She looks in Activity Monitor and says > she has killed all of the python processes, but still cannot launch SageMath. it's most probably a stale "lock" file, just a file created by a process to indicate that it's running; such a file is cleaned on a normal exit, but not in case of a crash. I must say I don't know much about this app, I'll cc to one of the authors. Marc, could you have a look? The app has a dedicated issue tracker: https://github.com/3-manifolds/Sage_macOS/issues it might be better to report there. > > The last time this happened we removed and then reinstalled SageMath.

I'm running Sage (and writing this email from a 7 y.o. machine just fine). A quick way to run Sage is to use https://cocalc.com (you can upload Jupyter notebooks there to run; you can even use it for free, but to make it run better you'd need to pay something like $7 per month) There are several other ways to run Sage locally on your mac, but let's try things in turn first.
