Custom / Auto-Named Desktops

Name a space yourself, or let Tatammi name it from the app and document in front of you. You navigate by intent, not by counting swipes.

Every desktop, named, in the menu bar

One glance tells you what each desktop holds, without switching to it.

Straight there. No animation detour on the way, and nothing opens first.

Two ways to rename one

In the menu or the panel, wherever you already are. Both open the same field on the row.

Pricing

One purchase, yours to keep, on up to three Macs.

You opened your Mac with something to do.

Then came the rearranging. Find the document behind the browser. Resize both so you can see them together. Swipe through desktops hunting the project you were working on ten minutes ago. Do it again when the next task needs a different set of apps.

Each one is small. Together they are the gap between deciding to work and working, and you cross it a dozen times a day.

Two modifiers, one rule

Every shortcut in Tatammi obeys the same split: ⌃⌥ brings something to the desktop you're on, ⌥⇧ arranges what's already there. Learn that once and you can guess the rest.

Hold ⌃⌥ and the lit keys act on the desktop you're on: which one it is, what it's called, and what you bring to it.

For the techies

What it asks of you

what the others want first a config file YAML scripting disabling SIP what Tatammi wants: a menu-bar icon. That's the install.
Quiet

A menu-bar app, not a project

No config files, no YAML, no scripting, no disabling system protection. Light and dark, VoiceOver support, native throughout.

Questions

Why isn't this on the Mac App Store?

Because it couldn't be. Reading and controlling Spaces needs private macOS frameworks that Apple bars from the Store. That's also why an app like this can exist at all.

Is it safe to install?

Yes. Tatammi is signed with an Apple Developer ID and notarized by Apple, so it installs without warnings.

What does it need access to?

Accessibility permission, which is what lets it move and resize windows. Nothing else. Your work stays on your Mac: the only things Tatammi sends are an update check and a licence check. Details on the privacy page.

How is this different from yabai or AeroSpace?

Those are powerful and expect you to configure them. Tatammi has opinionated defaults, no config file, and doesn't ask you to disable system protection.

Which Macs does it run on?

macOS 13 Ventura or later, on Apple silicon and Intel.
