After updating my trial machine (M1 MBP 14) to the new Sonoma 14.5, OBS 30.1.2 seems to run just fine. But before updating my main machine (M1 Mac Studio) to 14.5, wanted to give it some more time in case any of you encounters a problem. In the meantime, I'll keep experimenting on the MBP, and post anything I learn on this thread.
