Have you tried going into MATLAB Preferences -> General -> Java Heap Memory, and making that larger? After you do that, you will need to restart MATLAB.
Compatibility issue between Simulink and Mac OS High Sierra

I downloaded Matlab r2017b after upgrading my Mac to High Sierra, as Mathworks advise. But know Matlab is freezing when I start Simulink (opening a project, without even running it most of the time). I get a bunch of Exception Errors in the Command Window :

Is anyone having that problem too? What did you do to solve this problem? I really need Simulink and don't want to downgrade to Sierra again...
Thanks for your time!

I understand that you have already tried increasing the java heap memory available for MATLAB.
The other error 'GC overhead limit exceeded' can occur when the Java Garbage Collector has exceeded its overhead limit.
To disable the overhead limit, add the following line to the java.opts file:
-XX:-UseGCOverheadLimit
If a java.opts file already exists on your MATLAB path, add the above mentioned line to this file. If the file does not currently exist on your machine, please create a text file called java.opts and place this file in the location:
$MATLABROOT/bin/$ARCH
where, $MATLABROOT is the MATLAB root directory obtained by typing the following at the MATLAB Command Prompt:
matlabroot
and $ARCH is the output of typing the following at the MATLAB Command Prompt:
computer('arch')
Hope this helps.
