How to avoid Matlab stop crashing on startup on Mac OS when using full-screen and split-screen functions?

Hello,

I'm using Matlab 2019b on macOS Mojave 10.14.6.

Half of the times I'm using the fullscreen / split-screen utilities of macOS, it causes weird problems in Matlab the next time I open Matlab, mainly 2 things:

• If I close Matlab app after I used split/full screen, then the next-time I open Matlab, it might get stuck on startup (usually while loading the command-line window). When this happens, I have to force-quit Matlab, and it will happen again and again each time I re-open Matlab. The only way to solve this, that consistently worked for me, is to delete a xml file related to the startup layout of Matlab (explained down below).
• Sometimes the windows of the help-browser and the figures disappear, and they don't appear again, no matter what. (typing 'figure' in the command-line, or trying to open a new help-browser, do not open any new window). Sometimes if I reopen Matlab it is fixed, and sometimes not, and then I have to delete the same xml file that I mentioned before.

As I said, the solution that worked for me, is to delete an xml file, related to the startup layout of Matlab. Instructions:

1) Open finder

2) Go -> Go to Folder (~/Library/Application Support/MathWorks/MATLAB/R2019b)

3) Delete 'MATLABDesktop.xml'

4) Reopen Matlab

I have no windows-arrangement app installed such as 'Magnet' or 'Rectangle'.

Searching the forum, I saw this problem happens to many people.

This solution is quite annoying, since it resets many layout settings that I have to reconfigure each time. Will it be fixed?

Thanks,

Ran,

Thanks for posting this! My MatLab would crash whenever I would set it to full screen. After closing it as side screen, Matlab liked to only stay side screened haha.

A proper fix/update would be better than this workaround

Have you reported this to [e-mail]? This looks like a Matlab bug that MathWorks engineers should be working on; not just this community forum.

I wasn't sure what is the right platform to report about this problem, I sent a mail now to [e-mail]

Thank you so much for sharing this!!!
