I just downloaded that Sage 9.0 app for Mac OS X (Catalina). When I try to open it, it says that the Jupyter server failed to start. I can't open a terminal session either. The log says this:

shell-init: error retrieving current directory: getcwd: cannot access parent directories: Operation not permitted shell-init: error retrieving current directory: getcwd: cannot access parent directories: Operation not permitted

I had been using Sage 8.7 and it was working fine. I just downloaded 9.0 and deleted 8.7. Could this have caused the problem?

Thanks!

Could it be that Sage 8.7 was installed under macOS 10.14 Mojave and kept working after a system upgrade to macOS 10.15 Catalina?

Granting Sage access to all folders solved the problem for me. Go to Systems Preferences -> Security and Privacy -> tab Privacy -> Full Disk Access. Add Sage to the list of applications.

The problem is probably due to the reinforced measures by Apple in macOS 10.15 Catalina to prevent non "notarized" apps from running.

The solution is probably to unquarantine the SageMath app. See more details at
