Im using 8gb ram mac. docker on mac uses different virtualization technology than linux called hyperkit not as effective as on linux
8GB is too small for modern OS, especially for macOSX. With 16GB Docker works perfectly.
That is a good point. I believe that this is a hard requirement based on the applications you are writing and IDEs you are using. For simple Node.js Apps using an editor like VS Code, 8GB should be enough. On the other hand, JVM based apps would require a bit more memory for a smooth development environment.
