I have a student, Mac OS X 10.7.5, installed the 10.6-app, startup takes her to Terminal, whence the server tries to start and give the error IPython parent 'Users/username/.sage' is not a writable location, using a temp directory. then a bunch of alarms and stuff, and OSError: [Errno 13] Permission denied: 'Users/username/.sage'
I tried reinstalling Sage, and got the same problem. How can I help this student?
