Casement for people switching from Windows to Mac

Keep your habits. Change your computer.

Updated October 9, 2026·1 min read
Short answer

Casement gives a Mac the Windows habits switchers miss: a layout picker you drop windows into, an Option-Tab switcher that lists individual windows, a list of an app's windows in the Dock, and one Dock icon per Chrome profile. Everything except the Chrome profile icons is free.

The two-week list

  • Week one: layouts and Option-Tab. These carry most of the muscle memory.
  • Week two: Dock window lists and Chrome profile icons.
  • Also learn ⌘ in place of Ctrl, and ⌘ ` for windows of the same app.

What Casement does not do

It does not add a taskbar, a Start menu or Windows-style menus. It is a small set of window behaviours, with the rest of macOS left alone.

Questions people ask

Does it change the look of macOS?

No. Menus and windows look the same; it adds behaviour only.

Try Casement

Casement is a menu-bar app for Mac that puts each Chrome profile in the Dock as its own icon and adds snap layouts, hover-to-focus, a window switcher, Dock window lists, a drop shelf and display controls..
