Groupy for Mac: why there isn't one, and what to use instead

If you have moved from Windows to a Mac and gone looking for Groupy, you have probably already found the bad news. Here is the whole picture, including the part macOS does give you for free.

Short answer: Groupy is a Stardock product for Windows 10 and 11. There is no Mac version, and none has been announced. macOS has its own window tabs, but only inside a single application — so the thing Groupy is actually for, dragging a browser and a terminal into one tabbed window, needs a third-party tool on a Mac.

What Groupy does on Windows

Groupy's whole idea is one gesture: drag one window onto another and the two become a single window with a tab for each. From then on they move, resize and minimise together, and you switch between them the way you switch browser tabs. It works regardless of which applications the windows came from, which is what makes it useful — a document, a folder and a chat window living in one frame instead of three.

That is a Windows shell feature. It has no macOS equivalent from Stardock, and running Groupy in a Windows virtual machine on your Mac only groups the windows inside that virtual machine. Your Mac applications are invisible to it.

What macOS gives you already

Before reaching for anything third-party, it is worth knowing that macOS has had window tabs since Sierra, and a lot of people never find them.

In an application that supports them, Window > Merge All Windows collapses every open window of that app into one tabbed window. You can set the system-wide preference in System Settings > Desktop & Dock > Prefer tabs when opening documents, which controls whether new documents open as tabs automatically.

Two limits decide whether that is enough for you:

If your windows are all from one Apple app, macOS already solves this and you need nothing else. If the problem you actually have is five different applications sprawled across a display, native tabs will not touch it.

Getting the Groupy gesture on a Mac

Tack is built around the same gesture, because it is the right one: pick up a window by its title bar, drop it onto another window, hold for a moment, and the two become a group with a tab strip above them. There is a picker as well — ⌃⌥⌘G — if you would rather choose windows from a list than drag them.

It groups anything with an ordinary window, whether or not that application ever heard of tabs, because it arranges windows through the macOS Accessibility API instead of asking each application to cooperate. That is also why it asks for Accessibility permission on first launch: moving another application's windows is not possible without it.

Things that are genuinely different from Groupy

Two honest differences, since you are coming from something you already know:

Common questions

Is Groupy available for Mac?

No. Stardock builds it for Windows 10 and 11 only, and has not announced a macOS version.

Can I run Groupy on a Mac through Parallels or Boot Camp?

You can run it inside the Windows session, where it will group that session's windows perfectly well. It cannot group your Mac applications — it never sees them.

Does macOS have anything built in?

Yes, within a single app: Window > Merge All Windows, in applications that support it. Across applications, no.

What about Mission Control, Stage Manager, or a tiling window manager?

They solve a neighbouring problem. Mission Control and Stage Manager arrange and reveal windows; tiling managers place them side by side. None of them collapses several windows into one frame with one tab per window, which is the specific thing Groupy does and the specific thing people miss.
