For a new user, the most important things are usually a familiar feeling desktop environment, comprehensive default hardware support, and plenty of documentation in case you need it. The most important anti-things are needing to learn a bunch of new concepts right away, needing to use the command line, and experimental things that are known to break regularly.

Since you’re a Mac user, I would suggest KDE over Gnome for a desktop environment. Even though the default Gnome application bar looks very Mac-like and the default bar on KDE looks very windows-like, the rest of the KDE desktop feels much more Mac-like.

For the rest, you will want to use a common distro with a wide user base and a long history targeted at desktop users.

For those reasons, I would suggest either Kubuntu, or Fedora KDE.

Edit: When picking between those two, choose Kubuntu is you want to install the OS, and then not worry about major updates for several years. Pick Fedora if you want to have new features more often.

If you are ok with a more Windows-like desktop environment, Linux Mint is the go to option for an easy intro to Linux.

elementary os.

Stick with MacOS, Apple isn't shitting the bed nearly as hard as MS(lop). If you really want to switch, Mint is nice as a starter, and Bazzite, while intended for gaming, is mich, much more solid than I expected and is totally usable as a daily driver.

If you're used to the UI and UX of Mac OS and not Windows then almost any distro will be rough. There's Elementary OS that at surface level looks like Mac OS, but then you use the actual Linux programs and they're just Linux programs.

I would sugest debian, it has the same "just works"-feel to it, and the gnome desktop environment shares some design philosophy with macos. The main downside is that it is often a couple of years behind on software updates. Is this is a dealbreaker, I recommend mint for all, fedora when you need redhat-only software and debian-sid if you feel adventurous.

All that said, if you have a good mac currently, it has the same UNIX-benefits as linux. Using "homebrew" as a package manager and "better touch tool" for the desktop tweaks solves most problems, this is what I do. You may of course want to run linux only software, if this is you then double check if you also need an x86-64 cpu (as opposed to arm) before reinstalling.

I think the most popular one is similar- Ubuntu
