SDK Installation for MAC for Nano

Hello all, I have been trying to install the SDK based on the document
https://docs.nvidia.com/cuda/cuda-quick-start-guide/index.html#mac

I cannot find it searching the topics

I have downgraded Java to 1.8, put in the appropriate links to get past the Mac Catalina (10.15.4) limitations on /Developer … I can get Nsight to start with the

./nsight -vm /Library/Java/JavaVirtualMachines/adoptopenjdk-8.jdk/Contents/Home/jre/bin/java

it hangs on the first menu.
I try to compile based on the example:
make -C 0_Simple/vectorAdd

I get nvcc fatal : The version (‘11.0’) of the host compiler (‘Apple clang’) is not supported

OS 10.15.4
I loaded Java 1.8.254
Xcode 11.3.1

Any ideas how I get my dev environment up and running ? … just trying to use the single board computer :-) !

Thank you,

Peter
