Question 1

How is atrium different from macOS Spaces?

Accepted Answer

atrium keeps its own list of desktops instead of using Spaces. All of them live on your current Space: when you switch, atrium tucks the old desktop's windows out of sight and puts the new desktop's windows back exactly where they were. It doesn't use Mission Control at all, so its problems don't reach atrium.

Question 2

What's wrong with Mission Control and Spaces on macOS 27?

Accepted Answer

Many people on macOS 27 report slow, stuttering window drags between Spaces, apps forgetting which Space they belong to, black or blank desktops after a switch, missing thumbnails, trouble with more than one display, and Space shortcuts that stop working until the Dock is restarted. Reports continue on 27.0.1 and the 27.2 betas. atrium works the same on macOS 14 to 27 because it doesn't depend on any of that.

Question 3

Does it need me to turn off System Integrity Protection?

Accepted Answer

No. atrium uses only the standard Accessibility features of macOS to read and move windows. It doesn't need SIP turned off, doesn't use private interfaces and doesn't change the Dock.

Question 4

Why does atrium need Accessibility?

Accepted Answer

Accessibility is how a Mac app is allowed to see and move other apps' windows, which is all atrium does. It's required. atrium never reads what's inside your windows and never records what you type.

Question 5

What is Screen Recording used for?

Accepted Answer

Only for live thumbnails of your windows in the overview, and it's optional. Without it the overview shows each window's app icon and title instead. Nothing is recorded, saved or sent anywhere.

Question 6

What happens to my windows if atrium quits or crashes?

Accepted Answer

They come back. atrium saves which window is on which desktop as you go, and when it quits, crashes or your Mac restarts, every window it had tucked away is put back on screen. “Show all windows” in the menu does the same at any time.

Question 7

What about full-screen apps?

Accepted Answer

atrium leaves full-screen windows and windows on other macOS Spaces alone. The overview lists them as “outside atrium” so you can still find them.

Question 8

Does it tile my windows?

Accepted Answer

No. atrium keeps windows exactly where you put them. It's about desktops, not layouts.

Question 9

Which Macs does it run on?

Accepted Answer

macOS 14 Sonoma or later, on Apple silicon and Intel Macs. It's made for macOS 27 and works just as well on 14, 15 and 26.

Question 10

How much is it, and is there a trial?

Accepted Answer

$9.99 once at launch (the first 14 days), then $14.99. One licence works on 2 Macs, with no subscription and no account. There's no free trial: if atrium doesn't work for you, ask for a refund within 7 days.

Question 11

Where can I get it?

Accepted Answer

Only from tealmac.com/atrium. Moving other apps' windows isn't possible from inside the Mac App Store's sandbox, so atrium is sold and downloaded directly.

Question 12

Does atrium collect any data?

Accepted Answer

No. There's no account, no analytics in the app and no tracking. It goes online only to activate or check your licence and to look for updates. Your desktops and rules stay on your Mac.
