How to group windows on a Mac

Keep related windows together so they move as one: Stage Manager groups, app tabs, Spaces, and stacked or tabbed columns that share one place on screen.

Guide · Updated 13 October 2026

Some windows belong together: a chat app and its call, a spreadsheet and the report built from it. Keeping them grouped saves hunting for the second.

Built in ways to group

  • Stage Manager: drag a window from the side onto the stage to add it to the group in the middle.
  • Spaces: a desktop per group.
  • App tabs: Window menu, Merge All Windows, for apps that support it.

Stacks and tabbed columns

In ClutterFreeMac, ⌃ ⌥ ] stacks the focused window into the column on its left, so the two share the column's height and move together along the strip. ⌃ ⌥ ⇧ ] pops it back out. Make the column tabbed with ⌃ ⌥ ⇧ T when you would rather flip between them than see both.

You can also drag windows into stacks in Settings, Arrange, which shows your strip as a picture you can rearrange.

Questions
