I bought WiFi Guard. It is a great tool and is working fine.
As the license allows to install it on a second machine, I thought I make an export of my device list and import it to the second computer. But the export ends with this error every time I try: "Unable to create file /Users/.../Documents/WiFi.xml". Same happens whether I export CSV or XML.
I bought WiFi Guard via Apple AppStore, version 2.1.2, using it on macOS.
Many greetings from Germany
