Hi. Happy to help, but the linked repository in GitHub does not work. Let me know how I can assist.

I am experiencing the same issue. Did you get this resolved?

Hi , I have been using R 4.1 and 4.1.2 without issues, and performing faster than a 6-core Windows system. This was on my M1 Macbook, but I have found no issues in my new 14" MacBook Pro. Can you explain what does "slow" mean for you? R is native, but RStudio is still not native, which means to use Tensorflow with R it needs to be done outside of the RStudio environment, as an example. Standing by to assist, Luis

RStudio and R both run, they are working under Rosetta2, but no issues with big models including some using H2O.ai. Good luck!
