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.
Preserve local-only messages and any custom Messages directory as well as the entire support folder; an IMAP copy is not an independent backup of local mail or settings. 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/MailMate~/Library/Preferences/com.freron.MailMate.plist~/Library/Application Scripts/com.freron.MailMate.MailMateShare~/Library/Containers/com.freron.MailMate.MailMateShare~/Library/Caches/com.freron.MailMate~/Library/Saved Application State/com.freron.MailMate.savedState
The cask also lists ~/Library/Caches/com.apple.helpd/Generated/MailMate Help*1.13.2; open the parent and remove only matching help files for that installed version, keeping Apple’s parent folder. Ordinary Homebrew uninstall also removes its managed emate link under the actual Homebrew prefix, independently of zap.
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 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 mailmate
What Mole lists
With Remove data and settings with apps off, the listed display-name Application Support/MailMate row starts unchecked. With it on, an eligible existing own unshared row may start checked; back up wanted mail and uncheck it to retain it; 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.
