Apple has made massive improvements and regular upgrades to macOS since 10.6. I'm not really sure what you are referencing when you say otherwise, but as a Mac user full time at work and at home, you're simply totally wrong. Windows 10 is quite usable, it's in use all over the world by millions of people. The home versions force a reboot when upgrades are required, but even those upgrades and the associated reboots can be delayed 35 days. The enterprise versions and pro versions can be completely controlled as they should be. Forcing upgrades is probably the best thing MS has ever done for the general security and health of the internet. Linux is still today a piece of shit, as it has always been. Apple ships zsh, not bash. If you want an upgraded version of bash you install home-brew and do brew install bash. Done. Or just use zsh because it's better. If you are an xfce linux on the desktop user, you are very out of touch with modern operating systems.
