Simulink Issue with Mac OS

I have just installed Matlab 2021a in my macbook pro (macOS 10.4.6). The Matlab part works normally; however, the Simulink part cannot work. The error message is as follow:

Caught "std::exception" Exception message is:

Error loading /Applications/MATLAB_R2021a.app/bin/maci64/simulink_plugins/sl_prm_engine_plugin/libmwsl_prm_engine_plugin.dylib. dlopen(/Applications/MATLAB_R2021a.app/bin/maci64/simulink_plugins/sl_prm_engine_plugin/libmwsl_prm_engine_plugin.dylib, 10): Symbol not found: __ZN8slprmeng35cleanBindingInfoOfAllChangedObjectsEP8SLRootBD

Referenced from: /Applications/MATLAB_R2021a.app/bin/maci64/simulink_plugins/sl_prm_engine_plugin/libmwsl_prm_engine_plugin.dylib

Expected in: /Applications/MATLAB_R2021a.app/bin/maci64/libmwsl_prm_engine.dylib

in /Applications/MATLAB_R2021a.app/bin/maci64/simulink_plugins/sl_prm_engine_plugin/libmwsl_prm_engine_plugin.dylib: No such file or directory: No such file or directory

Does anyone know the possible reason? I wonder if it is due to a lack of a compiler, like XCode.

Thanks!

Just to check, did you really mean macOS 10.4.6 (which was last supported with release R2006b according to the system requirements; the R2007a system requirements lists 10.4.7 as the earliest supported OS version) or macOS 10.14.6?

Same issue for Matlab 2021a on MacOS 11.5. Can some one help look it?

[Walter Roberson]

By the way, the missing symbol is _slprmeng::cleanBindingInfoOfAllChangedObjects(SLRootBD*)

I have the same problem, i can't solve it, can anybody tell me how to solve the problem.

[Pierre Riedinger]

Exactly the same problem. It is imposible to load Simulink.

Can you update to R2021a U3 and check if it resolves the issue

[Pierre Riedinger]

I update with R2021a r5 aout 2021 and all work. Thanks.

How can I update R2021a on Mac OS 11.6? Or is there another way to get simulink work?

@Rebecca Humborg

In MATLAB, the command window, select the "HOME" tab (the left-most tab in the list.) Then in the list of tools just below the tab list, about 3/4 of the way to the right, you will see a Help area in the "Resources" section. Left click on that to open a menu, and select "Check for Updates" from that menu. That will open the Add-Ons Manager to the "Updates" tab.

If a MATLAB update is available, it will be listed; select it and ask to install. Note that this will require shutting down MATLAB, so be sure to have saved your files first.
