Nope, but there is way less tinkering required than there used to be. For the last two years, getting going with modern peripherals and a browser/terminal/editor hasn’t involved any futzing (I use ThinkPads). Gnome is the standard for ‘Mac-like’ desktop environments on Linux, the version shipped with Ubuntu 18.04 will likely be well polished and welcoming to new users. Personally, if you like to avoid a mouse, I’d recommend a tiling window manager — the quality and range of these on Linux is just fantastic. The full concept doesn’t quite seem to exist anywhere else. Extremely un-friendly to a novice user, but extremely productive and enjoyable for ‘professional’ use.
