MacOS is crazy efficient and can overcommit quite a lot.

I used an M1 Pro for a couple years to work. 8GB of ram but routinely using 12GB including swap.

Now, I couldn’t keep slack and outlook open so there were limitations but I was able to work. People are underestimating the usefulness of 8GB of RAM.

I guess it is also worth saying that I do my work by connecting to a remote server where I do the actual development and everything else. The Mac itself being a web browser and ssh machine
