Hi,
I downloaded 2020b update 5 version which said to be compatible with rosetta 2. Although I downloaded the right version matlab works incredibly slow I even cannot close the app. I tried to do what https://www.mathworks.com/matlabcentral/answers/262442-java-heap-space-out-of-memory-problem this problem says but even though I disabled the MathWorks Source Control Integration it still was slow. Is it about the java heap memory and how much should I inrease that? Thanks.

The 2022 version is so slow in MacOs Ventura. Did anyone found a solution other than installing the 2017 version?

In my case, the lag disappears if I start MATLAB from Terminal everytime. It's strange to see that while it could run good, it is running slow when started from the ususal App icon.

Mine runs REALLY SLOW. A job on my old macbook (2016) with 2.8GHZ intel i7 takes 5 minutes. On the new macbook M1 it takes 8 minutes. 60 percent longer!
