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!

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

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

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.
