I had Mathematica 12 installed ten days or so ago (and just now re-installed) on my university computer. Although I do seem to be able to run sustained programs for a day or so, it has also totally unexpectedly crashed on various occasions, even running a few basic lines of commands.

I'd written to support@wolfram.com, but only received as a reply so far:

"In order to better diagnose the issue, please provide more information such as:

-A simple code sample of, say, 10-20 lines that essentially illustrate the issue.

-A screenshot of any windows that show up.

-Any error messages you see when you try to open Mathematica."

Hard to do if everything disappears.

I've been using Mathematica intensively for decades now, and have never encountered a problem remotely similar to this.

I've also been running version 12 at home, and this phenomenon has not occurred there.

Guess I'll just use Version 11 on campus (for which I've never had such a problem) until this matter resolves itself.

This is my "hardware overview":

Model Name: Mac mini Model Identifier: Macmini4,1 Processor Name: Intel Core 2 Duo Processor Speed: 2.4 GHz Number of Processors: 1 Total Number of Cores: 2 L2 Cache: 3 MB Memory: 4 GB Bus Speed: 1.07 GHz Boot ROM Version: 75.0.0.0.0 SMC Version (system): 1.65f2 Serial Number (system): C07DV0VLDD6L Hardware UUID: 58037265-42DA-53A2-8C8C-EF4D37D3AFB6

Any relevance?

Any more needed? Insightful?

    $\begingroup$ 1) What OS version are you running? 2) Are there any crash logs under "User Reports" in Console.app? $\endgroup$ – Brett Champion May 7 at 21:37
  • $\begingroup$ Agree with @BrettChampion: If you can provide any crash log (for the frontend or kernel) then we can analyze the crash at Wolfram using debug symbol tables we keep for released builds. Also any specific information leading up to the crash is incredibly helpful to narrow down the millions of possibilities. $\endgroup$ – Arnoud Buzing May 7 at 22:03
  • $\begingroup$ Thanks for the comments/suggestions! The OS is macOS Sierra 10.12.6. Zero messages in my Console. The last crash happened just minutes after re-installation, after entering a few basic commands (no immediate record of them at the moment)--clearly nothing particularly challenging, in the least. How do I find a "crash log" when and if one is available? $\endgroup$ – Paul B. Slater May 7 at 22:18

    $\begingroup$ If you right-click on the entry under "User Reports", you can reveal the actual file in the Finder. Email that to support. $\endgroup$ – Brett Champion May 7 at 22:33
