Clearing AppData in Mac and Linux
If you suspect that your instance of MatterControl is suffering from a corrupted configuration file, it may be necessary to clear the contents of your MatterControl local data folder.
You may do this by navigating to the system folder named: ~/.local/share/MatterControl, and deleting all of its contents.
Please note that by deleting the contents of this folder, all of your saved configurations will be permanently deleted. If you were logged in than your settings were saved to the cloud and will be restored when you log back
Once MatterControl has been restarted, you should be prompted with the normal startup procedure where you can log back in or create a new printer.
