- Press and hold the “Option” key and choose “Go” and “Library” from the menu bar
- Navigate to the “Containers” folder
- Delete the “Netmo” folder or the “at.agross.netmo” folder (depending on your macOS version)
- Important: now restart your Mac!
- Start Netmo Classic again
The following screenshots explain once more how to delete Netmo Classic’s settings folder.
