If you're experiencing random freezing or find yourself frequently needing to force quit the Polymail app, the issue may be related to a corrupted or misconfigured Polymail Application Support folder.

Resetting this folder allows the app to create a clean environment, which can often resolve unexpected behavior without affecting your emails or system files.

How to Reset the Polymail Application Support Folder in Mac Desktop 

• Completely close Polymail.

• Make sure the app is not running in the background.

• Uninstall the Polymail app from your Applications folder.

• Open Finder, then use the shortcut: Command (⌘) + Shift + G.

• In the field that appears, enter: ~/Library/Application Support

• Locate the Polymail folder in this directory and move it to the Trash.

• Reinstall Polymail by downloading the latest version from our website.

Note: This process only removes Polymail’s local support data. It does not affect any other apps or your macOS files. When you relaunch Polymail, a new Application Support folder will be created automatically.
