The log says says "Starting Notebook in Terminal" which means that it should have opened up Terminal.app so that you can type in a password. Did you perhaps not notice it? Try again and if Terminal.app doesn’t start up, you can try starting sage in a terminal as Dima suggests (Terminal Session

Can you start Sage in a terminal? (it is somewhere in the menus of the app) perhaps it's the antivirus that causes your problem - they are known to break things, in general On Friday, April 1, 2016 at 6:31:28 PM UTC+1, FG R wrote: > > I have also the same problem on MacOS X 10.11.3 El Capitan >

The cleaner solution is to add on top of your previous commits (all based on 7.1rc0), this will make the history more understandable. But, really, merging in the latest beta is not that bad either. The only downside is one extra log message, not that much of a deal. The code on the ticket is re

[sage-support] How to take out a matrix as common factors

Dear community, I'd like to show to my students how to obtain the structure functions of a Lie group, say SU(3). Therefore, I create a basis for the Lie algebra, normalized via the trace of the squares. Then, I defined a commutator function, and start calculating the algebra... However, I'd lik

Dear list, three weeks ago, I opened Trac#20190 to upgrade R to 3.2.4. This worked fine for me, but stumbled on a problem in another Sage installation (different system libraries). At the time I had no time to explore it. This turned out to be an upstrea
