Running 31.0.3 on an M1 Mac Studio with MacOS 15.3.2, no problems. On a back-up machine (M1 MacBook Pro) have updated to 15.4, and OBS 31.0.3 seems to be running as normal. Before I upgrade my main machine, I always like to check here to see if anyone is having problems after upgrading to the latest MacOS, this case 15.4. A "no problem" reply is also helpful. Thanks!
