Last week, after a long time, I tried again to work with the notation window of my BIAB 2000 for mac on my current Macbook with Sonoma 14.0. The well-known problems arose. Since pgmusic cannot yet offer a suitable upgrade, I called Apple. The solution would be to downgrade to an older operating system. Therefore my question: Does anyone know whether all the functions of Biab 2000 were still possible with Ventura?
