I used to work with T3.2. Now that I want to work on T4.1 nothing works.
I had to install Teensyduino from here on Catalina (Teensyduino has full access to your Documents folder): https://www.pjrc.com/teensy/td_download.html
I was able to get rid of the error about SD.h (see bottom of code) by deleting by hand the SD folder in the /Applications/Teensyduino.app/Contents/Java/libraries/ (seems weird to me that SD is double with this standard Teensyduino .app!).
What I could not solve is the AudioStream.h errors.
I checked this thread https://forum.pjrc.com/threads/67864-Audio-applications-error which has the same error but I'm on MAC not PC. There's no "installer" for the Teensyduino. Just the Teensyduino.app. All permissions are ok. No anti-virus active. I don't know what to do.
