I am having maybe a similar issue. Im on MacOS 10.15.3 I've successfully used 8.9 for quite a while. I downloaded *sage-9.0-OSX_10.15.2-x86_64.app.dmg <http://mirrors.mit.edu/sage/osx/intel/sage-9.0-OSX_10.15.2-x86_64.app.dmg>.* I did the install selected SageMath-9.0.app in Applications.
Safari starts up and overlaid on that screen is the following error message: [image: Screen Shot 2020-03-17 at 101002 .png] The only log entry is: shell-init: error retrieving current directory: getcwd: cannot access parent directories: Operation not permitted. Maybe not exactly like your but I would tend to agree that something that was hooked up in pre Sage 9.x is now not there in Sage 9.x On Sunday, January 5, 2020 at 2:39:50 PM UTC-5, Murray Eisenberg wrote: > > When I open SageMath-9.0.app under macOS Catallina (10.15.2), I get an > immediate pop-up error window saying, "Jupyter Server failed to start". > > The log shows: > > ┌────────────────────────────────────────────────────────────────────┐ > │ SageMath version 9.0, Release Date: 2020-01-01 │ > │ Using Python 3.7.3.
