The entire X server crashing is most likely to be a graphics driver problem.

Things worth trying would be to use a different driver or start Mathematica with the -mesa command line flag.

Today, I moved Mathematica to another computer. The command line interface works perfectly, but the GUI doesn't work. When I open Mathematica, after loading the kernel in the splash screen, my laptop is suddenly reboot. I post a video for that. I have tried all the possible answers on the internet, but I found nothing that resolve the issue. I hope this forum will help me.

I use Mathematica Student 11.2.0 for Linux 64-bit. The operating system is Ubuntu 16.04 LTS.

This is some useful information about the machine.

The entire RPi rebooting is likely due to hardware instability.

Possible things to look at would be the power supply voltage and/or CPU temperature.

Got some crashes too, Mac OSX, 16GB of memory

Long-time user, big-time fan, and first-time replier:

I just upgraded to 11.3 (Mac OS X x86 64-bit) and the following crashed the kernel:

Map[Normalize, 
   RandomVariate[
    MultinormalDistribution[ConstantArray[0, 6], IdentityMatrix[6]], 
    10^6]];

I was able to isolate it to Map and to the size of the list, where 10^4 works, but 10^6 does not. Therefore, I had to go back to 11.2, where there is no problem.

So the problem is not just with the Macs in Imperial College, London…(where many of us have given up with 11.3 - so are sticking doggedly to 11.2).

Interesting that you just need to call Simplify on a big piece of code to create the crash. Our problems similarly involve transformations of complicated functions that require a lot of memory.

I suspect a memory management problem in 11.3. It may be specific to Mac OSX as the programmer at Wolfram that I exchanged some of my problem files with was running another system and could not replicate the crashes.

It would be nice if Wolfram would wake up, take interest and fix such a fundamental error.

Ditto, I use a mac (love it!), I had had issues with earlier 11, but 11.2 is good and 11.3 seem fine so far.

I suggest two things:

A typical mistake is to not see WR's installation instruction page (for mac) which says to (uninstall) the old version before installing the new (it's ok, you can still correct). go read that off the wolfram help pages and go step by step, but read #2 first.

You may need to rename these two folders: /Users/whoami/Library/{Wolfram,Mathematica} (when mathematica is not running). Restart your re-installed mathematica. You'll LOOSE settings and DATA stored in those two places (remediating that i don't mention), possibly paid download content (many people don't need to worry about it at all). The FOLDERS will be remade with defaults that are "surely compatible" with 11.3. (if you keep your 11.2 Library folder, and you may need to, you are bound to fix problems that might cause. as far as i know there are none currently but there has been in the past, issues re-using the Library/app folder's old settings)

Apple has great forums (the above advice about ~/Library can be found there and at the following places).

A good online resource for fixing minor issues on Apple devices, to avoid Support calls or trip to Apple store, is:

and

When you get these crashes, do you know offhand whether anything was happening in the user interface, such as scrolling of the mouse hovering over code? I've seen problems involving those sorts of situations (though on Linux), one of which I did manage to reproduce and report.

The advantage of LTS releases is that they keep getting bug fixes, but they don't (often) get new bugs introduced, as no new features are added. Thus in the LTS the number of bugs goes down over time, while in the Current there's a balance between fixes and breakages.

I think that before experimenting with an LTS release, Wolfram should address a much bigger problem: bugs in certain functionality areas just don't get fixed. That's why I keep complaining about the Graph stuff—there are many serious bugs that haven't been touched at all through several releases. Actually, this functionality area isn't getting any new features either, so the bug number at least isn't going up ...

[To be fair, some Graph-bugs did get fixed, but most serious ones I found (silent wrong results, random results, etc.) still persist after multiple reports.]

Running 11.3 under Windows 10, I have the general impression that the software is less stable particularly when accessing the documentation center for the first time. Things seem to momentarily hang, and sometimes crash.
