Also, clearly not designed for you? You can install Brew to have a package manager, Magnet to add Window snapping for a dollar, you can make it fit your use case for not that much effort or money. You don't have to use vanilla MacOS.
Furthermore, consider the alternatives. You've got Windows (bleh for a thousand reasons and clearly also not designed for developers), or you've got Linux (which doesn't have many of the apps you need, worse battery life, doesn't have Handoff to your iPhone). MacOS is the best all-rounder option for many people.
