Unfortunately Apple has deprecated their OpenCL compiler, which is why Cycles doesn't support GPU rendering on AMD GPUs in Blender 2.80 and later. This was originally [announced on Blender's bf-committers mailing list ]]. This limitation is also documented in https:*docs.blender.org/manual/en/latest/render/cycles/gpu_rendering.html#amd and the [ https://wiki.blender.org/wiki/Reference/Release_Notes/2.80/Cycles#GPU_rendering | release notes for Blender 2.80 .

AMD
OpenCL is supported for GPU rendering with AMD graphics cards. Blender supports graphics cards with GCN generation 2 and above. To make sure your GPU is supported, see the list of GCN generations with the GCN generation and supported graphics cards.

AMD OpenCL GPU rendering is supported on Windows and Linux, but not on macOS.

Due to OpenCL compiler bugs and discontinuation of OpenCL by Apple it was disabled on macOS platform. Other platforms still support OpenCL.

You will either have to use an older version of Blender or use a third-party render engine like AMD Radeon™ ProRender that supports Apple's Metal API.
