I’ve solved the problem but only with and old version of CubicSDR.
1) remove any previous installation
2) from the download page select Catalina as your OS and use the provided installer for the API on the resulting page. Install the API first then the app.
Now the RSP1A must be visible but the display console should appear messed up
3) Locate the CubicSDR app in the Applications folder and right click on it : select open.
4) edit the file info.plist
5) n the plist file change “true” to “false” (only the second occurrence from the end of the file.
I’ve got all the suggestions from the Support Team in few hours: I’m very impressed.
The app interface is terrible and many features are missing.
Good luck !
