Thanks for the hint. I am aware of this afecionados community. More power to them but none of this will make your old Mac grow an M1 processor.

My previous laptoop was an Macbook pro intel 64gb ram full specs. The M processor is much faster, even with just 16GB ram. Now if going strong means use the terminal, Vim etc. all is good.

If you use a laptop professionally you do want the latest updates from apple, not a Github repository.
