Livid DS1 live 11 script not recognized

[jumphole]

Hi, I've installed from m4m8 Python Script Live 11 and Livid Python Script Live 11 in my Live 11.3.13 (OS 10.15.7) to work with a DS1. It works on my laptop but not on my Mac Pro, both with same OS and Live version. On the Mac Pro Live 11 the script doesn't works and the DS1 is not in the control surface list. Can you help me, Please? Thanks
