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.
