It looks like a Mac. Underneath, it's Arch Linux, set up without ever opening a terminal.

Not a theme.
A desktop.
Most macOS lookalikes stop at the wallpaper and a set of icons. NiceC0re builds the menu bar, the dock, and the light that shifts when you drag a window into the desktop itself, not painted over KDE after the fact.

Light, bending
Nicec0re is built with Liquid Gel, a translucent material that blurs and bends the light behind every window, control and menu on screen.

The hard part's already done.
Arch Linux gives you complete control over your system, and it's just as well known for an install that reads like an exam. NiceC0re keeps the control and takes the exam off your plate.

A graphical installer
Handles partitioning and setup for you, so there's no wiki open on a second screen and nothing to memorize.

A rolling release
Install once and keep getting updates, instead of reinstalling from scratch for every new version.

The full Arch User Repository
Anything another Arch user can install, you can install too.
