How to Uninstall Postico 2 on Mac

Postico 2 can save database connection favorites and query history. Export wanted favorites before removal, handling any included passwords as sensitive data; uninstalling the client does not remove a PostgreSQL database. The recorded test used a direct download, not a Homebrew installation.

Remove the app and inspect its data

Quit Postico 2 and move Postico 2.app from Applications to Trash. Inspect its sandbox container and preferences before selecting local-data removal. The cask identifies a Postico container and plist. The vendor documents favorite export and encryption. Vendor guidance.

Check the result

ls -ld ~/Library/Containers/at.eggerapps.Postico ~/Library/Preferences/at.eggerapps.Postico.plist

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 Postico application scripts, container, cache, preferences and saved state. 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 postico

What Mole lists

The exact Postico container and preferences are normally selected. If the container holds local favorites or history, back it up or uncheck it before removal.

What this test covered

Postico 2.3.3 from the official package was removed on September 20, 2026. No database connection was made; a 108 KB container hit a Trash permission error, so that test did not prove its removal.
