I am interested in one aspect. For "security", MacOS might restrict softwares access to directories. If someone tries this and find some difference, maybe some more users will be helped.
Step 1. Remove the /Applications/SageMath-9.0.app which does not work. (This test is for such SageMath-9.0.app. If it is working do not remove it since the test does not make sense anyway.) The application might be shown /Applications/SageMath-9.0 in Finder. Step 2. In the Terminal window of an administrator's account, use this command: $ cd /Applications/SageMath-9.0.app/Contents/Resources/sage $ open -a /Applications/SageMath-9.0.app The first command changes the working directory to SAGE_ROOT. The second command tells the full pathname to the application and invoke it. I surfed through the internet and found the error message is from bash. It tells bash found no current working directory when it is invoked. If Step 2 is OK, please proceed to the next step. Step 3. Quit SageMath.app and the browser. Then, double click /Applications/SageMath-9.0.app. If Step 3 fails, then please proceed to the next step. Step 4. Try the procedure of Step 2 again. I will try to find what is going on there on the isolated island Catalina. 2020年3月18日水曜日 0時04分16秒 UTC+9 Steve Emmett: > > I am having maybe a similar issue.
