Simulink error on mac

hi, i just installed the newest Matlab with Simulink but when i create new model on simulink, the header just blank. i can't see any logo such as library browser, save, print, debug, modelling etc. how can i fix this?

this is how it suppoused to look like

but this is what my simulink looked like

The first thing I would check would be System Preferences, Security and Privacy, first tab, and see if MacOS has any notes there about applications having asked for access.

In some cases it might be necessary to specifically grant MATLAB disk access.

what should i change in my System Preference? the Accsessibility (in Security and Privacy)for MatLab is already activated. i've asked to Support Center for help, but it doesn't solve anything. the problem is still there.

Hello Tania,

I understand you are unable to view the library browser in Simulink. This might happen because your MATLAB installation path or toolbox cache got corrupted. Please follow these troubleshooting steps to restore the Simulink toolbar:

• Try running the following commands in MATLAB’s command window to restore the MATLAB search path to its default settings and to update the cache.

restoredefaultpath 
rehash toolboxcache 

• Run the following command to rebuild Simulink and Library menus and toolbars:

sl_refresh_customizations 

• Try resizing the window after the Simulink window opens by increasing or decreasing its width. When you start seeing something, adjust the width so that it perfectly fits the contents of the window.
• Sometimes, issues like this can be resolved simply by restarting or reinstalling MATLAB and Simulink. Close all MATLAB instances and then restart MATLAB.

I hope this helps you to restore the Simulink toolbar!

Regards,

Shuba Nandini
