Hi there.

The RX 550 chipset, if it is a Lexa core, is not supported in macOS.

It might be possible to spoof a "Baffin" core by adding the Device-ID (0x67ff) to your config.plist DeviceProperties. I say "might" because it is a spoof that is not guaranteed to work. But I see you haven't tried that anyway, so this explains the lack of acceleration and low memory count.

Thanks very much for the response, Once I updated the OpenCore to latest. will try to spoof and let you know the feedback. I saw some videos in the youtube where the Lexa card is being spoofed to Baffin

Thanks @Feartech @UtterDisbelief @P1LGRIM .

Finally I managed to make the card work on Big Sur with full acceleration. I followed the below Youtube tutorial. Its spoofing Lexa to Baffin. Anyone with my same model card can follow below youtube link make the card work.

Thanks All for your help.
