I just tried to download the converter using Safari but received error message
I did succeed in downloading the .dmg but when I installed it into the Applications folder and tried to open the file I received a message that the app was damaged and sould be moved to Trash.
After exporting the Bento DB as a .csv file I was able to import into Ninox. Problem resolved
Thank you for your information.
I tested it today and I could download the Bento converter and I could open the app in the Applications folder (it just gives an security message when you open it).
Please be aware that the import tool Bento-to-Ninox will only work properly with the latest version of Bento.
According to our information this is "Bento 4.1.2".
You can still download it from the internet.
