Why cant I use GPU parallization with Matlab 2020 on my 2019 Mac Book Pro running 10.15.7?

Error using gpuDevice (line 26)

GPU acceleration with Parallel Computing Toolbox is not supported on macOS versions 10.14 (Mojave) and above. Support for

earlier macOS versions will be removed in a future MATLAB release.
