> So, Apple recently stopped supporting the last version of OS X that would run on a 2012 15" retina MacBook Pro. You probably can still run the latest version of macos on that model using OpenCore Legacy Patcher [1]. My only issue is while GPU works for UI, macos video decoding service (VTDecoderXPCService) seem to stop supporting the gpu on my model and do all video decoding with software decoder, which leads to increased cpu load whenever any app display any video (e.g. when the settings app show some video preview in the trackpad section).
