R2021a runs very slowly on macbook air 2020 intel

After upgrading to Matlab R2021a, Simulink runs very slowly and often doesn't respond and freeze when creating and compiling models. I have a MacBook Air 2020 with Quad-Core Intel i5 1,1GHz, 8GB RAM, macOS Big Sur 11.2. Is there a way to improve the performance?

I have the same problem with simulink after upgrading to R2021a. Im running on a windows laptop i7- 2.6ghz and gtx 1660. On my workstation that is a way slower machine it runs perfectly fine

I have the same problem. Matlab runs very slowly (even if I don't use Simulink) and freezes very often. I use the same Macbook (but with Big Sur 11.3).

Hi Paul,

Please install the latest patch for R2021a to fix the issue.

You can find the patch in the MATLAB command window: Home > Help > Check For Updates

If the above method does not work for you, please grant full disk access to the MATLAB_R2021a app via the Security PAnel in System Preferences.
