Matlab 2021a is running extremely slow on MacBook Pro. How can I fix this?

117 views (last 30 days)
I recently purchased a new MacBook Pro. It is running on Big Sur 11.4, and it has 16 GB ram, a 2GHz Quad-Core Intel i5.
I use Matlab 2021a on it. However, this program runs extremely slow. 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, reset SMC, I put source control to none in the Matlab preferences, I increased the java heap memory, ... nothing seems to work.
What could be a possible solution to this? All other programs run just fine.
Thanks

Hey Adriaan,
I had the same issue on my personal MacBook Air after upgrading to 11.4, and it was super frustrating. Yesterday I installed the Update 3 Patch for R2021a and this has fixed my issues.
Hope that helps,

Neither disabling "Source Control" nor giving MAtLab full disk access has made an appreciable difference
