Does PrimoDock replace the Mac Dock or sit next to it?

It replaces it. While it is open the Mac Dock stays hidden, and when you quit it comes back exactly as it was.

Does it work on an Intel Mac?

Yes. PrimoDock runs on Apple Silicon and Intel, with macOS 14 Sonoma or newer.

How to customise the Mac Dock, from Settings to a Dock with widgets

In System Settings › Desktop & Dock you can change the Dock’s size, magnification and position and have it hide itself. The Terminal goes a little further, like adding spaces between icons. Widgets, a Dock per context and themes take an app that replaces the Dock, like PrimoDock.

In System Settings

Open System Settings › Desktop & Dock. There you will find:

Size and Magnification, which enlarges the icon under the pointer.
Position on screen: left, bottom or right.
Minimise windows using the Genie or Scale effect.
Automatically hide and show the Dock.
Show suggested and recent apps in Dock.
Show indicators for open applications.

In the Terminal

Some settings have no button. Paste the line into Terminal and press Return; the Dock restarts straight away.

An empty space between icons, to separate groups:

defaults write com.apple.dock persistent-apps -array-add '{"tile-type"="spacer-tile";}'; killall Dock

The Dock showing with no delay when it is hidden:

defaults write com.apple.dock autohide-delay -float 0; killall Dock

And to undo all of it and go back to the factory Dock:

defaults delete com.apple.dock; killall Dock

What the Mac Dock does not do

A Dock per context. It is the same Dock at work, at home and in focus.
Widgets. No calendar, weather or song playing in the Dock.
Themes. It looks like the system, and that is it.
Change icons in bulk. Only one at a time, through Finder.

A Dock with workspaces, widgets and themes

Workspaces: work, home and focus, each with its own apps and windows. Turning on a macOS Focus switches workspace by itself.
Widgets that open: calendar, weather, music, battery and Claude usage, among 31.
Themes: Liquid Glass, Paper, Neon and the seasonal Halloween and Christmas ones, with snow, bats and fairy lights.
Icon packs applied in one click, and IconStudio to draw your own.
A pet on the bar: cat, dog, dragon or little ghost.
