How to Uninstall Tana on Mac

Export each Tana Outliner workspace you need as Markdown or JSON and open the downloaded file before removing the desktop app. A signed-out test cannot prove what a real workspace will sync or restore. The recorded test used a direct download, not a Homebrew installation.

Remove the app and inspect its data

In the workspace home node, complete the vendor’s export from the ellipsis menu and open the downloaded file. Then quit Tana Outliner and move Tana Outliner.app from Applications to Trash. The recorded display-name folder is Tana Outliner; the cask zap instead names lower-case tana, plus caches and preferences. Inspect both independently rather than guessing they are equivalent. Vendor guidance.

Check the result

ls -ld ~/Library/'Application Support'/'Tana Outliner' ~/Library/'Application Support'/tana

Run this read-only check after quitting the app. A printed path still exists; “No such file or directory” means that path is absent, while a permission error needs its own investigation.

If you installed it with Homebrew

The Homebrew cask has a zap list that includes Application Support/tana, cache, HTTP storage, logs and preferences; it differs from the observed Tana Outliner folder. Run the command below without --zap if you want to keep those files and inspect them separately. A manual --zap follows the whole cask list regardless of Mole’s checkboxes. Mole uses zap only when its targets are selected, owned and within the checked boundary; otherwise it removes selected remnants through its own flow.

brew uninstall --cask tana

What Mole lists

The display-name Application Support/Tana Outliner is a review row, unselected by default. Exact bundle-ID cache and preferences are normally selected; a separate tana folder needs its own ownership review.

What this test covered

The official 1.529.0 disk image supplied Tana Outliner.app, removed on September 20, 2026. The selected display-name support folder was removed. No account sign-in, export or workspace recovery was tested.
