Open Multiple Matlab on Macbook

Hi All,

I would like to open 2 different versions of Matlab at once. When I open the Matlab 2019b and 2020a on my macbook, I have a pop-up window: "MATLAB_R2020a.app would like to access files in your Documents folder.". Once I click on the "OK", I have another pop-up window: "MATLAB_R2019b.app would like to access files in your Documents folder.". This is repeated over and over. I do not want to get this window everytime. Do you guys have any ideas for removing?

Thanks,

Are you using Catalina?

I do not get anything like that in High Sierra but I have heard of permission being requested in Catalina.

Hi Walter,

Yes, I am using Catalina. I remember that I did not have this message when I was using a previous version of OS X. Do you have any ideas to figure it out?

Thanks,

Hi Walter,

First of all, I appreciate your help for solving thiss. I have solved this issue. I got a clue from your message. For the person who might have the same issue, I will leave the solution over here.

If you guys have the pop-up windows when you open two or more different versions of MATLAB on your macbook, you can figure it out as following:

1. GO TO "System Preference"
2. go to "Security & Privacy"
3. go to "Full Disk Access" on the left panel
4. check on "MATLAB_R20xxx.app"

Then open both MATLAB2019 and MATLAB2020, we will not see the pop-up windows anymore.

Thanks,
