How to Uninstall MailMate on Mac

MailMate can hold downloaded mail, indexes, custom bundles and settings locally. Back up its support folder and confirm your IMAP account holds the messages you need before removing it; a server copy does not automatically preserve local customization. The recorded test used a direct download, not a Homebrew installation.

Remove the app and inspect its data

If MailMate can run on this Mac, quit it first and then move MailMate.app from Applications to Trash. The recorded Intel-only package could not launch on the test Mac without Rosetta, so no live account was configured. The manual documents the support folder and preference plist as settings and database locations. A custom Messages folder may be elsewhere if its location was changed in MailMate; check that setting before clearing anything. Vendor guidance.

Check the result

ls -ld ~/Library/'Application Support'/MailMate ~/Library/Preferences/com.freron.MailMate.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 Application Support/MailMate, the Share container and preferences, including custom settings and downloaded mail. 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 mailmate

What Mole lists

The display-name Application Support/MailMate row is for review and unselected by default; exact bundle-ID preferences and caches are normally selected. Do not infer that a never-launched test validated mail data deletion or preservation.

What this test covered

The MailMate 1.13.2 x86_64 app was copied from the official archive and removed on September 20, 2026. Launch failed without Rosetta. Its Share script was removed, while a container hit a Trash permission error; no mailbox or IMAP sync was tested.
