It’s not just Omarchy, there’s really not much out there in the desktop Linux sphere for those who are mostly happy with how macOS works out of the box. Everything is either in a similar vein to the Omarchy setup (hyper-minimal tiling WM), Windows-like (KDE, Cinnamon, most other DEs), or a chimera with a grab bag of design bits from every desktop and mobile platform (GNOME, Pantheon, COSMIC).
It’s a bit depressing because it means that if I ever feel forced to switch my daily driver, it won’t come without a dump truck load of friction, frustration, and lost productivity, which I’ve validated by using the various Linux desktops on secondary machines.
