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
On each workspace’s home node, open the ellipsis menu and choose Export workspace as Markdown or Export workspace as JSON, wait for completion, and save and verify the download outside the removal folders. Markdown exports link to image/video files rather than including them, so save wanted linked media separately; the current JSON export is not a file users can import back into Tana themselves. 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.
After quitting, copy wanted local state from the paths below to an independent private backup outside the removal folders and verify it. In Finder, press Shift + Command + G to open each path or its parent, then move only existing unneeded app-specific items to the Trash. Keep shared parents and other apps' files:
~/Library/Application Support/tana~/Library/Caches/inc.tana.desktop~/Library/Caches/inc.tana.desktop.ShipIt~/Library/HTTPStorages/inc.tana.desktop~/Library/Logs/tana~/Library/Preferences/inc.tana.desktop.plist~/Library/Application Support/Tana Outliner
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 skips --zap when its list reaches unchecked or shared data, or a removal scope it cannot verify; selected remnants still follow Mole's own removal flow.
brew uninstall --cask tana
What Mole lists
With Remove data and settings with apps off, the listed Tana Outliner support review row starts unchecked; with it on, an eligible existing own unshared row may start checked. Verify an independent backup before deletion and uncheck data you want to retain. 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.
