I am asking this for the third time with more details, since there are no answers yet. Since my notebook isn't working, I am using the Cloud, but I'd like to get the notebook running again.
So, I have sagemath notebook installed on my Mac laptop, and it has been working fine until recently, maybe because I tried to run some 3d graphics program I found on the Sagemath manual. Then it froze up.
I can see all my files, but I cannot run any programs. There is no "evaluate" button. The box for a new program doesn't turn blue around the edge. If I open up a worksheet, and go back to the list of files, it says (running), though nothing is working. Also, the "Help" and "Report a Problem" and "log" buttons don't work. "Home" and "Sign Out" do.
I can sign out, log back in and it's still stuck. Restarting the Mac also doesn't help. Do I have to create a new notebook? Reinstall everything?
Help please !!!
thanks very much
