This comment is a huge exaggeration of the effort it takes. You don't even really need full xcode to run terminal on mac.

There's options like Netlify to use as CMS: https://github.com/netlify/netlify-cms

Hugo will run anywhere.

In Linux you don't need to install the distro's packaged version; source is where you should go.

There is an added difficulty, but it's not as painful as you make it seem.
