giuliomoro No... I also tried to turn off my macOS firewall, and received the same error in PD

I just tried the same experiment with my Bela Mini (and the simplified PD patch), and had the same result, which leads me to agree that the issue is perhaps not with the the Bela but on the computer end... I recently updated my macOS to 15.4... could it be a macOS issue?

Update:
I re-tried our PD test patch on my school computer & it worked without error (screenshot below). Also, more complex program (from a year back, above) is working as well. The school machine is macOS 14.7.5. So perhaps it's a macOS thing?

      I don't know what they are doing that makes this stop working ... can you access the Bela IDE at 192.168.7.2?
