I edited the code back to original and tested how SageMath starts up. Deprecation warning does not block start-up. There remains some more mystery in start-up of double clickable SageMath.app of MacOS.
For possible users who encounter the same symptom of SageMath, I leave some record. Step 1: I copied SageMath9.1beta8.app in /Users/Shared/SagemathTestground. Step 2: I double clicked the copy /Users/Shared/SagemathTestground/ SageMath9.1beta8.app --------> Mac dialogue appeared an reported failure of jupyter server to start. Step 3: I used "view log" to read the log. The log was incomplete. It seemed patching was on the way. Step 4: I started /Users/Shared/SagemathTestground/ SageMath9.1beta8.app/sage from the command line. --------> Plenty of messages on patching were displayed. --------> Then, a deprecation warning on \Q in the definition of _macaulay2_init_ appeared. --------> sage prompt appeared. Step 5: I quitted sage and edited the relevant file and silenced that warning. Step 6: I invoked sage from command line and verified warning message is silenced. Step 7: I double clicked /Users/Shared/SagemathTestground/ SageMath9.1beta8.app. --------> Jupyter server started up and Sagemath was OK. Step 8: I put the code back in original for testing the software for sage-support-group. Step 9: I quitted /Users/Shared/SagemathTestground/ SageMath9.1beta8.app and double clicked it again. --------> Jupyter server started up and Sagemath was OK. Lesson? Patching at the initial invocation might fail occasionally. And, retrying initial invocation of SageMath several times might help. Deprecation warning seems not the real obstruction. -- You received this message because you are subscribed to the Google Groups "sage-support" group.
