Matlab R2021b freezes on Mac Big Sur

Helly, I am using Matlab R2021b on a MacBook Pro. It is running on Big Sur 11.6, and it has 16 GB ram, a 2GHz Quad-Core Intel i5.

However, Matlab runs extremely slow and freezes often. It is actually completely disfunctional.

I tried most of the solutions offered on the internet: reinstall Matlab, reinstall Big Sur, install other versions of Matlab,update Java, ... nothing seems to work.

Do you have a possible solution to fix this issue?

Thanks!

Same problem here. MacBook pro I9 16". My mac with M1 works perfectly, only the Intel version does not work. Just freezing for 5-10 minutes.

Having the same issue. Matlab keeps hanging after I plot a graph. I am using a 2018 macbook pro with intel i7 core.

I was able to solve it by launching the MATLAB.exe file from terminal. Find the location of your MATLAB application file (most likely in your Applications folder on your hard drive). Once you have done that, right click on MATLAB R2021b and click "Show package contents". Navigate into the Contents folder and then into the MacOS folder. There should be an exe file called MATLAB. You need to copy that directory and use that in terminal. It should be something like, or exactly, /Applications/MATLAB_R2021b.app/Contents/MacOS/MATLAB. When you enter this directory into terminal, it seems to directly open this exe (and possibly run as Admin?). I had the exact same problem and have escaped it ever since. Hope this helps

This solution has been working, although I dont know what it is doing that is different from regular startup. Hopefully they fix it in an update, but until then, we will just have to launch it from the terminal. Thank you for your help, saved me a lot of time spent crashing in class.
