA input

Not the VGA Port Apple dropped support for that 10 years ago. Use a digital connection if you want working graphics !

A DP to VGA adapter would be best. If not that try an HDMI to VGA adapter. Better yet, get a new monitor with HDMI.

Hi All, R7 250 2GB DDR3 working fine now with full acceleration QE/CI on HDMI port (VGA and DVI not tested) below are the steps i did

1. Uninstalled Mojave and Installed High Sierra
2. I manually edited two kexts AMD RadeonX4000.kext & AMD7000Controller.kext
3. Removed 68101002 and added 66101002 in the above two Kexts. After rebooting i had full graphics acceleration

For HDMI sound you could test with lilukext and AppleALCKext in Clover/Kexts/Other folder and in clover devices set audio inject to 1.
**Clover Configurator app in Devices.

That works for me with my 0x6810 card.
