2019-02-21 02:34:27 +0200 | answered a question | Sage takes very long to start—why? I've been wrestling with this ever since 10.14, "Mojave" came out. I gave an answer to this question, sagemath 8.6 could not work normally on mac 10.14.3 with my own workaround, but your suggestion, As I said in my previous answer, I have mentioned this before in the sage-devel forum. I will raise the matter there again if 8.7 doesn't clear it up, and your workaround would seem to point to a very easy solution to this problem. |

2019-02-09 06:22:40 +0200 | commented question | sagemath 8.6 could not work normally on mac 10.14.3 For my part, I am using sage-8.6-OSX_10.14.2-x86_64.app.dmg on 10.14.3. But this has been a problem ever since Sage 8.4. The common denominator has been "Mojave", in versions 10.14, 10.14.2 and now 10.14.3. It looks like Sage 8.7 is about to be released, and if this hasn't cleared up, I guess I'll mention it again on the sage-devel forum. |
2019-02-09 06:08:17 +0200 | commented answer | sagemath 8.6 could not work normally on mac 10.14.3 The Sage icon on my menu bar (when it finally appears!) lists 'View Log" as an option right above "Preferences...". I am using Safari, but I don't think it should matter. It's still good to know how to invoke the console directly in case the Sage icon doesn't appear. You can set the default browser from the "Preferences..." option on the menu bar, but that's only after you have managed to get the Sage icon to appear in the first place... |

2019-02-08 01:13:48 +0200 | answered a question | sagemath 8.6 could not work normally on mac 10.14.3 I have also been having this same problem ever since upgrading to Mac OS 10.14, "Mojave". I have since found a workaround that isn't too painful. After starting up the double-clickable app, use the Mac terminal application to execute the Mac Console utility:
At the end of the log file, you should see a message:
After pasting the URL into your browser, you should immediately see the notebook interface, and you can then use Sage. Despite what the message says, you will still have to do the copy/paste operation on subsequent Sage invocations. If you wait for about a minute or two, the Sage icon will eventually appear on the menu bar. If you are patient, you can skip the copy/paste step and wait a couple of minutes for the app to open by itself. There are also ways of opening the notebook directly from the command line, see Running the notebook. |

2019-01-16 04:17:44 +0200 | answered a question | Identity in a quotient Group You can compute a rewriting system by: Then In general, it is not possible to guarantee that the Knuth-Bendix procedure will terminate to produce a confluent rewriting system. This is why the system cannot automatically reduce arbitrary expressions. In fact, it seems that Knuth-Bendix fails to terminate on your example. See the make_confluent() documentation for more information. |

2018-10-30 08:42:00 +0200 | asked a question | problem running Sage on MacOS 10.14, Mojave I recently installed sage-8.4.rc1-OSX_10.13.6_x86_64.app on my Mac and ran it under macOS 10.13, High Sierra with no problems. A few days later I noticed that sage-8.4-OSX_10.13.6-x86_64.app became available, so I installed that version, too, again with no problems under macOS 10.13, High Sierra. But then a few days later I upgraded my MacOS to 10.14 Mojave, and I have had problems getting Sage to run properly. After clicking on the Sage app, the browser icon "bounces" in the dock for a few minutes before stopping altogether, and Sage never starts at all. Oddly enough, I have actually been able to run both sage-8.4.rc1-OSX_10.13.6 as well as my older copy of Sage 8.3 under Mojave if I wait for a minute or a minute and a half for the browser to start and then another few seconds for Sage to start. But neither sage-8.4-OSX_10.13.6-x86_64 nor sage-8.4-OSX_10.11.6-x86_64 can be persuaded to run at all. The long startup time with sage-8.4.rc1 is a very minor issue, and I have been getting along pretty well with it. I am not particularly enamored of the Mojave release, and I could always reinstall High Sierra if necessary. Has anyone else seen these problems? If so, I thought maybe the developers would like to know about it. |
