I installed Sage 9.2 (the .dmg file) on MacOS (Catalina 10.15) and everytime I click on sage, I get a notification saying "“python3.8” cannot be opened because the developer cannot be verified." then I click cancel and after that I am not able to type anything in Sage. This message shows up in the Terminal:

Last login: Wed Nov 18 11:50:19 on ttys000 /Applications/SageMath/sage ; exit; Lela@MacBook-Air ~ % /Applications/SageMath/sage ; exit; /Applications/SageMath/src/bin/sage-python: line 2: 79727 Killed: 9 sage -python "$@"

[Process completed]

Can someone please help me? I really don't understand what to do to make it run.

Thanks in advance! Lenka

Rather than hitting "cancel", you should be able to open the "Security & Privacy" panel in System Preferences and allow the application to open.
