20200530 15:34:13 0500  answered a question  Sage 9.0 installation issues on macOS 10.15.2 Catalina For the purposes of recording some additional instructions in a semipermanent place (since the Wiki seems to be deemphasized as a location for such instructions), here are some instructions combining Samuel's answer, some on Google groups (https://groups.google.com/forum/#!top...), and a writeup kindly provided by sarahmarie belcastro. DO NOT UPVOTE. To run Sage binaries on Mac OS 10.15 (Catalina) and above, extra steps may be necessary. Here are some possibilities; see the other answers on this post for much more detail and other, perhaps better, possibilities.

You could try to use the version of "Open" that appears then. Another option could be to use the answer here regarding Apple's (relatively) new security regime. I'm not sure if this is what you were experiencing, but having this answer may help if others land on this question due to the Apple security checking issue.

20191121 20:37:48 0500  commented answer  Does sagemath move asterisks down? Jim, as you know another possibility would be to write this in PreTeXt which has some people developing it who are actively thinking about the listings and other packages and font issues. If you are at the NES/MAA meeting this weekend I will be glad to chat briefly. Unfortunately I agree with Emmanuel that some very useful LaTeX packages end up sort of in limbo.

20190702 21:24:30 0500  answered a question  Calculating Cauchy Integrals in Sage Identical answer (not full, unfortunately) to what I posted on SO. You're probably going to have to parametrize your integration domain (circle, here). Or use a Cauchy residue type theorem, as here. Here is an interesting Sage cell instance by Jason Grout and Ben Woodruff that might help you get started on how to calculate some of them; unfortunately, sometimes these integrals are very tricky to do exactly. See this sagesupport thread for an easier example, though I don't think in the end it fully worked because of a Maxima bug. Relevant code: The last two lines do a numerical and exact (if possible) result, respectively.
